https://github.com/Broadcom/stblinux into soc/dt This pull request contains Broadcom ARM-based SoCs Device Tree changes for 6.10, please pull the following: - Laurent converts the Raspberry Pi firmware DT binding to YAML, updates the firmware driver to use the proper 'struct device' reference for DMA mappings and drops unneeded properties from the DT node and finishes by removing the duplicate firmware-clocks property to bcm2835-rpi.dtsi. He also added support for the CAM1 camera interface regulator. - Uwe adds a pinctrl-based multiplexing description to allow the use of I2C0 pins to allow usage between the 40-pin Raspberry Pi header and the CSI and DSI connectors. He then describes the PCF85063 RTC device available on the CM4 I/O board making use of that pinctrl-based muxing. - Arinc updates the Asus RT-AC3100 and RT-AC88U DTs to have proper LED colors and function properties, NVMEM MAC addresses and removes duplicates and unnecessary properties and does a few Device Tree cleanups.. He then adds support for the Asus RT-AC3200 (BCM4709-based) and RT-AC3500 routers. - Jean-Michel adds DT nodes for the CSI Unicam camera interfaces on the Raspberry Pi 4 / BCM2711 SoCs - Florian adds support for the Ethernet LEDs on Raspberry Pi 4 B and Raspberry Pi 4 CM boards. * tag 'arm-soc/for-6.10/devicetree' of https://github.com/Broadcom/stblinux: arm: dts: bcm2711: Describe Ethernet LEDs ARM: dts: BCM5301X: Conform to DTS Coding Style on ASUS RT-AC3100 & AC88U ARM: dts: BCM5301X: Add DT for ASUS RT-AC5300 ARM: dts: BCM5301X: Add DT for ASUS RT-AC3200 dt-bindings: arm: bcm: add bindings for ASUS RT-AC5300 dt-bindings: arm: bcm: add bindings for ASUS RT-AC3200 ARM: dts: bcm2835: Add Unicam CSI nodes ARM: dts: BCM5301X: remove earlycon on ASUS RT-AC3100 and ASUS RT-AC88U ARM: dts: BCM5301X: remove duplicate compatible on ASUS RT-AC3100 & AC88U ARM: dts: BCM5301X: provide address for SoC MACs on ASUS RT-AC3100 & AC88U ARM: dts: BCM5301X: use color and function on ASUS RT-AC3100 and RT-AC88U ARM: dts: bcm2711-rpi-4-b: Add CAM1 regulator ARM: dts: bcm2711-rpi-cm4-io: Add RTC on I2C0 ARM: dts: bcm2711-rpi: Add pinctrl-based multiplexing for I2C0 ARM: dts: bcm2835-rpi: Move duplicate firmware-clocks to bcm2835-rpi.dtsi ARM: dts: bcm283x: Drop unneeded properties in the bcm2835-firmware node firmware: raspberrypi: Use correct device for DMA mappings dt-bindings: arm: bcm: raspberrypi,bcm2835-firmware: Add gpio child node Link: https://lore.kernel.org/r/20240429213703.2327834-2-florian.fainelli@broadcom.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A updates for v6.10 1. Support for handling notification pending interrupt(NPI) The FF-A uses the notification pending interrupt to inform the receiver that it has a pending notification. This is a virtual interrupt and is used by the following type of receivers: - A guest/VM running under a hypervisor(normal world usecase) - An S-EL1 SP running under a S-EL2 SPMC(secure world only usecase) Also, when the FF-A driver is running inside a guest VM under an hypervisor, the driver/guest VM doesn't have the permission/capability to request the creation of notification bitmaps. For a VM, the hypervisor reserves memory for its VM and hypervisor framework notification bitmaps and the SPMC reserves memory for its SP and SPMC framework notification bitmaps before the hypervisor initializes it. These changes include skipping of creation of notification bitmaps, some refactoring around schedule receiver interrupt(SRI) handling and addition of support for NPI. 2. Support for FF-A indirect messaging The FFA_MSG_SEND2 can be used to transmit a partition message from the Tx buffer of the sender(the driver in this case) endpoint to the Rx buffer of the receiver endpoint and inform the scheduler that the receiver endpoint must be run. Apart from these two main features, there is an optimisation to avoid queuing of a work when already running on the worker queue. * tag 'ffa-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Avoid queuing work when running on the worker queue firmware: arm_ffa: Fix memory corruption in ffa_msg_send2() firmware: arm_ffa: Add support for FFA_MSG_SEND2 firmware: arm_ffa: Stash the partition properties for query purposes firmware: arm_ffa: Fix kernel warning about incorrect SRI/NPI firmware: arm_ffa: Add support for handling notification pending interrupt(NPI) firmware: arm_ffa: Refactor SRI handling in prepartion to add NPI support firmware: arm_ffa: Skip creation of the notification bitmaps Link: https://lore.kernel.org/r/20240426105051.1527016-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.10 1. Basic support for SCMI v3.2 pincontrol protocol SCMI v3.2 introduces pincontrol protocol which is intended for controlling pins and their configuration. The pin control protocol provides commands to: - List the pins, groups of pins, available functions, and their association with each other. - Set the parameter configuration and multiplexing of the pins or groups of pins - Optionally request exclusive access to a pin or group of pins. - Optionally configure the permissions of an agent to access a pin or group of pins. These changes adds basic support for the same in the SCMI core layer and an implementation of the generic scmi-pinctrl driver with associated DT bindings. 2. Framework support for multiple vendors custom protocols With the fixed space for vendor protocols, the possibility of having multiple vendors implementing distinct SCMI vendor protocols with the same overlapping protocol number is very high and with the need to support them all in a single kernel image or a module is also high. In order to implement the same we assume: - vendor protocols has to be tagged at build time with a vendor_id - vendor protocols could also optionally be tagged at build time with sub_vendor_id and implementation version At the initialisation all the built vendor protocols are registered with the SCMI core using a key derived from the above tags 3. Logging and tracing improvements This includes using dev_err_probe() to bail out from probe, adding message dump traces for bad and unexpected replies and widening of the tag buffer in trace_scmi_dump_msg to allow diverse tag names 4. Miscellaneous updates or improvements This includes adding the accessor function get_max_msg_size() used in pinctl protocol, updation of dt-bindings examples for protocol@13 to promote new bindings and simplification of scmi_devm_notifier_unregister * tag 'scmi-updates-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: pinctrl: Implementation of the generic scmi-pinctrl driver firmware: arm_scmi: Add basic support for SCMI v3.2 pincontrol protocol dt-bindings: firmware: Support SCMI pinctrl protocol firmware: arm_scmi: Introduce get_max_msg_size() helper/accessor firmware: arm_scmi: Add support for multiple vendors custom protocols dt-bindings: firmware: arm,scmi: Update examples for protocol@13 firmware: arm_scmi: Avoid non-constant printk format strings firmware: arm_scmi: Use dev_err_probe to bail out firmware: arm_scmi: Simplify scmi_devm_notifier_unregister firmware: arm_scmi: Add message dump traces for bad and unexpected replies firmware: arm_scmi: Add helper to trace bad messages include: trace: Widen the tag buffer in trace_scmi_dump_msg firmware: arm_scmi: Log the perf domain names in the error paths Link: https://lore.kernel.org/r/20240426105031.1526987-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.10 The Qualcomm SCM driver initialization order is improved, to avoid any potential for a client to find a half-initialized SCM instance. The handling of download mode bits is updated to not attempt QCOM_SCM_BOOT_SET_DLOAD_MODE if a io-address for the update is specified, and that path is changed to perform a read-modify-write to avoid updating unrelated bits. Error handling is corrected in the peripheral authentication service (PAS) functions, to release interconnect bandwidth votes in the case of an error. An unwanted error print on allocation error is also removed from this code path. The QSEECOM allow list is marked __maybe_unused to avoid build warnings when built with !OF. The error handling related to the interconnect API is cleaned up to avoid handling the impossible IS_ERR() condition. initcall level is bumped to "core" for cmd-db and rpmh-rsc, as dependent drivers like regulators, interconnects and clocks are registered at this level. Another attempt is made to remove the strncpy() usage in cmd-db, this time with strtomem_pad() which has the correct characteristics. The bwmon regmap cache is changed to maple tree. After an attempt to add missing MODULE_DEVICE_TABLEs to debug drivers, the intention of not having them automatically load is documented. Operations on the pmic_glink client list is put under mutual exclusion, to avoid races when clients are being registered. pmic_glink client registered after the firmware notification arrived was not informed that the firmware was up, this is resolved. More DSPs and the apss subsystem is added to the Qualcomm sleep stats driver. Checks for in-flight regulator requests in the RPMh RSC driver is improved to deal with the fact that these occupy multiple registers, so it's insufficient to just to direct address comparison. The socinfo drivers learns about X1 Elite and SMB2360 PMIC. The maintainers entry is split between the linux-arm-msm list and subset that is maintained in the qcom-soc tree, to avoid some confusion about maintainership. * tag 'qcom-drivers-for-6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (21 commits) soc: qcom: cmd-db: replace deprecated strncpy with strtomem soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request firmware: qcom: scm: Modify only the download bits in TCSR register firmware: qcom: scm: Fix __scm and waitq completion variable initialization firmware: qcom: scm: Rework dload mode availability check firmware: qcom: scm: Remove redundant scm argument from qcom_scm_waitq_wakeup() firmware: qcom: scm: Remove log reporting memory allocation failure soc: qcom: pmic_glink: notify clients about the current state soc: qcom: pmic_glink: don't traverse clients list without a lock soc: qcom: mention intentionally broken module autoloading firmware: qcom: qcm: fix unused qcom_scm_qseecom_allowlist MAINTAINERS: Split Qualcomm SoC and linux-arm-msm entries soc: qcom: qcom_stats: Add DSPs and apss subsystem stats dt-bindings: soc: qcom: qcom,pmic-glink: document QCM6490 compatible soc: qcom: socinfo: Add SMB2360 PMIC soc: qcom: socinfo: Add X1E80100 SoC ID table entry dt-bindings: arm: qcom,ids: Add SoC ID for X1E80100 soc: qcom: Update init level to core_initcall() for cmd-db and rpmh-rsc soc: qcom: icc-bwmon: Convert to use maple tree register cache firmware: qcom_scm: remove IS_ERR() checks from qcom_scm_bw_{en,dis}able() ...

