    SubjectRe: [PATCH v2 1/1] arm64: dts: rockchip: Add support for TB-96AI board
    From
    Date
    Hi Mani,

    Thanks for your review. Please see comments inline.

    Yes. The USB ports can not work. I have already added all USB related
    setting. I tried

    rockchip internel rk3399.dtsi and the USB ports can work, so I think the
    cause is SoC related

    setting difference in mainline kernel.

    I can not figure it out for now, should I remove the usb related node in
    this patch?

    I am not very sure what the format exactly is. Is the LEDs format below
    right?

     49         leds {

    These pinctrl configs are used for sleep/wake. Since mainline MFD and
    pinctrl driver

    has no pinctrl support for RK809, these pinctrl configs will be removed
    other than default.

    No compatible needed. It is RK809 internel implement.

    Yes. This node will be removed.
