2021-11-16power: reset: ltc2952: Fix use of floating point literalsNathan Chancellor
A new commit in LLVM causes an error on the use of 'long double' when '-mno-x87' is used, which the kernel does through an alias, '-mno-80387' (see the LLVM commit below for more details around why it does this). drivers/power/reset/ltc2952-poweroff.c:162:28: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it data->wde_interval = 300L * 1E6L; ^ drivers/power/reset/ltc2952-poweroff.c:162:21: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it data->wde_interval = 300L * 1E6L; ^ drivers/power/reset/ltc2952-poweroff.c:163:41: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it data->trigger_delay = ktime_set(2, 500L*1E6L); ^ 3 errors generated. This happens due to the use of a 'long double' literal. The 'E6' part of '1E6L' causes the literal to be a 'double' then the 'L' suffix promotes it to 'long double'. There is no visible reason for floating point values in this driver, as the values are only assigned to integer types. Use NSEC_PER_MSEC, which is the same integer value as '1E6L', to avoid changing functionality but fix the error.

There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

2020-10-15power: reset: POWER_RESET_OCELOT_RESET should depend on Ocelot or Sparx5Geert Uytterhoeven
To add support for Sparx5, the dependency on MSCC_OCELOT was removed. However, this increases exposure of the driver question not only to Sparx5 platforms, but to everyone. Hence re-add the dependency on MSCC_OCELOT, and extend it with ARCH_SPARX5, to prevent asking the user about this driver when configuring a kernel without Ocelot and Sparx5 support.

2020-07-28power: reset: add driver for LinkStation power offDaniel González Cabanelas
Some Buffalo LinkStations perform the power off operation, at restart time, depending on the state of an output pin (LED2/INTn) at the ethernet PHY. This pin is also used to wake the machine when a WoL packet is received by the PHY. The driver is required by the Buffalo LinkStation LS421DE (ARM MVEBU), and other models. Without it, the board remains forever halted if a power off command is executed, unless the PSU is disconnected and connected again. Add the driver to provide the power off function and also make the WoL feature to be available.

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

Pull ARM SoC updates from Arnd Bergmann: "One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options" * tag 'arm-soc-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (94 commits) ARM: omap2: fix omap5_realtime_timer_init definition ARM: zynq: Don't select CONFIG_ICST ARM: OMAP2+: Fix regression for using local timer on non-SMP SoCs clk: versatile: Fix kconfig dependency on COMMON_CLK_VERSATILE ARM: davinci: fix build failure without I2C power: reset: vexpress: fix build issue power: vexpress: cleanup: use builtin_platform_driver power: vexpress: add suppress_bind_attrs to true Revert "ARM: vexpress: Don't select VEXPRESS_CONFIG" MAINTAINERS: pxa: remove Compulab arm/pxa support ARM: pxa: remove Compulab pxa2xx boards bus: arm-integrator-lm: Fix return value check in integrator_ap_lm_probe() soc: imx: move cpu code to drivers/soc/imx ARM: imx: move cpu definitions into a header ARM: imx: use device_initcall for imx_soc_device_init ARM: imx: pcm037: make pcm970_sja1000_platform_data static bus: ti-sysc: Timers no longer need legacy quirk handling ARM: OMAP2+: Drop old timer code for dmtimer and 32k counter ARM: dts: Configure system timers for omap2 ARM: dts: Configure system timers for ti81xx ...
