Subject: [PATCH v7 0/5] ARM: berlin: PWM support

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 v6:
        - Used a prescaler_table again
        - Removed the spinlock
        - Used inline function for read/write
        - Always disable the clock in _remvove()
        - Cosmtic updates
	- Reordered the Documentation patch

Changes since v5:
        - Rebased on top of 4.3-rc1
        - Added a call to clk_disable_unprepare() in case of failure

        - Reworked _remove()
        - Reworked _enable()

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[]
