Starting kernel but some failed messages

[Samhuang0727]

Hello everyone, I am currently trying to flash the Radxa kernel (branch stable-4.4-rockpi4) on the Rock Pi 4. However, during boot, I encounter numerous failure messages, including many "failed to get regulator" and "power control initialization failed" errors. I am unsure if this is due to incorrect configurations in the device tree configuration such as rk3399.dtsi and rk3399-rock-pi-4.dtsi files.

If anyone has encountered similar problems or has any suggestions, I would be very grateful 👍
