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.
