[PATCH v1 1/1] ARM: dts: colibri: introduce dts with UHS-I support enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Introduce DTS for Colibri iMX6DL with proper configuration for VGEN3,
which allows that rail to be automatically switched to 1.8 volts for
proper UHS-I operation mode.