Commit 50e782a86c98 ("efi/unaccepted: Fix soft lockups caused by parallel memory acceptance") has released the spinlock so other CPUs can do memory acceptance in parallel and not triggers softlockup on other CPUs. However the softlock up was intermittent shown up if the memory of the TD guest is large, and the timeout of softlockup is set to 1 second: RIP: 0010:_raw_spin_unlock_irqrestore Call Trace: ? __hrtimer_run_queues <IRQ> ? hrtimer_interrupt ? watchdog_timer_fn ? __sysvec_apic_timer_interrupt ? __pfx_watchdog_timer_fn ? sysvec_apic_timer_interrupt </IRQ> ? __hrtimer_run_queues <TASK> ? hrtimer_interrupt ? asm_sysvec_apic_timer_interrupt ? _raw_spin_unlock_irqrestore ? __sysvec_apic_timer_interrupt ? sysvec_apic_timer_interrupt accept_memory try_to_accept_memory do_huge_pmd_anonymous_page get_page_from_freelist __handle_mm_fault __alloc_pages __folio_alloc ? __tdx_hypercall handle_mm_fault vma_alloc_folio do_user_addr_fault do_huge_pmd_anonymous_page exc_page_fault ? __do_huge_pmd_anonymous_page asm_exc_page_fault __handle_mm_fault When the local irq is enabled at the end of accept_memory(), the softlockup detects that the watchdog on single CPU has not been fed for a while. That is to say, even other CPUs will not be blocked by spinlock, the current CPU might be stunk with local irq disabled for a while, which hurts not only nmi watchdog but also softlockup. Chao Gao pointed out that the memory accept could be time costly and there was similar report before. Thus to avoid any softlocup detection during this stage, give the softlockup a flag to skip the timeout check at the end of accept_memory(), by invoking touch_softlockup_watchdog().

