Subject: [PATCH] arm64: dts: imx8mm-venice-*: add RTC aliases
|
|
|
|
Add aliases for the RTCs on the Gateworks Venice boards and on the imx8m
|
|
SoC. This ensures that the primary RTC is always the one on-board
|
|
provided by the Gateworks System Controller (GSC) which is battery
|
|
backed as opposed to the one in the IMX8M.
