[U-Boot] [PATCH v2 0/5] add pinctrl driver for rk3399
This patch set add the pinctrl driver for rk3399 and enable pinctrl for pwm module. Module with pinctrl driver support and with interrupt number and default pinctrl in dts node will get pinctrl initialized when driver probe. Module like pwm which without interrupt number need to call the pinctrl API manually.
Changes in v2: - move and reg value MACRO in C source, and use MASK/SHIFT
