Memory barriers help ensure instruction ordering, NOT time and order of actual write arrival at other observers (e.g. memory-mapped IP). On architectures employing weak memory ordering, the latter can be a giant pain point, and it has been as part of this driver. Moreover, the gpu_/gmu_ accessors already use non-relaxed versions of readl/writel, which include r/w (respectively) barriers. Replace the barriers with a readback (or drop altogether where possible) that ensures the previous writes have exited the write buffer (as the CPU must flush the write to the register it's trying to read back).

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. Signed-off-by:

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 variant. Acked-by:

The frame event callback is always set to dpu_crtc_frame_event_cb() (or to NULL) and the data is always either the CRTC itself or NULL (correpondingly). Thus drop the event callback registration, call the dpu_crtc_frame_event_cb() directly and gate on the dpu_enc->crtc assigned using dpu_encoder_assign_crtc(). Signed-off-by:

Command mode panels provide TE signal back to the DSI host to signal that the frame display has completed and update of the image will not cause tearing. Usually it is connected to the first GPIO with the mdp_vsync function, which is the default. In such case the property can be skipped. Acked-by:

clear_pending_flush() ctl op is always assigned irrespective of the DPU hardware revision. Hence there is no needed to check whether the op has been assigned before calling it. Drop the checks across the driver for clear_pending_flush() and also update its documentation that it is always expected to be assigned. changes in v2: - instead of adding more validity checks just drop the one for clear_pending_flush - update the documentation for clear_pending_flush() ctl op - update the commit text reflecting these changes changes in v3: - simplify the documentation of clear_pending_flush Fixes: d7d0e73f ("drm/msm/dpu: introduce the dpu_encoder_phys_* for writeback") Reported-by:

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. Reviewed-by:
