2022-12-07mfd: tps65219: Add driver for TI TPS65219 PMICJerome Neanne1-0/+345
The TPS65219 is a power management IC PMIC designed to supply a wide range of SoCs in both portable and stationary applications. Any SoC can control TPS65219 over a standard I2C interface. It contains the following components: - Regulators. - Over Temperature warning and Shut down. - GPIOs - Multi Function Pins (MFP) - power-button This patch adds support for tps65219 PMIC. At this time only the functionalities listed below are made available: - Regulators probe and functionalities - warm and cold reset support - SW shutdown support - Regulator warnings via IRQs - Power-button via IRQ Signed-off-by: Jerome Neanne <jneanne@baylibre.com> Signed-off-by: Markus Schneider-Pargmann <msp@baylibre.com> Signed-off-by: Lee Jones <lee@kernel.org> Link: https://lore.kernel.org/r/20221104152311.1098603-5-jneanne@baylibre.com
2022-12-07mfd: stmfx: Remove #ifdef guards for PM related functionsPaul Cercueil1-2/+0
Use the new DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.

2022-11-18Input: max8997 - convert to modern way to get a reference to a PWMUwe Kleine-König1-3/+0
pwm_request() isn't recommended to be used any more because it relies on global IDs for the PWM which comes with different difficulties. The new way to do things is to find the right PWM using a reference from the platform device. (This can be created either using a device-tree or a platform lookup table, see e.g. commit 5a4412d4a82f ("ARM: pxa: tavorevb: Use PWM lookup table") how to do this.) There are no in-tree users, so there are no other code locations that need adaption.

2022-09-09mfd: ocelot: Add helper to get regmap from a resourceColin Foster1-0/+62
Several ocelot-related modules are designed for MMIO / regmaps. As such, they often use a combination of devm_platform_get_and_ioremap_resource() and devm_regmap_init_mmio(). Operating in an MFD might be different, in that it could be memory mapped, or it could be SPI, I2C... In these cases a fallback to use IORESOURCE_REG instead of IORESOURCE_MEM becomes necessary. When this happens, there's redundant logic that needs to be implemented in every driver. In order to avoid this redundancy, utilize a single function that, if the MFD scenario is enabled, will perform this fallback logic.

In BCM2711 the new RPiVid ASB took over V3D. The old ASB is still present with the ISP and H264 bits, and V3D is in the same place in the new ASB as the old one. As per the devicetree bindings, BCM2711 will provide both the old and new ASB resources, so get both of them and pass them into 'bcm2835-power,' which will take care of selecting which one to use accordingly. Since the RPiVid ASB's resources were being provided prior to formalizing the bindings[1], also support the old DT files that didn't use 'reg-names.'

2022-05-07ARM/pxa/mfd/power/sound: Switch Tosa to GPIO descriptorsLinus Walleij1-3/+0
The Tosa device (Sharp SL-6000) has a mishmash driver set-up for the Toshiba TC6393xb MFD that includes a battery charger and touchscreen and has some kind of relationship to the SoC sound driver for the AC97 codec. Other devices define a chip like this but seem only half-implemented, not really handling battery charging etc. This patch switches the Toshiba MFD device to provide GPIO descriptors to the battery charger and SoC codec. As a result some descriptors need to be moved out of the Tosa boardfile and new one added: all SoC GPIO resources to these drivers now comes from the main boardfile, while the MFD provide GPIOs for its portions. As a result we can request one GPIO from our own GPIO chip and drop two hairy callbacks into the board file. This platform badly needs to have its drivers split up and converted to device tree probing to handle this quite complex relationship in an orderly manner. I just do my best in solving the GPIO descriptor part of the puzzle. Please don't ask me to fix everything that is wrong with these driver to todays standards, I am just trying to fix one aspect. I do try to use modern devres resource management and handle deferred probe using new functions where appropriate.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "The sprinkling of SPI drivers is because we added a new one and Mark sent us a SPI driver interface conversion pull request. Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules. - Add support for locked bridge ports (for 802.1X). - tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios. - IPv6 extension header handling in Open vSwitch. - Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port.
