[PATCH] arm64: dts: hikey: Enable HS200 mode on eMMC

2018-01-17 Thread oscardagrach
According to the hi6220 datasheet, the MMC controller is JEDEC eMMC 4.5 compliant, in addition to supporting a clock of up to 150MHz. The Hikey schematic also indicates the device utilizes 1.8v signaling. Define these parameters in the device tree to enable HS200 mode. Signed-off-by: Ryan Grachek
