[PATCH v2 0/3] Add PWM clock support for bcm2835

[Remi Pommarel]

Hi,

This patchset adds 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 two first patches fix the clock parent selection, while the second one is
actually adding the pwm clock registration.

Changes since v1:
	- determine_rate now based its parent selection upon divided rate
	  instead of the parent one
	- bcm2835_clock_choose_div has been modified to produce an avarage rate
	  lower or equal to the requested one
	- devicetree modifications have removed to be send in another patch

Remi Pommarel (3):
  clk: bcm2835: Always round up clock divisor
  clk: bcm2835: Support for clock parent selection
  clk: bcm2835: Add PWM clock support
