[PATCH 0/2] arm64: dts: renesas: Add SD/OE pin properties

Linux can configure almost every part of this clock generator without
relying on the OTP settings. However, the correct configuration for the
SD/OE pin cannot be determined automatically. Therefore, add the
appropriate properties to configure this pin.
I have CC'd some people who appear to have access to the following
boards which use the versaclock5:
- Salvator-X
- HiHope RZ/G2[MN] Main Board
- Beacon Embedded Works RZ/G2N Development Kit
as I could not find schematics for these boards. You can help me out by
(pick one):
- Run the following command and send me the output:
$ grep 10: /sys/kernel/debug/regmap/*-006a/registers
- Measure the voltage on the SD/OE pin on a functioning board.
- Inspect (or send me) the schematic to determine the state of the SD/OE
pin during normal operation.
My suspicion is that all of these boards use the same configuration
(SD/OE pin tied high) owing to their common design heritage. Thanks in
advance.
