* ARM: 9263/1: use .arch directives instead of assembler command line flagsNick Desaulniers2022-11-085-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assembler directives instead of assembler arguments"). GCC and GNU binutils support setting the "sub arch" via -march=, -Wa,-march, target function attribute, and .arch assembler directive. Clang was missing support for -Wa,-march=, but this was implemented in clang-13. The behavior of both GCC and Clang is to prefer -Wa,-march= over -march= for assembler and assembler-with-cpp sources, but Clang will warn about the -march= being unused. clang: warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] Since most assembler is non-conditionally assembled with one sub arch (modulo arch/arm/delay-loop.S which conditionally is assembled as armv4 based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the .arch assembler directive. Add a few more instances found in compile testing as found by Arnd and Nathan.

This fixes a storm of warnings once LP2 idling state is enabled on Tegra30. The outer_disable() helper has sanity checks for interrupts and secondary CPUs being disabled and we are pretty confident about the interrupts state during of CPU idling / system suspend. The rail-off status check is added in this patch as equivalent for the "num_online_cpus() > 1".

* ARM: tegra: Remove pen-locking from cpuidle-tegra20Dmitry Osipenko2020-03-127-251/+4
| | | | | | | | | | | | | | | | | | | | | | | Pen-locking is meant to block CPU0 if CPU1 wakes up during of entering into LP2 because of some interrupt firing up, preventing unnecessary LP2 enter that will be resumed immediately. Apparently this case doesn't happen often in practice, I checked how often it takes place and found that after ~20 hours of browsing web, managing email, watching videos and idling (15+ hours) there is only a dozen of early LP2 entering abortions and they all happened while device was idling. Thus let's remove the pen-locking and make LP2 entering uninterruptible, simplifying code quite a lot. This will also become very handy for the upcoming unified cpuidle driver, allowing to have a common LP2 code-path across of different hardware generations.

| | | | | | | | | | | | | | | | | The sleep-tegra*.S provides functionality required for suspend/resume and CPU hotplugging. The new unified CPUIDLE driver will support multiple hardware generations starting from Terga20 and ending with Tegra124, the driver will utilize functions that are provided by the assembly and thus it is cleaner to compile that code without any build-dependencies in order to avoid churning with #ifdef's.

* ARM: tegra: Use clk_m CPU on Tegra124 LP1 resumeStephen Warren2020-01-081-2/+6
| | | | | | | | | | | | | | Configure the clock controller to set an alternate clock for the CPU when it receives an IRQ during LP1 (system suspend). Specifically, use clk_m (the crystal) rather than clk_s (a 32KHz clock). Such an IRQ will be the LP1 wake event. This reduces the amount of time taken to resume from LP1. NVIDIA's downstream kernel executes this code on both Tegra30 and Tegra124, so it appears OK to make this change unconditionally.

* ARM: tegra: Modify reshift divider during LP1Stephen Warren2020-01-081-0/+11
| | | | | | | | | | | | | | | The reshift hardware module implements the RAM re-repair process. This module uses PLLP as an input clock during LP1 resume. The input divider for this clock is typically set for PLLP's normal rate. During LP1 resume, PLLP is bypassed and so runs at the crystal rate, which is much slower. Consequently, decrease the divider so that the reshift module runs at a reasonable rate during LP1 resume. NVIDIA's downstream kernel code only does this if not compiled for Tegra30, so the added code is made conditional upon the chip ID.

* ARM: tegra: Enable PLLP bypass during Tegra124 LP1Stephen Warren2020-01-081-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a little over a year, U-Boot has configured the flow controller to perform automatic RAM re-repair on off->on power transitions of the CPU rail[1]. This is mandatory for correct operation of Tegra124. However, RAM re-repair relies on certain clocks, which the kernel must enable and leave running. PLLP is one of those clocks. This clock is shut down during LP1 in order to save power. Enable bypass (which I believe routes osc_div_clk, essentially the crystal clock, to the PLL output) so that this clock signal toggles even though the PLL is not active. This is required so that LP1 power mode (system suspend) operates correctly. The bypass configuration must then be undone when resuming from LP1, so that all peripheral clocks run at the expected rate. Without this, many peripherals won't work correctly; for example, the UART baud rate would be incorrect. NVIDIA's downstream kernel code only does this if not compiled for Tegra30, so the added code is made conditional upon the chip ID. NVIDIA's downstream code makes this change conditional upon the active CPU cluster. The upstream kernel currently doesn't support cluster switching, so this patch doesn't test the active CPU cluster ID.

In this case, there is a need to manage clocks and power explicitly in the driver and reviewers were not really convinced about this. The consensus at the end was to enforce PM requirement to keep things simple, rather driver mentioning a dependency on PM. This is how it is done for ARM 64-bit Tegra platforms and the same can be done for 32-bit Tegra platforms too. Finally the objective is to remove dependency on PM availability for all Tegra drivers.
