From 83173662bdbb012c9afe02571bbedfa67354dd66 Mon Sep 17 00:00:00 2001 From: Wadim Egorov Date: Tue, 13 Feb 2018 10:44:34 +0100 Subject: ARM: dts: rockchip: Support UHS mode for SD card on phyCORE-RK3288 RDK The phyCORE-RK3288 RDK could enable SD3.0 card but need vdd_io_sd to support the voltage range from 1.8V to 3.3V. And we have also to add relevant UHS modes to the sdmmc node. Let's also turn off the vdd_io_sd regulator in suspend state.
