Hi Linus,
This patchset mainly focuses on providing support to configure SPEAr pads as
gpios. For this i have added a gpiolib based driver and few changes in other
SPEAr pinctrl drivers.
It also contains minor fixes.
V1->V2:
- Passing gpio node via DT. Patch for this support in gpiolib is
gpiolib: Add of_get_gpio_chip_by_phandle() helper
- Other minor fixes
Viresh Kumar (5):
pinctrl: SPEAr: Don't set all non muxreg bits on pinctrl_disable
pinctrl: SPEAr1310: Fix pin numbers for clcd_high_res
pinctrl: SPEAr: Add plgpio driver
pinctrl: SPEAr: Add gpio ranges support
SPEAr: Add plgpio node in device tree dtsi files

Most of SPEAr SoCs, which support pinctrl, can configure & use pads as gpio.
This patch adds plgpio driver for configuring these pads as gpio.

To: linux-arm-kernel
Most of SPEAr SoCs, which support pinctrl, can configure & use pads as gpio.
This patch gpio enable support for SPEAr pinctrl drivers.
