[PATCH 0/5] pwm: atmel-tcb: Some driver maintenance

[Uwe Kleine-König]

Hello,

here come some improvements to the pwm-atmel-tcb driver.

There are still a few opportunities to improve the driver. For example
.duty shouldn't be relevant for atmel_tcb_pwm_disable(). Also the driver
could be converted from of_clk_get_by_name to devm_clk_get() (and then
also devm_pwmchip_add()). Further more I think all members of
atmel_tcb_pwm_device could be dropped as they are all only used in
.apply() after they were assigned earlier in the same function; similar
to how I removed the polarity member. Maybe someone with the hardware
wants to chime in?

Best regards
Uwe
