pwm: Rename pwm_apply_state() to pwm_apply_might_sleep() In order to introduce a pwm api which can be used from atomic context, we will need two functions for applying pwm changes: int pwm_apply_might_sleep(struct pwm *, struct pwm_state *); int pwm_apply_atomic(struct pwm *, struct pwm_state *); This commit just deals with renaming pwm_apply_state(), a following commit will introduce the pwm_apply_atomic() function.

Input: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Input: pwm-vibra - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.

Input: pwm-vibra - stop regulator after disabling pwm, not before This patch fixes order of disable calls in pwm_vibrator_stop. Currently when starting device, we first enable vcc regulator and then setup and enable pwm. When stopping, we should do this in oposite order, so first disable pwm and then disable regulator. Previously order was the same as in start. Signed-off-by: Paweł Chmiel <pawel.mikolaj.chmiel@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