2024-04-18firmware: arm_ffa: Fix kernel warning about incorrect SRI/NPISudeep Holla1-0/+2
If the firmware returns incorrect SRI/NRI number, we fail to set it up in the kernel which is absolutely fine. However, we don't reset the stashed value of sched_recv or notif_pend IRQs. When we call ffa_notifications_cleanup() in case of failures to setup the notifications, we end up calling free_percpu_irq() from ffa_uninit_pcpu_irq() which results in the following warning: | genirq: Flags mismatch irq 6. 00004401 (ARM-FFA-NPI) vs. 00004400 (IPI) | ARM FF-A: Error registering percpu NPI nIRQ 6 : -16 | ARM FF-A: Notification setup failed -16, not enabled | ------------[ cut here ]------------ | Trying to free already-free IRQ 6 | WARNING: CPU: 2 PID: 1 at kernel/irq/manage.c:2476 __free_percpu_irq+0x6c/0x138 | Modules linked in: | CPU: 2 PID: 1 Comm: swapper/0 Not tainted 6.9.0-rc3 #211 | Hardware name: FVP Base RevC (DT) | pstate: 614000c9 (nZCv daIF +PAN -UAO -TCO +DIT -SSBS BTYPE=--) | pc : __free_percpu_irq+0x6c/0x138 | lr : __free_percpu_irq+0x6c/0x138 | Call trace: | __free_percpu_irq+0x6c/0x138 | free_percpu_irq+0x48/0x84 | ffa_notifications_cleanup+0x78/0x164 | ffa_notifications_setup+0x368/0x3c0 | ffa_init+0x2b4/0x36c | do_one_initcall+0xe0/0x258 | do_initcall_level+0x8c/0xac | do_initcalls+0x54/0x94 | do_basic_setup+0x1c/0x28 | kernel_init_freeable+0x108/0x174 | kernel_init+0x20/0x1a4 | ret_from_fork+0x10/0x20 Fix the same by resetting the stashed copy of IRQ values to 0 in case of any failure to set them up properly.

