    Subject[PATCH v4 3/5] ARM: dts: sun8i: Add Reduced Serial Bus controller device node to A23/A33 dtsi
    Date
    This patch adds a device node for the Reduced Serial Bus (RSB)
    controller and the defacto pinmux setting to the A23/A33 dtsi.

    Since there is only one possible pinmux setting for RSB, just
    set it in the dtsi.

    Signed-off-by: Chen-Yu Tsai <wens@csie.org>

    Changes since v3:

    - Changed #address-cells to 1
