pwm: Drop unused forward declaration from pwm.h

2022-06-22T13:35:13+00:00

The declaration was necessary until commit cc2d22477779 ("pwm: Drop
per-chip dbg_show callback").

pwm: Reorder header file to get rid of struct pwm_capture forward declaration

2022-06-22T13:33:54+00:00

There is no cyclic dependency, so by reordering the forward declaration
can be dropped.

pwm: Drop support for legacy drivers

2022-06-22T13:31:13+00:00

There are no drivers left providing the legacy callbacks. So drop
support for these.

If this commit breaks your out-of-tree pwm driver, look at e.g. commit
ec00cd5e63f0 ("pwm: renesas-tpu: Implement .apply() callback") for an
example of the needed conversion for your driver.

pwm: Make it explicit that pwm_apply_state() might sleep

2021-11-05T10:51:41+00:00

At least some implementations sleep. So mark pwm_apply_state() with a
might_sleep() to make callers aware. In the worst case this uncovers a
valid atomic user, then we revert this patch and at least gained some more
knowledge and then can work on a concept similar to
gpio_get_value/gpio_get_value_cansleep.

pwm: Add might_sleep() annotations for !CONFIG_PWM API functions

2021-11-05T10:51:40+00:00

The normal implementations of these functions make use of mutexes. To
make it obvious that these functions might sleep also add annotations to
the dummy implementations in the !CONFIG_PWM case.

pwm: Introduce single-PWM of_xlate function

2021-10-27T15:02:33+00:00

The existing pxa driver and the upcoming addition of PWM support in the
TI sn565dsi86 DSI/eDP bridge driver both has a single PWM channel and
thereby a need for a of_xlate function with the period as its single
argument.

Introduce a common helper function in the core that can be used as
of_xlate by such drivers and migrate the pxa driver to use this.

pwm: Make pwmchip_remove() return void

2021-09-02T19:38:56+00:00

Since some time pwmchip_remove() always returns 0 so the return value
isn't usefull. Now that all callers are converted to ignore its value
the function can be changed to return void.

pwm: core: Remove unused devm_pwm_put()

2021-06-30T17:12:19+00:00

There are no users and seems no will come of the devm_pwm_put().
Remove the function.

While at it, slightly update documentation.

pwm: Add a device-managed function to add PWM chips

This potentially simplifies low-level PWM drivers.
