[PATCHv4 6/7] arm64: dts: rockchip: Add rock-5a board
Posted by Sebastian Reichel 2 months, 1 week ago
Add board file for the RK3588s Rock 5A board. While the hardware
offers plenty of peripherals and connectivity this basic implementation
just handles things required to access eMMC, UART and Ethernet (i.e.
enough to successfully boot Linux).

Isn't your Signed-off-by: tag supposed to come first? (This question
also holds for patches 1, 2 (your S-o-B before the Reviewed-by) and 4 of
this series.

Documentation says that the MAC should not add an RX delay in the
"rgmii-rxid" case, but it is specified. Is this really necessary?

No pinctrl required for this reset pin?
