The msm Makefile and Kconfig are getting conjusted. HDMI is going to
have more configs and files in the future to manage, which will make
managing these harder.
Move hdmi related stuff into separate Kconfig and Makefile.

Make gpio allocation and usage iterative by parsing the gpios on a given
platform from a list. This gives us flexibility over what all gpios exist
for a platform, whether they are input or output, and what value they
should be set to.
In particular, this will make hdmi on 8x96 platforms easier to integrate
with the driver, as it doesn't have a hpd gpio input to them. Also, it
cleans things up a bit.
We still use the legacy gpio api here, as we might need to backport this
driver to downstream kernels.

Some platforms may not have a hpd gpio line to detect hpd. They need to
rely only on reading REG_HDMI_HPD_INT_STATUS for hpd.
Modify hdmi_connector_detect logic such that it checks for hpd only using
the status register if there is no hpd gpio.

Create a phy device that represents the TX PHY and PLL parts of the hdmi
block.
This makes management of PHY specific resources (regulators and clocks)
much easier, and makes the PHY and PLL usable independently. It also
simplifies the core hdmi driver, which currently assigns phy ops among
with many other things.
The phy driver implementation done here is very similar to the phy driver
we already have for DSI.
Keep the old hdmi_phy_funcs ops for now. These will be removed later.

Make hdmi core get its phy by parsing the qcom,hdmi-phy phandle. The core
will use this phy reference to enable/disable phy. The driver defers probe
until phy isn't available.

To: robdclark; +Cc: linux-arm-msm, dri-devel, Archit Taneja
Add a helper to initialize PLL in the phy driver.
HDMI PLLs are going to have their own mmio base different from that of
PHY.
For the clock code in hdmi_phy_8960.c, some changes were needed for it to
work with the updated register offsets. Create a copy of the updated clock
code in hdmi_pll_8960.c, instead of rewriting it in hdmi_phy_8960.c
itself. This removes the need to place CONFIG_COMMON_CLOCK checks all
around, makes the code more legible, and also removes some old checkpatch
warnings with the original code.
The older hdmi pll clock ops in hdmi_phy_8960.c will be removed later.

Remove the old phy ops managed by hdmi_platform_config and use them as ops
provided by the hdmi phy driver.
Remove the old hdmi 8960 PLL code that used the top level hdmi tx mmio
base.

Adds hdmi 8996 phy offsets. The offsets are divided into 3 parts:
- Core HDMI PHY registers
- HDMI PLL registers (part of QSERDES block)
- HDMI TX lane registers (part of QSERDES block)

To: robdclark; +Cc: linux-arm-msm, dri-devel, Archit Taneja
Add support for the HDMI PHY/PLL found in msm8996/apq8096.
Unlike the previous phys supported in the driver, this doesn't need
the powerup/powerdown ops. The PLL prepare/unprepare clock ops
enable/disable the phy itself.

Sorry, this is a typo. It should be qcom,hdmi-phy.

The PHY in the HDMI and DSI blocks can't be implemented using the
common phy framework. The PHY blocks have a PLL sub-block within
them which acts as a pixel clock source for the display processor
block.
This dependency causes the need to split the phy power on sequence
into 2 parts (one to enable resources to enable the PLL, and the
other to enable the phy itself), which the phy framework can't
do. That's the main reason not to use it. There are some more
complex use cases for DSI PHY (drive two PHYs with the same
DSI PLL) which the phy framework can't support.
Thanks,
Archit
