4cef29b64e drm/msm/mdp5: drop vdd regulator
The "vdd" regulator was used by the mdp5 driver only on downstream
kernels, where the GDSC is represented as a regulator. On all current
kernels the MDSS_GDSC is implemented as the power domain, removing the
need for this regulator. Remove it from the mdp5 driver.

ef7837ff09 drm/msm/dp: Add DP controllers for sc7280
The eDP controller on SC7280 is similar to the eDP/DP controllers
supported by the current driver implementation.

SC7280 supports one EDP and one DP controller which can operate
concurrently.

This change adds the support for eDP and DP controller on sc7280.

bb3de286d9 drm/msm/dp: Support up to 3 DP controllers
Based on the removal of the g_dp_display and the movement of the
priv->dp lookup into the DP code it's now possible to have multiple
DP instances.

In line with the other controllers in the MSM driver, introduce a
per-compatible list of base addresses which is used to resolve the
"instance id" for the given DP controller. This instance id is used as
index in the priv->dp[] array.

Then extend the initialization code to initialize struct drm_encoder for
each of the registered priv->dp[] and update the logic for associating
each struct msm_dp with the struct dpu_encoder_virt.

A new enum is introduced to document the connection between the
instances referenced in the dpu_intf_cfg array and the controllers in
the DP driver and sc7180 is updated.

Lastly, bump the number of struct msm_dp instances carries by priv->dp
to 3, the currently known maximum number of controllers found in a
Qualcomm SoC.

167dac97eb drm/msm/dp: Modify prototype of encoder based API
Functions in the DisplayPort code that relates to individual instances
(encoders) are passed both the struct msm_dp and the struct drm_encoder.
But in a situation where multiple DP instances would exist this means
that the caller need to resolve which struct msm_dp relates to the
struct drm_encoder at hand.

Store a reference to the struct msm_dp associated with each
dpu_encoder_virt to allow the particular instance to be associate with
the encoder in the following patch.

9960f7a899 drm/msm/dpu: Remove some nonsense
These aren't used.  And if we add use for them later, we should probably
do something a bit more structured than string parsing.

885455d6bf drm/msm: Change dpu_crtc_get_vblank_counter to use vsync count.
[why]
vsync_cnt atomic counter increments for every hw vsync. On the other
hand, frame count is a register that increments when the frame gets
actually pushed out. We cannnot read this register whenever the timing
engine is off, but vblank counter should still return a valid number.
This behavior also matches the downstream driver.

[How]
Read the encoder vsync count instead of the dpu_encoder_phys frame
count.

6087623e7c drm/msm/dpu: don't clear IRQ register twice
We already clear the IRQ status register before processing IRQs, so do
not clear the register again. Especially do not clear the IRQ status
_after_ processing the IRQ as this way we can loose the event.

a73033619e drm/msm/dpu: squash dpu_core_irq into dpu_hw_interrupts
With dpu_core_irq being the wrapper around dpu_hw_interrupts, there is
little sense in having them separate. Squash them together to remove
another layer of abstraction (hw_intr ops).

Both PINGPONG4 and PINGPONG5 IRQ registers are using the

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

5bccb945f3 drm/msm/disp/dpu1: add safe lut config in dpu driver
Add safe lut configuration for all the targets in dpu
driver as per QOS recommendation.

Issue reported on SC7280:

With wait-for-safe feature in smmu enabled, RT client
buffer levels are checked to be safe before smmu invalidation.
Since display was always set to unsafe it was delaying the
invalidaiton process thus impacting the performance on NRT clients
such as eMMC and NVMe.

Validated this change on SC7280, With this change eMMC performance
has improved significantly.

Changes in v2:
- Add fixes tag (Sai)
- CC stable kernel (Dimtry)

Changes in v3:
- Correct fixes tag with appropriate hash (stephen)
- Resend patch adding reviewed by tag
- Resend patch adding correct format for pushing into stable tree (Greg)
