Revert "drm/bridge: Patch atomic hooks to take a drm_bridge_state"

2020-01-07T23:34:28+00:00

This reverts commit f7619a58ef92 ("drm/bridge: Patch atomic hooks to take a drm_bridge_state"). Commit 6ed7e9625fa6 ("drm/bridge: Add a drm_bridge_state object") introduced a circular dependency between drm.ko and drm_kms_helper.ko which uncovered a misdesign in how the whole thing was implemented. Let's revert all patches depending on the bridge_state infrastructure for now.

drm/bridge: Patch atomic hooks to take a drm_bridge_state

2020-01-07T09:10:59+00:00

This way the drm_bridge_funcs interface is consistent with the rest of the subsystem. The only driver implementing those hooks (analogix DP) is patched too.

drm: bridge: dw-hdmi: constify copied structure

2020-01-06T14:39:29+00:00

The dw_hdmi_hw structure is only copied into another structure, so make it const. The opportunity for this change was found using Coccinelle.

drm/bridge: lvds-codec: Simplify panel DT node localisation

2019-12-18T11:26:09+00:00

The probe function needs to get ahold of the panel device tree node, and it achieves that by using a combination of of_graph_get_port_by_id, of_get_child_by_name, and of_graph_get_remote_port_parent. We can achieve the same goal by replacing those calls with a call to of_graph_get_remote_node these days.

drm/bridge: lvds-codec: Add "lvds-decoder" support

2019-12-18T11:26:08+00:00

Add support for transparent LVDS decoders by adding a new compatible string ("lvds-decoder") to the driver. This patch also adds member connector_type to struct lvds_codec, and that's because LVDS decoders have a different connector type from LVDS encoders. We fill this new member up with the data matching the compatible string.

drm/bridge: Repurpose lvds-encoder.c

2019-12-18T11:26:07+00:00

lvds-encoder.c implementation is also suitable for LVDS decoders, not just LVDS encoders. Instead of creating a new driver for addressing support for transparent LVDS decoders, repurpose lvds-encoder.c for the greater good with this patch. This patch only "rebrands" the lvds-encoder.c driver, to make it suitable for hosting LVDS decoders support. The actual support for LVDS decoders will come with a later patch.
