Subject: ARM: rockchip: Remove the pinctrl request at rk3288-board-spl
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=08c817c39908f9d120df1e4c90ddad4a11fc3891;p=u-boot.git

ARM: rockchip: Remove the pinctrl request at rk3288-board-spl

If we use the new pinctrl driver, the pinctrl setup will be done
by device probe. Remove the pinctrl setup at rk3288-board-spl.
