Commit Message

Tim Harvey Sept. 9, 2024, 10:15 p.m. UTC 
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.
