[PATCH v2 6/9] arm64: dts: renesas: white-hawk-cpu: Factor out common parts
Geert Uytterhoeven
geert+renesas at glider.be
Thu Jan 25 06:48:56 PST 2024
Factor out the parts on the White Hawk CPU board that are also present
on the White Hawk Single board, so they can be reused when introducing
support for the latter.
Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

v2:
- Rebase on top of commit fc67495680f60e88 ("arm64: dts: renesas:
white-hawk-cpu: Fix missing serial console pin control",
- Split off restoring sort order into its own patch.