2024-04-18firmware: arm_scmi: Add support for multiple vendors custom protocolsCristian Marussi2-22/+162
Add a mechanism to be able to tag vendor protocol modules at compile-time with a vendor/sub_vendor string and an implementation version and then to choose to load, at run-time, only those vendor protocol modules matching as close as possible the vendor/subvendor identification advertised by the SCMI platform server. In this way, any in-tree existent vendor protocol module can be build and shipped by default in a single kernel image, even when using the same clashing protocol identification numbers, since the SCMI core will take care at run-time to load only the ones pertinent to the running system.

2024-04-15firmware: arm_ffa: Add support for handling notification pending interrupt(NPI)Jens Wiklander1-16/+55
The FF-A uses the notification pending interrupt to inform the receiver that it has a pending notification. This is a virtual interrupt and is used by the following type of receivers: 1. A guest/VM running under a hypervisor. 2. An S-EL1 SP running under a S-EL2 SPMC. The rules that govern the properties of the NPI are the same as the rules for the SRI with couple of exceptions. Both SRI and NPI can be supported simultaneously. The handling of NPI is also same as the handling of notification for the self/primary VM with ID 0 except the absence of global notification.

In preparation to support handling of Notification Pending Interrupt(NPI) in addition to the existing support for Schedule Receiver Interrupt(SRI), refactor the code around SRI handling so that NPI support can reuse some of it. This change shouldn't have any functionality impact. It neither adds the support for NPIs nor changes any SRI support.

2024-04-15firmware: arm_ffa: Skip creation of the notification bitmapsJens Wiklander1-9/+7
When the FF-A driver is running inside a guest VM under an hypervisor, the driver/guest VM doesn't have the permission/capability to request the creation of notification bitmaps. For a VM, the hypervisor reserves memory for its VM and hypervisor framework notification bitmaps and the SPMC reserves memory for its SP and SPMC framework notification bitmaps before the hypervisor initializes it. The hypervisor does not initialize a VM if memory cannot be reserved for all its notification bitmaps. So the creation of all the necessary bitmaps are already done when the driver initialises and hence it can be skipped. We rely on FFA_FEATURES(FFA_NOTIFICATION_BITMAP_CREATE) to fail when running in the guest to handle this in the driver.

2024-04-13efi: Clear up misconceptions about a maximum variable name sizeTim Schumacher1-1/+1
The UEFI specification does not make any mention of a maximum variable name size, so the headers and implementation shouldn't claim that one exists either. Comments referring to this limit have been removed or rewritten, as this is an implementation detail local to the Linux kernel. Where appropriate, the magic value of 1024 has been replaced with EFI_VAR_NAME_LEN, as this is used for the efi_variable struct definition. This in itself does not change any behavior, but should serve as points of interest when making future changes in the same area. A related build-time check has been added to ensure that the special 512 byte sized buffer will not overflow with a potentially decreased EFI_VAR_NAME_LEN.

2024-04-09firmware: ti_sci: Unconditionally register reset handlerAndrew Davis1-11/+4
There was once a limitation that there could only be one system reset handler. Due to that we only would register this handler when a non-standard device tree property was found, else we left the default handler in place (usually PSCI). Now that we can have multiple handlers, and TI-SCI reset is always available in the firmware, register this handler unconditionally. This priority is left at the default so higher priority handlers (like PSCI) are still attempted first.

2024-04-09firmware: qcom: uefisecapp: Fix memory related IO errors and crashesMaximilian Luz2-77/+97
It turns out that while the QSEECOM APP_SEND command has specific fields for request and response buffers, uefisecapp expects them both to be in a single memory region. Failure to adhere to this has (so far) resulted in either no response being written to the response buffer (causing an EIO to be emitted down the line), the SCM call to fail with EINVAL (i.e., directly from TZ/firmware), or the device to be hard-reset. While this issue can be triggered deterministically, in the current form it seems to happen rather sporadically (which is why it has gone unnoticed during earlier testing). This is likely due to the two kzalloc() calls (for request and response) being directly after each other. Which means that those likely return consecutive regions most of the time, especially when not much else is going on in the system. Fix this by allocating a single memory region for both request and response buffers, properly aligning both structs inside it. This unfortunately also means that the qcom_scm_qseecom_app_send() interface needs to be restructured, as it should no longer map the DMA regions separately. Therefore, move the responsibility of DMA allocation (or mapping) to the caller.
