[PATCH 00/11] Generalized broadcom cygnus gpio driver

Generalized pinctrl-cygnus-gpio driver so that it could be used for all
iProc architecture based future SoCs having same gpio pin controller.
Generalization process made the below changes in driver-

1. Removed pin mapping from driver and addressed this via DT through
"gpio-ranges" property.
2. Addressed number of pins from DT through "ngpios" property and removed
from driver.
3. Since all iProc based SoCs would use this driver hence renamed all
variables/macros/functions and even file name on iproc.

This patchset applies on v4.3-rc4 and is tested on cygnus SVK and could be
find at-

Pramod Kumar (11):
  dt-bindings: pinctrl: Optional DT property to support pin mappings
  pinctrl: Remove GPIO to Pinctrl pin mapping from driver
  dts: pinctrl: Add GPIO to Pinctrl pin mapping in DT
  dt-binding: Add new compatible string for gpio controller driver
  dt-binding: Add ngpios property to GPIO controller node
  dts: define ngpios property in gpio controller's node
  pinctrl: use ngpios propety from DT
  pinctrl: Add new compatible string to GPIO controller driver
  gpio: Rename func/macro/var to IP-block,iproc
  Documentation: Rename gpio controller name from cygnus to iproc
  pinctrl: Rename gpio driver from cygnus to iproc
