| Series | [1/8] arm64: dts: rockchip: fix eeprom for Radxa ROCK 5A | expand |
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, -- FUKAUMI Naoki Radxa Computer (Shenzhen) Co., Ltd.
