Pull ARM fix from Russell King: "Resolve a Keystone 2 kernel mapping regression" * tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 9104/2: Fix Keystone 2 kernel mapping regression
2021-08-13ARM: ixp4xx: fix building both pci driversArnd Bergmann1-24/+24
When both the old and the new PCI drivers are enabled in the same kernel, there are a couple of namespace conflicts that cause a build failure: drivers/pci/controller/pci-ixp4xx.c:38: error: "IXP4XX_PCI_CSR" redefined [-Werror] 38 | #define IXP4XX_PCI_CSR 0x1c | In file included from arch/arm/mach-ixp4xx/include/mach/hardware.h:23, from arch/arm/mach-ixp4xx/include/mach/io.h:15, from arch/arm/include/asm/io.h:198, from include/linux/io.h:13, from drivers/pci/controller/pci-ixp4xx.c:20: arch/arm/mach-ixp4xx/include/mach/ixp4xx-regs.h:221: note: this is the location of the previous definition 221 | #define IXP4XX_PCI_CSR(x) ((volatile u32 *)(IXP4XX_PCI_CFG_BASE_VIRT+(x))) | drivers/pci/controller/pci-ixp4xx.c:148:12: error: 'ixp4xx_pci_read' redeclared as different kind of symbol 148 | static int ixp4xx_pci_read(struct ixp4xx_pci *p, u32 addr, u32 cmd, u32 *data) | ^~~~~~~~~~~~~~~ Rename both the ixp4xx_pci_read/ixp4xx_pci_write functions and the IXP4XX_PCI_CSR macro.

2021-08-10ARM: 9104/2: Fix Keystone 2 kernel mapping regressionLinus Walleij4-8/+27
This fixes a Keystone 2 regression discovered as a side effect of defining an passing the physical start/end sections of the kernel to the MMU remapping code. As the Keystone applies an offset to all physical addresses, including those identified and patches by phys2virt, we fail to account for this offset in the kernel_sec_start and kernel_sec_end variables. Further these offsets can extend into the 64bit range on LPAE systems such as the Keystone 2. Fix it like this: - Extend kernel_sec_start and kernel_sec_end to be 64bit - Add the offset also to kernel_sec_start and kernel_sec_end As passing kernel_sec_start and kernel_sec_end as 64bit invariably incurs BE8 endianness issues I have attempted to dry-code around these. Tested on the Vexpress QEMU model both with and without LPAE enabled.

2021-07-30ARM: dts: stm32: Fix touchscreen IRQ line assignment on DHCOMMarek Vasut1-10/+14
While 7e5f3155dcbb4 ("ARM: dts: stm32: Fix LED5 on STM32MP1 DHCOM PDK2") fixed the LED0 assignment on the PDK2 board, the same commit did not update the touchscreen IRQ line assignment, which is the same GPIO line, shared between the LED0 output and touchscreen IRQ input. To make this more convoluted, the same EXTI input (not the same GPIO line) is shared between Button B which is Active-Low IRQ, and touchscreen IRQ which is Edge-Falling IRQ, which cannot be used at the same time. In case the LCD board with touchscreen is in use, which is the case here, LED0 must be disabled, Button B must be polled, so the touchscreen interrupt works as it should. Update the touchscreen IRQ line assignment, disable LED0 and use polled GPIO button driver for Button B, since the DT here describes baseboard with LCD board.

There are multiple accounts of this in the SMSC PHY driver patches which attempted to make EDPD reliable, however it seems there is always some sort of corner case left. Unfortunatelly, there is no errata documented which would confirm this to be a silicon bug on the LAN87xx series of PHYs (LAN8700, LAN8710, LAN8720 at least). Disable EDPD on the DHCOM SoM, just like multiple other boards already do as well, to make the cable detection reliable.

2021-07-30ARM: dts: stm32: Prefer HW RTC on DHCOM SoMMarek Vasut1-1/+3
The DHCOM SoM has two RTC, one is the STM32 RTC built into the SoC and another is Microcrystal RV RTC. By default, only the later has battery backup, the former does not. The order in which the RTCs are probed on boot is random, which means the kernel might pick up system time from the STM32 RTC which has no battery backup. This then leads to incorrect initial system time setup, even though the HW RTC has correct time configured in it. Add DT alias entries, so that the RTCs get assigned fixed IDs and the HW RTC is always picked by the kernel as the default RTC, thus resulting in correct system time in early userspace.

2021-07-29bpf: Introduce BPF nospec instruction for mitigating Spectre v4Daniel Borkmann1-0/+3
In case of JITs, each of the JIT backends compiles the BPF nospec instruction /either/ to a machine instruction which emits a speculation barrier /or/ to /no/ machine instruction in case the underlying architecture is not affected by Speculative Store Bypass or has different mitigations in place already. This covers both x86 and (implicitly) arm64: In case of x86, we use 'lfence' instruction for mitigation. In case of arm64, we rely on the firmware mitigation as controlled via the ssbd kernel parameter. Whenever the mitigation is enabled, it works for all of the kernel code with no need to provide any additional instructions here (hence only comment in arm64 JIT). Other archs can follow as needed. The BPF nospec instruction is specifically targeting Spectre v4 since i) we don't use a serialization barrier for the Spectre v1 case, and ii) mitigation instructions for v1 and v4 might be different on some archs. The BPF nospec is required for a future commit, where the BPF verifier does annotate intermediate BPF programs with speculation barriers.

