<title>drm/connector: hdmi: Fix writing Dynamic Range Mastering infoframes</title>

<id>urn:sha1:f0fa69b5011a45394554fb8061d74fee4d7cd72c</id>
<content type='text'>
The largest infoframe we create is the DRM (Dynamic Range Mastering)
infoframe which is 26 bytes + a 4 byte header, for a total of 30
bytes.

With HDMI_MAX_INFOFRAME_SIZE set to 29 bytes, as it is now, we
allocate too little space to pack a DRM infoframe in
write_device_infoframe(), leading to an ENOSPC return from
hdmi_infoframe_pack(), and never calling the connector's
write_infoframe() vfunc.

Instead of having HDMI_MAX_INFOFRAME_SIZE defined in two places,
replace HDMI_MAX_INFOFRAME_SIZE with HDMI_INFOFRAME_SIZE(MAX) and make
MAX 27 bytes - which is defined by the HDMI specification to be the
largest infoframe payload.

Fixes: c602e4959a0c ("drm/connector: hdmi: Create Infoframe DebugFS entries")

<title>drm/dp_mst: Fix DSC decompression detection in Synaptics branch devices</title>

<id>urn:sha1:70a6587dca37a3cf12ab323f7fd73266abfc274f</id>
<content type='text'>
Atm it's assumed that all Synaptics MST branch devices support DSC,
which is not exposed via a DP-to-DP peer device, rather a control flag
in the branch device's UFP DPCD applying to all the streams going
through it. This isn't true for all adapters with this branch device
though (for instance the Cakitte USBC-&gt;2xHDMI adapter reported in the
Closes link below doesn't support DSC).

Fix the above by advertising the DSC decompression support only if the
capability flag for this in the UFP DPCD is actually set.

<id>urn:sha1:9a71cf8b6fa433a8f243626ba9930a3870584e38</id>
<content type='text'>
On HDMI connectors which use drm_bridge_connector and DRM_BRIDGE_OP_HDMI
IGT chokes on the max_bpc property in several kms_properties tests due
to the drm_bridge_connector failing to reset HDMI-related
properties.

Call __drm_atomic_helper_connector_hdmi_reset() if the
drm_bridge_connector has bridge_hdmi.

It is impossible to call this function from HDMI bridges, none of the
bridge callbacks correspond to the drm_connector_funcs::reset().

drm_bridge_connector is a "leaf" driver, belonging to the display
helper, rather than the "CRTC" drm_kms_helper module. Move the driver
to the drm/display and add necessary Kconfig selection clauses.

<title>drm/display: stop depending on DRM_DISPLAY_HELPER</title>

<content type='text'>
Kconfig symbols should not declare dependency on DRM_DISPLAY_HELPER.
Move all parts of DRM_DISPLAY_HELPER to an if DRM_DISPLAY_HELPER block.

It is not possible to make those symbols select DRM_DISPLAY_HELPER
because of the link issues when a part of the helper is selected to be
built-in, while other part is selected to be as module. In such a case
the modular part doesn't get built at all, leading to undefined symbols.

The only viable alternative is to split drm_display_helper.ko into
several small modules, each of them having their own dependencies.

Instead of just smashing jiffies into a GUID, use guid_gen() to generate
RFC 4122 compliant GUIDs.
