399af57ccc dt-bindings: display/msm/gpu: fix the schema being not applied 
dtschema v2024.4, v2024.5 and maybe earlier do not select device nodes for
given binding validation if the schema contains compatible list with
pattern and a const fallback.  This leads to binding being a no-op - not
being applied at all.  Issue should be fixed in the dtschema but for now
add a work-around do the binding can be used against DTS validation.

d6c7c411be dt-bindings: display/msm/gpu: constrain clocks in top-level 
We expect each schema with variable number of clocks, to have the widest
constrains in top-level "properties:".  This is more readable and also
makes binding stricter, if there is no "if:then:" block for given

5b90752f96 drm/msm/dpu: remove CRTC frame event callback registration 
The frame event callback is always set to dpu_crtc_frame_event_cb() (or

14b27d5df3 drm/msm/a7xx: Initialize a750 "software fuse" 
On all Qualcomm platforms with a7xx GPUs, qcom_scm provides a method to
initialize cx_mem. Copy this from downstream (minus BCL which we
currently don't support). On a750, this includes a new "fuse" register
which can be used by qcom_scm to fuse off certain features like
raytracing in software. The fuse is default off, and is initialized by
calling the method. Afterwards we have to read it to find out which
features were enabled.

6b4468b0c6 drm/bridge-connector: implement glue code for HDMI connector 
In order to let bridge chains implement HDMI connector infrastructure,
add necessary glue code to the drm_bridge_connector. In case there is a
bridge that sets DRM_BRIDGE_OP_HDMI, drm_bridge_connector will register
itself as a HDMI connector and provide proxy drm_connector_hdmi_funcs
implementation.

Note, to simplify implementation, there can be only one bridge in a
chain that sets DRM_BRIDGE_OP_HDMI. Setting more than one is considered
an error. This limitation can be lifted later, if the need arises.
