drm/bridge: analogix_dp: Attach the next bridge in analogix_dp_bridge_attach()

2026-04-13T15:43:45+00:00

Uniformly, move the next bridge attachment to the Analogix side
rather than scattered on Rockchip and Exynos sides. It can also
help get rid of the callback &analogix_dp_plat_data.attach() and
make codes more concise.

drm/bridge: analogix_dp: Add new API analogix_dp_finish_probe()

2026-04-13T15:42:30+00:00

Since the panel/bridge should logically be positioned behind the
Analogix bridge in the display pipeline, it makes sense to handle
the panel/bridge parsing on the Analogix side. Therefore, we add
a new API analogix_dp_finish_probe(), which combines the panel/bridge
parsing with component addition, to do it.

In order to process component binding right after the probe completes,
the &analogix_dp_plat_data.ops is newly added to pass &component_ops,
for which the &dp_aux_ep_device_with_data.done_probing() of DP AUX bus
only supports passing &drm_dp_aux.

drm/bridge: analogix_dp: Remove unused struct drm_connector* for &analogix_dp_plat_data.attach()

2026-04-09T12:10:46+00:00

For both Rockchip and Exynos sides, the struct drm_connector* is
never used in callback &analogix_dp_plat_data.attach(). After
applying drm_bridge_connector helper, this parameter will no longer
be used at all.

drm/bridge: Move legacy bridge driver out of imx directory for multi-platform use

2026-04-09T12:10:21+00:00

As suggested by Dmitry, the DRM legacy bridge driver can be pulled
out of imx/ subdir for multi-platform use. The driver is also renamed
to make it more generic and suitable for platforms other than i.MX.

drm/bridge: analogix_dp: Add &analogix_dp_plat_data.next_bridge

2026-04-09T12:10:08+00:00

In order to move the panel/bridge parsing and attachmenet to the
Analogix side, add component struct drm_bridge *next_bridge to
platform data struct analogix_dp_plat_data.

The movement makes sense because the panel/bridge should logically
be positioned behind the Analogix bridge in the display pipeline.

drm/display: hdmi: Use drm_output_color_format instead of hdmi_colorspace

2026-03-24T12:54:35+00:00

The hdmi_colorspace enum was defined to represent the colorspace value
of the HDMI infoframes. It was later used by some HDMI drivers to
express the output format they should be setting up.

During the introduction of the HDMI helpers, it then was used to
represent it in the drm_connector_hdmi_state structure.

However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_*
defines, and now with the drm_output_color_format enum. Let's
consolidate around drm_output_color_format in drm_connector_hdmi_state
to facilitate the current effort to provide a global output format
selection mechanism.
