There are display panels which demands that the sync signal is driven on
different edge than the pixel data.
With the syncclk-active property we can specify the clk edge to be used to
drive the sync signal. When the property is missing it indicates that the
sync is driven on the same edge as the pixel data.

The A31's display pipeline has 2 frontends, 2 backends, and 2 TCONs. It
also has new display enhancement blocks, such as the DRC (Dynamic Range
Controller), the DEU (Display Enhancement Unit), and the CMU (Color
Management Unit). It supports HDMI, MIPI DSI, and 2 LCD/LVDS channels.
The A31s display pipeline is almost the same, just without MIPI DSI.
Only the TCON seems to be different, due to the missing mux for MIPI
DSI.
Add compatible strings for both of them.

The A31 TCON has mux controls for how TCON outputs are routed to the
HDMI and MIPI DSI blocks.
Since the A31s does not have MIPI DSI, it only has a mux for the HDMI
controller input.
This patch only adds support for the compatible strings. Actual support
for the mux controls should be added with HDMI and MIPI DSI support.

The change adds support of internal HDMI I2C master controller, this
subdevice is used by default, if "ddc-i2c-bus" DT property is omitted.
The main purpose of this functionality is to support reading EDID from
an HDMI monitor on boards, which don't have an I2C bus connected to
DDC pins.
The current implementation does not support "I2C Master Interface
Extended Read Mode" to read data addressed by non-zero segment
pointer, this means that if EDID has more than 1 extension blocks,
EDID reading operation won't succeed, in my practice all tested HDMI
monitors have at maximum one extension block.

Make the following changes in the HDMI gpio bindings:
- Use "-gpios" as the suffix for all the gpio names
- Move all the gpios to optional, since there are platforms that use none
of them.
- The HPD gpio is a standard one, remove the "qcom,hdmi-tx-" prefix from
it.
- Remove the HDMI DDC clk/data gpios. They are just leftovers of an old
way to configure pinctrl properties.
- Add a missing lpm gpio used on some platforms.
Make the necessary changes in the driver to incorporate these changes.
There hasn't been any upstream DT that uses the HDMI bindings, so it's
okay to change and move around these properties.

Register ASoC HDMI codec for audio functionality and adds device tree
binding for audio configuration.
With the registered HDMI codec the tda998x node can be used like a
regular codec node in ASoC card configurations. HDMI audio info-frame
and audio stream header is generated by the ASoC HDMI codec. The codec
also applies constraints for available sample-rates based on Edid Like
Data from the display. The device tree binding document has been
updated [1].
Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x:
Add support of a DT graph of ports"-patch [2]. There may still be some
identical lines left from the original patch and some of the ideas
have come from there.

Add "blue-and-red-wiring"-device tree property and update devicetree
binding document.
The red and blue components are reversed between 24 and 16 bit modes
on am335x LCDC output pins. To get 24 RGB format the red and blue
wires has to be crossed and this in turn causes 16 colors output to be
in BGR format. With straight wiring the 16 color is RGB and 24 bit is
BGR.
The new property describes whether the red and blue wires are crossed
or not. If the property is not present or its value is not recognized
the legacy mode is assumed. The legacy configuration supports RGB565,
RGB888 and XRGB8888 formats. However, depending on wiring, the red and
blue colors are swapped in either 16 or 24-bit color modes.

This patch enables getting a HPD GPIO descriptor quicker.
The exynos-hdmi driver uses "hpd" for HDMI hot plug detection.
static int hdmi_resources_init(struct hdmi_context *hdata)
{
...
hdata->hpd_gpio = devm_gpiod_get(dev, "hpd", GPIOD_IN);
...
}
This calls 'of_find_gpio()' and it generates the GPIO consumer ID by referring
GPIO suffix. So 'hpd-gpios' is preferred on getting a GPIO descriptor.
However, if the device tree uses 'hpd-gpio', then the exynos-hdmi driver
always retries to get a GPIO descriptor because the first GPIO suffix is not
'gpio' but 'gpios'. So you always see the debug message below.
of_get_named_gpiod_flags: can't parse 'hpd-gpios' property of node '/soc/hdmi@14530000[0]'
Use the preferred property, 'hpd-gpios' instead of 'hpd-gpio'.

