[PATCH v6 0/3] Add gpio support to Broadcom Cygnus SoC

From: Ray Jui
Date: Mon Dec 15 2014 - 21:18:46 EST

This patchset contains the initial GPIO support for the Broadcom Cygnus SoC.
Cygnus has 3 GPIO controllers: 1) the ASIU GPIO; 2) the chipCommonG GPIO;
and 3) the ALWAYS-ON GPIO. All 3 types of GPIO controllers are supported by
the same Cygnus GPIO driver

Changes from v5:
- Get rid of DT property "linux,gpio-base". Use dynamic allocation for GPIO base

Changes from v4:
- Use DT property "linux,gpio-base" to define GPIO base number
- factorize common code to improve code readability and reduce code size
- remove "bcm_" prefix on function and struct names
- improve debugging prints
- default GPIO_BCM_CYGNUS to y in Kconfig (it still depends on
ARCH_BCM_CYGNUS). This way we do not need to select it from the
- Get rid of redundant MAINTAINER entry for this driver. It will be maintained
by Broadcom iProc/Cygnus maintainers
- Update device tree document based on driver changes

Changes from v3:
- Fix dt property tpyo
- Fix incorrect GPIO compatible ID in device tree binding document example

Changes from v2:
- Consolidate different compatible IDs into "brcm,cygnus-gpio"
- Get rid of redundant "no-interrupt" property

Changes from v1:
- Get rid of inline qualifier
- Get rid of redundant check in the ISR
- Other minor fixes to imrove code readability

gpio: Cygnus: add GPIO driver
ARM: dts: enable GPIO for Broadcom Cygnus
