2021-12-16pwm: tegra: Add runtime PM and OPP supportDmitry Osipenko
The PWM on Tegra belongs to the core power domain and we're going to enable GENPD support for the core domain. Now PWM must be resumed using runtime PM API in order to initialize the PWM power state. The PWM clock rate must be changed using OPP API that will reconfigure the power domain performance state in accordance to the rate. Add runtime PM and OPP support to the PWM driver.

2021-11-05pwm: pwm-samsung: Trigger manual update when disabling PWMMårten Lindahl
When duty-cycle is at full level (100%), the TCNTn and TCMPn registers needs to be flushed in order to disable the signal. The PWM manual does not say anything about this, but states that only clearing the TCON auto-reload bit should be needed, and this seems to be true when the PWM duty-cycle is not at full level. This can be observed on an Axis ARTPEC-8, by running: echo <period> > pwm/period echo <period> > pwm/duty_cycle echo 1 > pwm/enable echo 0 > pwm/enable Since the TCNTn and TCMPn registers are activated when enabling the PWM (setting TCON auto-reload bit), and are not touched when disabling the PWM, the double buffered auto-reload function seems to be still active. Lowering duty-cycle, and restoring it again in between the enabling and disabling, makes the disable work since it triggers a reload of the TCNTn and TCMPn registers. Fix this by securing a reload of the TCNTn and TCMPn registers when disabling the PWM and having a full duty-cycle.

2021-11-05pwm: Make it explicit that pwm_apply_state() might sleepUwe Kleine-König
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.

2021-10-27pwm: Introduce single-PWM of_xlate functionBjorn Andersson
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.