This adds drm bridge support for the NXP/Freescale DCU. The patchset
has been discussed on the mailing list since quite some time...
Plus there is a small fix provided by Peter.
* 'for-next' of http://git.agner.ch/git/linux-drm-fsl-dcu:
drm/fsl-dcu: add support for drm bridge
drm/fsl-dcu: rework codes to support of_graph dt binding for panel
drm/fsl-dcu: add missing of_node_put after calling of_parse_phandle
This is an update to the previous drm bridge pull request. The ADV7511
driver's conversion from slave encoder to bridge meant that its users
(the rcar-du kms driver) should use the bridge interface too. This pull
request now also contains a commit that updates the rcar-du's hdmi encoder
interface from slave encoder to bridge.
The other updates are as before:
- Converts the ADV7511 i2c slave encoder driver to a bridge driver.
Adds support for the ADV7533 bridge chip.
- Add bridge driver for TC358767 (DSI/DPI to eDP) encoder chips.
* 'drm_bridge_for_4.8' of https://github.com/boddob/linux:
drm: rcar-du: Remove i2c slave encoder interface for hdmi encoder
drm/bridge: tc358767: Add DPI to eDP bridge driver

The MDP4/5 DT node now contains a list of ports that describe how it
connects to external encoder interfaces like DSI and HDMI. These follow
the standard of_graph bindings, and allow us to get rid of the 'connectors'
phandle that contained a list of all the external encoders connected to
MDP.

The PLL in the DSI PHY block generates 2 clock outputs (Byte and Pixel
clocks) that are fed into the Multimedia Clock Controller (MMCC). The MMCC
uses these as source clocks for some of its RCGs to generate clocks that
finally feed to the DSI host controller.
Use the assigned clocks DT bindings to set up the MMCC RCGs that feed to
the DSI host. Use the DSI PHY provided clocks to set up the parents
of these assigned clocks.

The "qcom,data-lane-map" binding mentioned in the document is changed to
the more generic "data-lanes" property specified in:
Documentation/devicetree/bindings/media/video-interfaces.txt
The previous binding expressed physical to logical data lane mappings,
the standard "data-lanes" binding uses logical to physical data lane
mappings. Update the docs to reflect this change. The example had the
property incorrectly named as "lanes", update this too.
The MSM DSI DT bindings aren't used anywhere at the moment, so
it's okay to update this property.

The SOR clock can have various sources, with the most commonly used
being the sor_safe, pll_d2_out0, pll_dp and sor_brick clocks. These
are configured using a three level mux, of which the first 2 levels
can be treated as one. The direct parents of the SOR clock are the
sor_safe, sor_brick and sor_src clocks, whereas the pll_d2_out0 and
pll_dp clocks can be selected as parents of the sor_src clock via a
second mux.
Previous generations of Tegra have only supported eDP and LVDS with
the SOR, where LVDS was never used on publicly available hardware.
Clocking for this only ever required the first level mux (to select
between sor_safe and sor_brick).
Tegra210 has a new revision of the SOR that supports HDMI and hence
needs to support the second level mux to allow selecting pll_d2_out0
as the SOR clock's parent. This second mux is knows as sor_src, and
operating system software needs a reference to it in order to select
the proper parent.

registers, we need to enable the pclk_vio_grf which supply power for VIO
GRF IOs, so it's better to introduce an optional grf clock in driver.

