The bindings for Qualcomm opp levels changed after being Acked but before landing. Thus the code in the GPU driver that was relying on the old bindings is now broken. Let's change the code to match the new bindings by adjusting the old string 'qcom,level' to the new string 'opp-level'. See the patch ("dt-bindings: opp: Introduce opp-level bindings"). NOTE: we will do additional cleanup to totally remove the string from the code and use the new dev_pm_opp_get_level() but we'll do it in a future patch. This will facilitate getting the important code fix in sooner without having to deal with cross-maintainer dependencies. This patch needs to land before the patch ("arm64: dts: sdm845: Add gpu and gmu device nodes") since if a tree contains the device tree patch but not this one you'll get a crash at bootup.

Do some debugfs cleanups from across the DPU driver. The DRM destroy functions will do a recursive delete on the entire debugfs node so there is no need to store dentry pointers for the debugfs files that are persistent for the life of the driver. This also means that the destroy functions can go away too. Also, use standard API functions where applicable instead of using hand written code. v3: No changes v2: Add more code; most of the dpu debugfs files should be addressed now. Reviewed-by:

Instead of assigning/clearing the crtc on vblank enable/disable, we can just assign and clear the crtc on modeset. That allows us to just toggle the encoder's vblank interrupts on vblank_enable. So why is this important? Previously the driver was using the legacy pointers to assign/clear the crtc. Legacy pointers are cleared _after_ disabling the hardware, so the legacy pointer was valid during vblank_disable, but that's not something we should rely on. Instead of relying on the core ordering the legacy pointer assignments just so, we'll assign the crtc in dpu_crtc enable/disable. This is the only place that mapping can change, so we're covered there. We're also taking advantage of drm_crtc_vblank_on/off. By using this, we ensure that vblank_enable/disable can never be called while the crtc is off (which means the assigned crtc will always be valid). As such, we don't need to use modeset locks or the crtc_lock in the vblank_enable/disable routine to be sure state is consistent. ...I think.

The indirection of registering a callback and opaque pointer isn't reall useful when there's only one callsite. So instead of having the vblank_cb registration, just give encoder a crtc and let it directly call the vblank handler. In a later patch, we'll make use of this further.

I think the intention here was to protect the enc->crtc access, but that's insufficient to avoid enc->crtc changing. Fortunately we're already holding the modeset lock when this is called (from atomic_check), so remove the crtc_lock and add a modeset lock check. While we're at it, use the encoder mask from crtc state instead of legacy pointer. Changes in v2: - None Reviewed-by:

There are 4 times that _dpu_crtc_vblank_enable_no_lock() is called: 1- crtc enable 2- crtc disable 3- crtc vblank enable 4- crtc vblank disable When we enable or disable the crtc, we call drm_crtc_vblank_on and drm_crtc_vblank_off respectively. That will gate vblank enables and disables to only being called when the crtc is active. That means that we can just enable/disable pm runtime in crtc enable/disable. This will be beneficial in trying to eliminate blocking calls from the vblank call chain. Changes in v2: - None Reviewed-by:

The crtc runtime resume doesn't actually operate on the crtc, but rather its encoders. The problem with this is that we need to inspect the crtc state to get the currently connected encoders. Since runtime resume isn't guaranteed to be called while holding the modeset locks (although it sometimes is), this presents a race condition. Now that we have ->enabled on the virtual encoders, and a lock to protect it, just call resume on each encoder and only restore the ones that are enabled.
