From: Andy Yan <andy.yan@rock-chips.com> The HDMI0(Port next to Headphone Jack) is drived by DP1 on rk3588 via RA620(a dp2hdmi converter). Add related dt nodes to enable it. Note: ROCKCHIP_VOP2_EP_DP1 is defined as 11 in dt-binding header, but it will trigger a dtc warning like "graph node unit address error, expected "b"" if we use it directly after endpoint, so we use "b" instead here. Signed-off-by: Andy Yan <andy.yan@rock-chips.com> --- (no changes since v3) Changes in v3: - Add RA620 into bridge chain. .../boot/dts/rockchip/rk3588-rock-5-itx.dts | 59 +++++++++++++++++++ 1 file changed, 59 insertions(+)
