This patch series depends on and must be applied after:
https://lore.kernel.org/all/20260402-drm-lcdif-dbanc-v3-7-27cd247a0847@bootlin.com/
(Series [v3,00/11] drm/mxsfb/lcdif: use DRM_BRIDGE_ATTACH_NO_CONNECTOR and the bridge-connector)

Patch 1: Make DRM_BRIDGE_ATTACH_NO_CONNECTOR optional for platforms that call
         dw_hdmi_bind() to attach the dw-hdmi bridge.
Patch 2: Allow &dw_hdmi_plat_data.output_port = 0 without the attach flag
         DRM_BRIDGE_ATTACH_NO_CONNECTOR for dw-hdmi bridge.
Patch 3: Apply bridge-connector for Rockchip dw-hdmi driver, so that connector
         management is unified under bridge-connector. Treat dw-hdmi purely as
         a bridge without using its own connector helper functions, which
         partially overlaps with the bridge helper.
Patch 4: Add next bridge support for Rockchip dw-hdmi driver, so that it can
         support both the HDMI connector and additional bridge chips.

Damon Ding (4):
  drm/bridge: dw-hdmi: Pass bridge attach flags for dw_hdmi_bind()

    DRM_BRIDGE_ATTACH_NO_CONNECTOR
  drm/rockchip: dw_hdmi: Apply DRM_BRIDGE_ATTACH_NO_CONNECTOR and the
    bridge-connector
  drm/rockchip: dw_hdmi: Support to find the next bridge
