Split up hdmi_init() into hdmi_init() (done at hdmi sub-device
bind/probe time) and hdmi_modeset_init() done from master driver's
modeset_init().
Anything that can fail due to dependencies on other drivers which
may be missing or not probed yet should go in hdmi_init(), so that
devm error/cleanup paths work properly.

There is currently a nested function in Russel King's tree
for the msm HDMI driver.
The last nested function was removed from the Linux kernel
when the Thinkpad driver was fixed.
I believe nested functions are not desired upstream, and it
also breaks compilation with clang so here is a patch to
change the nested function into static function. The patch
works with both clang and gcc.

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.

In particular, pick up the definitions for a handful of LVDS related

HDMI_MUX_EN gpio is requested. If an error occurs, the same name
should be printed (HDMI_MUX_EN) instead of HDMI_MUX_SEL (typo).

On downstream kernel the clk driver directly bangs hdmi phy registers.
For upstream kernel, we need to model this as a clock and register with
the clock framework.

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.

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().

Introduce generic functions to register and unregister connectors. This
provides a common place to add and remove associated user space

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.

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.

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.

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.
