Stephane Viau b77f47e789 drm/msm/hdmi: set hdp clock rate before prepare_enable
The clock driver usually complains when a clock is being prepared
before setting its rate. It is the case here for "core_clk" which
needs to be set at 19.2 MHz before we attempt a prepare_enable().

Rob Clark 3189650d7f drm/msm/hdmi: use gpio and HPD polling
The hotplug detect and irq does not seem to be reliable on all devices
for some reason.  For now it is more reliable to use polling, and give
preference to raw gpio status if it disagrees with the debounced hpd
status.

Rob Clark dada25bd22 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.

Rob Clark a3376e3ec8 drm/msm: convert to drm_bridge
Drop the msm_connector base class, and special calls to base class
methods from the encoder, and use instead drm_bridge.  This allows for a
cleaner division between the hdmi (and in future dsi) blocks, from the
mdp block.

Rob Clark c8afe684c9 drm/msm: basic KMS driver for snapdragon
The snapdragon chips have multiple different display controllers,
depending on which chip variant/version.  (As far as I can tell, current
devices have either MDP3 or MDP4, and upcoming devices have MDSS.)  And
then external to the display controller are HDMI, DSI, etc. blocks which
may be shared across devices which have different display controller
blocks.

To more easily add support for different display controller blocks, the
display controller specific bits are split out into a "kms" module,
which provides the kms plane/crtc/encoder objects.

The external HDMI, DSI, etc. blocks are part encoder, and part connector
currently.  But I think I will pull in the drm_bridge patches from
chromeos tree, and split them into a bridge+connector, with the
registers that need to be set in modeset handled by the bridge.  This
would remove the 'msm_connector' base class.  But some things need to be
double checked to make sure I could get the correct ON/OFF sequencing..

This patch adds support for mdp4 crtc (including hw cursor), dtv encoder
(part of MDP4 block), and hdmi.

Keep this split out as a separate commit to make it easier to review the
