Ok i will add it as KEY_VENDOR button.

I think it should be fixed regulator. It's used as vcc13-supply and vcc14-supply regulator on PMIC and it's same as other rk3588 boards.

Ok i will make this one "vbus_typec"

I agree with you but VCC3V3_PCIE30 is really confusing regulator name. I guess Xunlong made a mistake about it. I think we can name it as "vcc3v3_pcie20"