2021-07-27omap5-board-common: remove not physically existing vdds_1v8_main fixed-regulatorH. Nikolaus Schaller1-8/+1
This device tree include file describes a fixed-regulator connecting smps7_reg output (1.8V) to some 1.8V rail and consumers (vdds_1v8_main). This regulator does not physically exist. I assume it was introduced as a wrapper around smps7_reg to provide a speaking signal name "vdds_1v8_main" as label. This fixed-regulator without real function was not an issue in driver code until Commit 98e48cd9283d ("regulator: core: resolve supply for boot-on/always-on regulators") introduced a new check for regulator initialization which makes Palmas regulator registration fail: [ 5.407712] ldo1: supplied by vsys_cobra [ 5.412748] ldo2: supplied by vsys_cobra [ 5.417603] palmas-pmic 48070000.i2c:palmas@48:palmas_pmic: failed to register 48070000.i2c:palmas@48:palmas_pmic regulator The reason is that the supply-chain of regulators is too long and goes from ldo3 through the virtual vdds_1v8_main regulator and then back to smps7. This adds a cross-dependency of probing Palmas regulators and the fixed-regulator which leads to probe deferral by the new check and is no longer resolved. Since we do not control what device tree files including this one reference (either &vdds_1v8_main or &smps7_reg or both) we keep both labels for smps7 for compatibility.

2021-07-27ARM: dts: am43x-epos-evm: Reduce i2c0 bus speed for tps65218Dave Gerlach1-1/+1
Based on the latest timing specifications for the TPS65218 from the data sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206 from November 2014, we must change the i2c bus speed to better fit within the minimum high SCL time required for proper i2c transfer. When running at 400khz, measurements show that SCL spends 0.8125 uS/1.666 uS high/low which violates the requirement for minimum high period of SCL provided in datasheet Table 7.6 which is 1 uS. Switching to 100khz gives us 5 uS/5 uS high/low which both fall above the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low. Without this patch occasionally a voltage set operation from the kernel will appear to have worked but the actual voltage reflected on the PMIC will not have updated, causing problems especially with cpufreq that may update to a higher OPP without actually raising the voltage on DCDC2, leading to a hang.

The AR803x PHY used on this modules seems to require the reset line to be asserted for around 10ms in order to avoid rare cases where the PHY gets stuck in an incoherent state that prevents it to function correctly. The previous value of 2ms was found to be problematic on some setups, causing intermittent issues where the PHY would be unresponsive every once in a while on some sytems, with a low occurrence (it typically took around 30 consecutive reboots to encounter the issue). Bumping the delay to the 10ms makes the issue dissapear, with more than 2500 consecutive reboots performed without the issue showing-up.

Also some updates/cleanup of platform data. - Core power domain support for Tegra platforms, and some improvements in build test coverage by adding stubs for compile test targets. - A handful of updates to i.MX platforms, adding legacy (non-PSCI) SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform data and board fixups for iMX6/7. ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner, Rockchip" * tag 'arm-soc-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (53 commits) MAINTAINERS: Add myself as TEE subsystem reviewer ixp4xx: fix spelling mistake in Kconfig "Devce" -> "Device" hw_random: ixp4xx: Add OF support hw_random: ixp4xx: Add DT bindings hw_random: ixp4xx: Turn into a module hw_random: ixp4xx: Use SPDX license tag hw_random: ixp4xx: enable compile-testing pata: ixp4xx: split platform data to its own header soc: ixp4xx: move cpu detection to linux/soc/ixp4xx/cpu.h PCI: ixp4xx: Add a new driver for IXP4xx PCI: ixp4xx: Add device tree bindings for IXP4xx ARM/ixp4xx: Make NEED_MACH_IO_H optional ARM/ixp4xx: Move the virtual IObases MAINTAINERS: ARM/MStar/Sigmastar SoCs: Add a link to the MStar tree ARM: debug: add UART early console support for MSTAR SoCs ARM: dts: ux500: Fix LED probing ARM: imx: add smp support for imx7d ARM: imx6q: drop of_platform_default_populate() from init_machine arm64: dts: rockchip: Update RK3399 PCI host bridge window to 32-bit address memory soc/tegra: fuse: Fix Tegra234-only builds ...

git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock Pull memblock fix from Mike Rapoport: "This is a fix for the rework of ARM's pfn_valid() implementation merged during this merge window. Don't abuse pfn_valid() to check if pfn is in RAM The semantics of pfn_valid() is to check presence of the memory map for a PFN and not whether a PFN is in RAM. The memory map may be present for a hole in the physical memory and if such hole corresponds to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and fail. Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN is in RAM or not" * tag 'fixes-2021-07-09' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock: arm: ioremap: don't abuse pfn_valid() to check if pfn is in RAM
