drm/bridge: analogix_dp: Add support for RK3576

2026-06-02T20:09:03+00:00

Add RK3576_EDP device type entry and extend Rockchip check to match existing hardware capabilities shared with RK3588. Set identical maximum link rate and lane count parameters for RK3576 eDP controller to reuse existing RK3588 config.

drm/bridge: analogix_dp: Rename and simplify is_rockchip()

2026-06-02T20:09:02+00:00

Rename inline helper is_rockchip() to analogix_dp_is_rockchip() to follow driver namespace convention consistently across code. Replace chained equality comparisons with switch-case layout to improve readability and simplify adding new SoC entries later.

drm/bridge: synopsys: dw-dp: Support unregistering the AUX channel

2026-06-02T19:27:59+00:00

The DisplayPort AUX channel gets initialized and registered during dw_dp_bind(), but it is never unregistered, which may lead to resource leaks and/or use-after-free. Add the missing dw_dp_unbind() function to allow the users of the library to handle the required cleanup, i.e. unregister the AUX adapter.

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.

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.
