Subject: [PATCH 00/10] Add Actions Semi S900 pinctrl and gpio support

This patchset adds pinctrl and gpio support for Actions Semi S900 SoC.
Pinctrl and gpio subsystems share the common set of register range but
implemented as individual drivers for making it less complex.

Pinmux functions are only accessible for pin groups while pinconf
parameters are available for both pin groups and individual pins.

gpio-line-names has been added for the Bubblegum-96 board matching the
96Boards CE specification v1.0.

Both pinctrl and gpio drivers are verified using the Bubblegum-96 board.

This patchset depends on the clock driver which is still under review:
