pwm: aspeed: replace %pe in dev_err()

2026-01-02T21:51:54Z

Replace %pe with %d and adjust the argument accordingly in a dev_err() call in the pwm-aspeed driver. U-boot doesn't support the %pe format specifier. Likely it was copied from Linux. Signed-off-by: David Lechner Reviewed-by: Chia-Wei Wang

pwm: put all PWM DM drivers under an if condition on DM_PWM

2025-11-07T19:01:12Z

This simplifies the "depends on" since we don't need DM_PWM listed explicitly there as it already is made explicit via the surrounding "if". No intended change in behavior. Reviewed-by: Tom Rini Signed-off-by: Quentin Schulz

pwm: make sandbox depend on DM_PWM

2025-11-07T19:01:12Z

Since it is registered as a U_CLASS_DRIVER, Sandbox PWM driver is a Driver Model Driver and thus to be usable depends on DM_PWM to be selected. Let's make sure of that via the appropriate Kconfig option. Signed-off-by: Quentin Schulz

pwm: move all PWM related topics inside a Kconfig menu

2025-11-07T19:01:12Z

So it's visually better split from the other subsystems when using menuconfig. Reviewed-by: Tom Rini Signed-off-by: Quentin Schulz

pwm: cadence-ttc: Insufficient elements in array

2025-10-09T07:07:03Z

The Cadence TTC has 3 channels that can each be used for PWM functions. Ensure that the array has sufficient elements to avoid a possible memory access overrun. Use a macro to keep the array size and limit checks in sync so adjust checks to work with this. This issue was found by Smatch.

pwm: meson: Stop premature exit from for loop

2025-09-30T18:32:15Z

In meson_pwm_probe the for loop attempts to get the name of a clock but the following if..else statements only perform useful work if -ENODATA is returned from clk_get_by_name. If clk_get_by_name simply succeeds then this results in a premature exit from the for loop and the following code can never be reached. Make the else clause only apply for an error return from clk_get_by_name. This issue was found by Smatch.

pwm: pwm-aspeed: Add missing to pwm-aspeed.c

This driver references the logarithmic macros while relying on an indirection inclusion of . Add the missing include directly. Signed-off-by: Tom Rini

pwm: Tighten some pwm driver dependencies

2025-08-14T16:59:05Z

A few pwm drivers cannot build without access to some platform specific header files. Express those requirements in Kconfig as well. Signed-off-by: Tom Rini

pwm: stm32: add support for stm32mp25
