Subject: Re: [PATCH 2/2] arm64: dts: rockchip: Add Radxa ROCK Pi E25
Hi,

there is no product called "ROCK Pi E25". it's "Radxa E25".

there is no product called "Radxa ROCK Pi CM3 IO (core board)". it's
"Radxa ROCK 3 Compute Module Industrial". (A.K.A. Radxa CM3I)
https://wiki.radxa.com/Rock3/CM/CM3I

SATA is working on my E25. you may refer my dts,

I think dts should be separated, CM3I dtsi and E25 dts.
