2024-07-10pwm: Add GPIO PWM driverVincent Whitchurch
Add a software PWM which toggles a GPIO from a high-resolution timer. This will naturally not be as accurate or as efficient as a hardware PWM, but it is useful in some cases. I have for example used it for evaluating LED brightness handling (via leds-pwm) on a board where the LED was just hooked up to a GPIO, and for a simple verification of the timer frequency on another platform. Since high-resolution timers are used, sleeping GPIO chips are not supported and are rejected in the probe function.

2024-07-10pwm: cros-ec: Simplify device tree xlationUwe Kleine-König
The cros-ec device tree binding only uses #pwm-cells = <1>, and so there is no period provided in the device tree. Up to now this was handled by hardcoding the period to the only supported value in the custom xlate callback. Apart from that, the default xlate callback (i.e. of_pwm_xlate_with_flags()) handles this just fine (and better, e.g. by checking args->args_count >= 1 before accessing args->args[0]). To simplify make use of of_pwm_xlate_with_flags(), drop the custom callback and provide the default period in .probe() already. Apart from simplifying the driver this also drops the last non-core user of pwm_request_from_chip() and so makes further simplifications possible.

2024-07-10pwm: atmel-tcb: Fix race condition and convert to guardsUwe Kleine-König
The hardware only supports a single period length for both PWM outputs. So atmel_tcb_pwm_config() checks the configuration of the other output if it's compatible with the currently requested setting. The register values are then actually updated in atmel_tcb_pwm_enable(). To make this race free the lock must be held during the whole process, so grab the lock in .apply() instead of individually in atmel_tcb_pwm_disable() and atmel_tcb_pwm_enable() which then also covers atmel_tcb_pwm_config(). To simplify handling, use the guard helper to let the compiler care for unlocking. Otherwise unlocking would be more difficult as there is more than one exit path in atmel_tcb_pwm_apply().

2024-07-10drm/amdgpu: timely save bad pages to eeprom after gpu ras reset is completedYiPeng Chai
The problem case is as follows: 1. GPU A triggers a gpu ras reset, and GPU A drives GPU B to also perform a gpu ras reset. 2. After gpu B ras reset started, gpu B queried a DE data. Since the DE data was queried in the ras reset thread instead of the page retirement thread, bad page retirement work would not be triggered. Then even if all gpu resets are completed, the bad pages will be cached in RAM until GPU B's bad page retirement work is triggered again and then saved to eeprom. This patch can save the bad pages to eeprom in time after gpu ras reset is completed. v2: 1. Add the above description to code comments. 2. Reuse existing function.

2024-07-10drm/amd/pm: Ignore initial value in smu response registerDanijel Slivka
Why: If the reg mmMP1_SMN_C2PMSG_90 is being written to during amdgpu driver load or driver unload, subsequent amdgpu driver load will fail at smu_hw_init. The default of mmMP1_SMN_C2PMSG_90 register at a clean environment is 0x1 and if value differs from expected, amdgpu driver load will fail. How to fix: Ignore the initial value in smu response register before the first smu message is sent,if smc in SMU_FW_INIT state, just proceed further to send the message. If register holds an unexpected value after smu message was sent set, smc_state to SMU_FW_HANG state and no further smu messages will be sent. v2: Set SMU_FW_INIT state at the start of smu hw_init/resume. Check smc_fw_state before sending smu message if in hang state skip sending message.

Unlike all the other 32-bit architectures, the time32 and stat64 sets of syscalls are not enabled on riscv32.

2024-07-10nios2: convert to generic syscall tableArnd Bergmann
The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. nios2 has one extra system call that gets added to scripts/syscall.tbl. The time32, stat64, and rlimit entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/nios2 got added but are no longer enabled by default for new architectures. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2024-07-10loongarch: convert to generic syscall tableArnd Bergmann
The uapi/asm/unistd_64.h and asm/syscall_table_64.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. Unlike the other architectures using the asm-generic header, loongarch uses none of the deprecated system calls at the moment. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2024-07-10hexagon: use new system call tableArnd Bergmann
The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. The time32, stat64, rlimit and renameat entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/hexagon got added but are no longer enabled by default for new architectures. As a side-effect, calling an unimplemented syscall now return -ENOSYS rather than branching into a NULL pointer. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2024-07-10csky: convert to generic syscall tableArnd Bergmann
The uapi/asm/unistd_32.h and asm/syscall_table_32.h headers can now be generated from scripts/syscall.tbl, which makes this consistent with the other architectures that have their own syscall.tbl. csky has two architecture specific system calls, which I add to the generic table. The time32, stat64 and rlimit entries in the syscall_abis_32 line are for system calls that were part of the generic ABI when arch/csky got added but are no longer enabled by default for new architectures. Both the user visible side of asm/unistd.h and the internal syscall table in the kernel should have the same effective contents after this. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
