2022-07-29pwm: twl-led: Document some limitations and link to the reference manualUwe Kleine-König1-0/+16
I found these just from reading the reference manual and the driver source. It's unclear to me if there are glitches when updating the ON and OFF registers. Signed-off-by: Uwe Kleine-König <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2022-05-20pwm: twl-led: Implement .apply() callbackUwe Kleine-König1-10/+66
To eventually get rid of all legacy drivers convert this driver to the modern world implementing .apply(). This just pushed a variant of pwm_apply_legacy() into the driver that was slightly simplified because the driver doesn't provide a .set_polarity() callback.

2021-09-02pwm: twl-led: Simplify using devm_pwmchip_add()Uwe Kleine-König1-16/+1
This allows to drop the platform_driver's remove function. This is the only user of driver data so this can go away, too. Signed-off-by: Uwe Kleine-König <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2021-03-22pwm: Always allocate PWM chip base ID dynamicallyUwe Kleine-König1-1/+0
Since commit 5e5da1e9fbee ("pwm: ab8500: Explicitly allocate pwm chip base dynamically") all drivers use dynamic ID allocation explicitly. New drivers are supposed to do the same, so remove support for driver specified base IDs and drop all assignments in the low-level drivers.

2017-01-04pwm: Remove .can_sleep from struct pwm_chipThierry Reding1-1/+0
All PWM devices have been marked as "might sleep" since v4.5, there is no longer a need to differentiate on a per-chip basis. Signed-off-by: Thierry Reding <[email protected]>

2012-11-28pwm: New driver to support PWM driven LEDs on TWL4030/6030 series of PMICsPeter Ujfalusi1-0/+344
The driver supports the following LED outputs as generic PWM driver: TWL4030 LEDA and LEDB (PWMA and PWMB) TWL6030 Charging indicator LED (PWM LED) On TWL6030 when the PWM requested LED is configured to be controlled by SW. In this case the user can enable/disable and set the duty period freely. When the PWM has been freed, the LED driver is put back to HW control.
