ARM: dts: rockchip: Support UHS mode for SD card on PopMetal-RK3288 board
PopMetal-RK3288 board could enable SD3.0 card but need vccio_sd to support the voltage range from 1V8 to 3V3 and we also need to add more UHS mode here. Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
