[PATCH v4 0/5] ARM: berlin: PWM support

[Antoine Tenart]

Hi all,

This series adds a driver for the Marvell Berlin PWM controller, which
has 4 channels.

This has been tested on a BG2Q DMP.

Thanks,

Antoine

Changes since v3:
	- Use readl_relaxed
	- Reworked the clk enable / clk disable calls
	- Removed BERLIN_PWM_DISABLE

Changes since v2:
        - Reworked the prescaler/tcnt calculation
        - Added an input clock
        - Updated the documentation
        - Reordered the pwm node
        - Added some definition for BIT()

Changes since v1:
        - Added a sentinel in berlin_pwm_match[]