On Tegra124, Tegra132 and Tegra210 devices the pads used by the Display
Port Auxiliary (DPAUX) channel are multiplexed such that they can also
be used by one of the internal I2C controllers. Note that this is
different from I2C-over-AUX supported by the DPAUX controller. The
register that configures these pads is part of the DPAUX controllers
register set and so a pinctrl driver is being added for the DPAUX device
to share these pads. Add the device-tree binding documentation for the
DPAUX pad controller.
Although there is only one group of pads associated with the DPAUX that
can be multiplexed, the group still needs to be described by the binding.
If the 'groups' property is not present in the binding, then the pads
will not be allocated by the pinctrl core for a client and this would
allow another client to re-configure the same pads that may already be
in-use.
Please note that although the "off" function for the DPAUX pads is not
technically a pin-mux setting but more of a pin-conf setting it is
simpler to expose these as a function so that the user can simply select
either "aux", "i2c" or "off" as the current function/mode.
Update the main DPAUX binding documentation to reference the DPAUX pad
controller binding document and add the 'i2c-bus' subnode. The 'i2c-bus'
subnode is used for populating I2C slaves for the DPAUX device so that
the I2C driver core does not attempt to add the DPAUX pad controller
nodes as I2C slaves.

Summary:
- Support for pipeline clock between KMS drivers.
. Exynos SoC is required to control clocks across KMS drivers
according to Exynos SoC version. So this patch refactos
some relevant codes and provides generic solution for it.
- Add Exynos5433 SoC support to HDMI parts - HDMI and DECON-TV.
- Add HW trigger mode support to CRTC drivers.
. In case of using i80 Panel, some Exynos SoC supports HW trigger
mode so this patch makes trigger mode - HW or SW trigger - to be
set according to SoC version properly.
- And some cleanups and regression fixups.

This contains a refactoring of parts of the DSI core to allow creating
DSI devices from non-DSI control busses (i.e. I2C, SPI, ...).
Other than that there's support for a couple of new panels as well as
a few cleanup patches.

drm/panel: Changes for v4.6-rc1
This contains a refactoring of parts of the DSI core to allow creating
DSI devices from non-DSI control busses (i.e. I2C, SPI, ...).
Other than that there's support for a couple of new panels as well as
a few cleanup patches.
* tag 'drm/panel/for-4.6-rc1' of http://anongit.freedesktop.org/git/tegra/linux:
drm/bridge: Make (pre/post) enable/disable callbacks optional
drm/panel: simple: Add URT UMSH-8596MD-xT panels support
dt-bindings: Add URT UMSH-8596MD-xT panel bindings
of: Add United Radiant Technology Corporation vendor prefix
drm/panel: simple: Support for LG lp120up1 panel
dt-bindings: Add LG lp120up1 panel bindings
drm/panel: simple: Fix g121x1_l03 hsync/vsync polarity
drm/dsi: Get DSI host by DT device node
drm/dsi: Add routine to unregister a DSI device
drm/dsi: Try to match non-DT DSI devices
drm/dsi: Use mipi_dsi_device_register_full() for DSI device creation
drm/dsi: Check for CONFIG_OF when defining of_mipi_dsi_device_add()
Big ticket items are hdmi support for 8996 (aka snapdragon 820), and
adreno 430 support. Also one more small uapi addition to support
timestamp queries.

dt-bindings: msm/hdmi: Add HDMI PHY bindings
...
The DSI driver is currently unaware of how the DSI physical data lanes
are mapped to the logical lanes provided by the DSI controller.
Create a DT binding "qcom,data-lane-map" that provides this information
on a given platform.
The MSM DSI controller is restricted in terms of what all mappings
it can support. The lane polarity is fixed for all the lanes, the clock
lanes are fixed, and the data lanes can be swapped among each other only
for a few combinations. Apply these restrictions when we parse the DT
data.

Add HDMI PHY bindings. Update the example to use HDMI PHY.
Added a missing power-domains property in the HDMI core bindings. Also,
simplified HDMI TX's DT node name in the example.
