[PATCH 1/8] arm64: dts: rockchip: fix eeprom for Radxa ROCK 5A

[FUKAUMI Naoki]

Hi,

please ignore this patchset for Radxa ROCK 5A.

ROCK 5C is slightly updated version of ROCK 5A, and they are 99% 
identical from the perspective of device tree.

(if you want, you can use rk3588s-rock-5c.dts(dtb) for ROCK 5A)

I'll update ROCK 5C patchset to make commin .dtsi, then convert both 
ROCK 5A and 5C dts to use common (and up-to-date) .dtsi.

Best regards,
