The compatible should be "renesas,pwm-rcar", and one the the SoC
specific string. So, this patch revises the documentation.

The PWM controller on sun5i SoCs is identical to the one found on sun7i
SoCs. On the A13 package only one of the 2 pins is routed to the outside,
so only advertise one PWM channel there.

Document the device-tree binding of MediaTek display PWM. The PWM has
one channel to control the backlight brightness for display. Both the
MT8173 and MT6595 are supported.

Pull pwm changes from Thierry Reding:
 "Not much has been happening in PWM land lately, so this contains
  mostly minor fixes that didn't seem urgent enough for a late
  pull-request last cycle"

* tag 'pwm/for-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm:
  pwm: Remove __init initializer for pwm_add_table()
  pwm: samsung: Fix output race on disabling
  pwm: mxs: Fix period divider computation
  pwm: atmel-hlcdc: Add errata handling for sama5d4
  pwm: pca9685: Constify struct regmap_config
  pwm: imx-pwm: add explicit compatible strings and required clock properties

This patchset attempts to standardize the naming of dt-bindings
documents based on the Broadcom vendor prefix of brcm.

Although there are no guidelines currently present for how to name
the dt-bindings document the "vendor,binding.txt" style is in use by
some of the other vendors.

The imx-pwm binding contains language indicating compatible strings to
be used that is not valid for all supported parts e.g. Should be
"fsl,<soc>-pwm". Fix this by enumerating the valid compatible strings
that represent the two versions of this peripheral in use.

The binding is also missing the clocks/clock-names properties so
document these, the two required ipg and per clocks, and add these
properties to the example.
