This series provides a number of new features and improvements leading to enabling the keyboard (via Chrome OS EC) on jerry. This is conneected via SPI and uses its own message protocol.
Features and fixes are needed in the rockchip code to make this work include: - RK808 PMIC and regulator driver - Fixes and improvements to the i2c and SPI drivers - A full implementation of the GPIO driver - Additional clock support - Additional pinctrl support
The series moves a few rockchip boards to use the full pinctrl driver. I'm not sure this is a great idea, as it slows down start-up noticeably. It is currently needed for the display series (to come), but I intend to change that.
