arm64: dts: rockchip: vdd_log on rk3399-sapphire is not an i2c slave
The vdd_log power supply is controlled by a PWM pin, not by i2c register access. There is a boot message that reports an error about not being able to bring that supply up. Signed-off-by: Vicente Bergas <vicencb@gmail.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de>
