Stefan Wahren	fd13c14426	pwm: bcm2835: Prevent division by zero ... It's possible that the PWM clock becomes an orphan. So better check the result of clk_get_rate() in order to prevent a division by zero.

Stefan Wahren	ebe88b6ae4	pwm: bcm2835: Calculate scaler in ->config() ... Currently pwm-bcm2835 assumes a fixed clock rate and stores the resulting scaler in the driver structure. But with the upcoming PWM clock support for clk-bcm2835 the rate could change, so calculate the scaler in the ->config() callback.
