Subject: [PATCH v9 0/2] PWM: pwm-atmel: add PWM controller driver

This patch series add Atmel PWM controller driver support.

Changes in v9:
  - Address the comments from Thierry Reding

Changes in v8:
  - replace pr_err by dev_err

Changes in v7:
  - fix issue for none device tree issues.

Changes in v6:
  - using relaxed version for writel and readl
  - add none device tree support
  - change some define from lower case to upper case
  - split device tree binding document as a separate patch

Changes in v5:
  - call clk_disable directly, if so, it won't cause more than one channel
    enabled, the clock can not be disabled.

Changes in v4:
  - check the return value of clk_prepare()
  - change channel register size as constant

Changes in v3:
  - change compatible string from "atmel,sama5-pwm" to "atmel,sama5d3-pwm"
  - Add PWM led example in binding documentation
  - Using micro replace hard code

Changes in v2:
  - Address the comments from Thierry Reding
