Subject[RESEND PATCH] pwm: pwm-atmel-tcb: pinctrl support
Date
Hello,

I sent a patch 1 month ago to add pinctrl support to pwm-atmel-tcb
driver and didn't get any review.

Could you take a look?

This patch adds pins request for the pwm device exposed by the TC
block using the pinctrl subsystem.


Best Regards,

Boris
