Subject: [PATCH v3 3/3] arm64: dts: exynosautov920: add ufs phy for
ExynosAutov920 SoC
Add UFS Phy for ExynosAutov920
Like ExynosAutov9, this also uses fixed-rate clock nodes until clock driver
has been supported. The clock nodes are initialized on bootloader stage
thus we don't need to control them so far.
