https://gitlab.freedesktop.org/drm/msm into drm-next
+ usual progress on cleanups
+ dsi vs EPROBE_DEFER fixes
+ msm8998 (snapdragon 835 support)
+ a540 gpu support (mesa support already landed)
+ dsi, dsi-phy support
+ mdp5 and dpu interconnect (bus/memory scaling) support
+ initial prep work for per-context pagetables (at least the parts that
don't have external dependencies like iommu/arm-smmu)
There is one more patch for fixing DSI cmd mode panels (part of a set of
patches to get things working on nexus5), but it would be conflicty with
1cff7440a86e04a613665803b42034 in drm-next without rebasing or back-merge,
and since it doesn't conflict with anything in msm-next, I think it best
if Sean merges that through drm-mix-fixes instead.
(In other news, I've been making some progress w/ getting efifb working
properly on sdm850 laptop without horrible hacks, and drm/msm + clk stuff
not totally falling over when bootloader enables display and things are
already running when driver probes.. but not quite ready yet, hopefully
we can post some of that for 5.4.. should help for both the sdm835 and
sdm850 laptops.)

The DSI controller on the MSM8998 SoC is a 6G v2.0.0 controller which is
very similar to the v2.0.1 of SDM845.

For dual dsi mode, the horizontal timing needs
to be divided by half since both the dsi controllers
will be driving this panel. Adjust the pixel clock and
DSI timing accordingly.
Changes in v3:
- Added Archit's R-b
- Rebase on dsi cleanup set in msm-next

Add 8x96 DSI data in dsi_cfg. The downstream kernel's dsi_host driver
enables core_mmss_clk. We're seeing some branch clock warnings on
8x96 when enabling this. There doesn't seem to be any negative effect
with not enabling this clock, so use it once we figure out why we
get the warnings.

The DSI host and PHY driver currently expects the DT bindings to provide
custom properties "qcom,dsi-host-index" and "qcom,dsi-phy-index" so that
the driver can identify which DSI instance it is.
The binding isn't acceptable, but the driver still needs to figure out
what its instance id. This is now done by storing the mmio starting
addresses for each DSI instance in every SoC version in the driver. The
driver then identifies the index number by trying to match the stored
address with comparing the resource start address we get from DT.
We don't have compatible strings for DSI PHY on each SoC, but only the
DSI PHY type. We only support one SoC version for each PHY type, so we
get away doing the same thing above for the PHY driver. We can revisit
this when we support two SoCs with the same DSI PHY.

Add a dsi_cfg entry for APQ8064. Since this is the first DSIv2 chip to
be supported, add a list of bus clocks that are required by the DSIv2
block.

DSI bus clocks seem to vary between different DSI host versions, and the
SOC to which they belong. Even the enable/disable sequence varies.
Provide a list of bus clock names in dsi_cfg. The driver will use this to
retrieve the clocks, and enable/disable them.
Add bus clock lists for DSI6G, and DSI for MSM8916(this is DSI6G too, but
there is no MMSS_CC specific clock since there is no MMSS clock controller
on 8916).

With more platforms supported, the DSI host
configuration array keeps expanding. This change
moves those to a separate dsi_cfg module.
