2022-05-20pwm: stmpe: Implement .apply() callbackUwe Kleine-König1-3/+26
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.

2022-02-02pwm: stmpe: Rename variable pointing to driver private dataUwe Kleine-König1-8/+8
In all code locations but the probe function variables of type struct stmpe_pwm * are called "stmpe_pwm". Align the name used in stmpe_pwm_probe() accordingly. Still more as the current name "pwm" is usually reserved for variables of type struct pwm_device *.

2022-02-02pwm: stmpe: Drop unused setting of driver dataUwe Kleine-König1-2/+0
The driver never uses dev_get_drvdata() to retrieve the pwm driver data. So drop setting it. 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.

2016-07-11pwm: Add a driver for the STMPE PWMLinus Walleij1-0/+319
This adds a driver for the PWM block found in chips of the STMPE 24xx series of multi-purpose I2C expanders. (I think STMPE means ST Microelectronics Multi-Purpose Expander.) This PWM was designed in accordance with Nokia specifications and is kind of weird and usually just switched between max and zero duty cycle. However it is indeed a PWM so it needs to live in the PWM subsystem. This PWM is mostly used for white LED backlight.
