2020-12-03	pwm: sl28cpld: fix getting driver data in pwm callbacks	Uwe Kleine-König	1	-2/+4
	Currently .get_state() and .apply() use dev_get_drvdata() on the struct device related to the pwm chip. This only works after .probe() called platform_set_drvdata() which in this driver happens only after pwmchip_add() and so comes possibly too late. Instead of setting the driver data earlier use the traditional container_of approach as this way the driver data is conceptually and computational nearer.

2020-09-17	pwm: Add support for sl28cpld PWM controller	Michael Walle	1	-0/+270
	Add support for the PWM controller of the sl28cpld board management controller. This is part of a multi-function device driver. The controller has one PWM channel and can just generate four distinct frequencies.
