[PATCH 0/3] pwm support for Broadcom iProc SoC's

[Yendapally Reddy Dhananjaya Reddy]

This patchset contains the pwm support for the Broadcom's iProc SoC's.

The first patch provides the documentation details and the
second patch contains the controller support details. The third patch
contains the enable method for Northstar Plus SoC.

This patchset has been tested on NSP bcm958625HR board.
This patchset is based on v4.5.0-rc1 and is available from github
repo: https://github.com/Broadcom/cygnus-linux.git
branch: iproc-pwm-v1
