drm/msm/mdp4: add LVDS panel support
LVDS panel support uses the LCDC (parallel) encoder. Unlike with HDMI,
there is not a separate LVDS block, so no need to split things into a
bridge+connector. Nor is there is anything re-used with mdp5.
Note that there can be some regulators shared between HDMI and LVDS (in
particular, on apq8064, ext_3v3p), so we should not use the _exclusive()
variants of devm_regulator_get().
The drm_panel framework is used for panel-specific driver.

drm/msm/mdp4: fix blend setup with multiple crtcs
In particular, blend_setup() should not overwrite the other crtc's mixer
settings. Also, the encoder needs to be able to specify the mixer-id
explicitly, since both LVDS and DTV use 'INTF_LVDC_DTV', so we cannot
guess the mixer-id from the interface.

drm/msm: use upstream iommu
Downstream kernel IOMMU had a non-standard way of dealing with multiple
devices and multiple ports/contexts. We don't need that on upstream
kernel, so rip out the crazy.
Note that we have to move the pinning of the ringbuffer to after the
IOMMU is attached. No idea how that managed to work properly on the
downstream kernel.
For now, I am leaving the IOMMU port name stuff in place, to simplify
things for folks trying to backport latest drm/msm to device kernels.
Once we no longer have to care about pre-DT kernels, we can drop this
and instead backport upstream IOMMU driver.

drm/msm/mdp4: add mdp axi clk
Downstream kernel holds this clk via a fake-parent relationship.
Upstream clock framework requires that we hold it explicitly.

drm/msm: DT support for 8960/8064 (v3)
Now that we (almost) have enough dependencies in place (MMCC, RPM, etc),
add necessary DT support so that we can use drm/msm on upstream kernel.
v2: update for review comments
v3: rebase on component helper changes

drm/msm/mdp4: cure for the cursor blues (v2)
The hw cursor is relatively adept at triggering underflows, which
manifest as a "blue flash" (since blue is configured as the underflow
color). Juggle a few things around to tighten up the timing for setting
cursor registers in DONE irq.
And most importantly, don't ever disable the hw cursor. Instead flip it
to a blank/empty cursor. This seems far more reliable, as even simply
clearing the cursor-enable bit (with no other updates in previous/
following frames) can in some cases cause underflow.
v1: original
v2: add missing locking spotted by Micah

drm/msm: add hdmi support for apq8x74/mdp5
The HDMI block is basically the same between older SoC's with mdp4
display controller, and newer ones with mdp5.
So mostly this consists of better abstracting out the different sets of
regulators, clks, etc. In particular, for regulators and clks we can
split it up by what is needed for hot plug detect to work, and what is
needed to light up the display.
Also, 8x74 has a new phy.. a very simple one, but split out into a
different mmio space. And with mdp5, the irq is shared with mdp, so we
don't directly register our own irq handler.

There are some little bits and pieces that mdp4 and mdp5 can share, so
move things around so that we can have both in a common parent
directory.
