drm/bridge: dw-hdmi: Avoid including uapi headers

2025-04-16T22:54:06+00:00

It is not recommended for drivers to include UAPI header
directly.

drm/bridge: split HDMI Audio from DRM_BRIDGE_OP_HDMI

2025-04-07T12:48:23+00:00

As pointed out by Laurent, OP bits are supposed to describe operations.
Split DRM_BRIDGE_OP_HDMI_AUDIO from DRM_BRIDGE_OP_HDMI instead of
overloading DRM_BRIDGE_OP_HDMI.

drm/bridge: Add encoder parameter to drm_bridge_funcs.attach

2025-03-20T13:45:38+00:00

The drm_bridge structure contains an encoder pointer that is widely used
by bridge drivers. This pattern is largely documented as deprecated in
other KMS entities for atomic drivers.

However, one of the main use of that pointer is done in attach to just
call drm_bridge_attach on the next bridge to add it to the bridge list.
While this dereferences the bridge->encoder pointer, it's effectively
the same encoder the bridge was being attached to.

We can make it more explicit by adding the encoder the bridge is
attached to to the list of attach parameters. This also removes the need
to dereference bridge->encoder in most drivers.

drm/bridge: synopsys: Add audio support for dw-hdmi-qp

2025-02-27T10:43:21+00:00

Register the dw-hdmi-qp bridge driver as an HDMI audio codec.

The register values computation functions (for n) are based on the
downstream driver, as well as the register writing functions.

The driver uses the generic HDMI Codec framework in order to implement
the HDMI audio support.

drm/bridge: Pass full state to atomic_post_disable

2025-02-19T15:59:13+00:00

It's pretty inconvenient to access the full atomic state from
drm_bridges, so let's change the atomic_post_disable hook prototype to
pass it directly.

drm/bridge: dw-hdmi: Sync comment block with actual bus formats order

Commit d3d6b1bf85ae ("drm: bridge: dw_hdmi: fix preference of RGB modes
over YUV420") changed the order of the output bus formats, but missed to
update accordingly the "Possible output formats" comment section above
dw_hdmi_bridge_atomic_get_output_bus_fmts().

Fix the misleading comment block and a context related typo.
