pinctrl: rockchip: add rk3188 routes to switch between nand and emmc (ada62b7c) · Commits · 戴 / test

The rk3188 has pins that are not handled through the regular iomuxing for handling either nand-flash or an emmc and are set through only one specifal setting. So utilize the routing function to simply do that setting depending on one of the core nand/emmc signals that are actually regular pins handled through pinctrl. Signed-off-by:
