[PATCH 0/2] Add PWM clock support for bcm2835

Hi,

This patchset add support for pwm clock. At boot, this clock does not have a
default parent nor a default rate set. Thus we should be able to change its
parent to get this clock working. The current clock implementation is using a
mux to select the parent, but these clocks need to add a password (0x5a) in
higher register bits when changing parent. So a generic mux cannot be used
here.

The first patch fix the clock parent selection, while the second one is actually
adding the pwm clock registration.
