2021-09-02pwm: ntxec: Simplify using devm_pwmchip_add()Uwe Kleine-König1-12/+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 <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2021-09-02pwm: ntxec: Drop useless assignment to struct pwmchip::baseUwe Kleine-König1-1/+0
Since commit f9a8ee8c8bcd ("pwm: Always allocate PWM chip base ID dynamically") there is no effect any more for assigning this variable. When the patch resulting in f9a8ee8c8bcd was created, this driver didn't exist yet, so this was missed.

2021-03-10pwm: ntxec: Add driver for PWM function in Netronix ECJonathan Neuschäfer1-0/+184
The Netronix EC provides a PWM output which is used for the backlight on some ebook readers. This patches adds a driver for the PWM output. The .get_state callback is not implemented, because the PWM state can't be read back from the hardware.
