Maxime Ripard 56fe8b6f49 drm/bridge: Add RGB to VGA bridge support
Some boards have an entirely passive RGB to VGA bridge, based on DACs
implemented by resistor ladders.

Those might or might not have an i2c bus routed to the VGA connector in
order to access the screen EDIDs.

Add a bridge that doesn't do anything but expose the modes available on the
screen, either based on the EDIDs if available, or based on the XGA
standards.

Archit Taneja 5f6f5e08b1 drm/msm/hdmi: Clean up HDMI gpio DT bindings
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.

Jyri Sarha 7e567624dc drm/i2c: tda998x: Register ASoC hdmi-codec and add audio DT binding
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.

Jyri Sarha bcc5a6f5fc drm/tilcdc: Add blue-and-red-crossed devicetree property
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.

For more details see section 3.1.1 in AM335x Silicon Errata:

Milo Kim 05b01dd936 ARM: dts: exynos: Use 'hpd-gpios' instead of 'hpd-gpio'
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 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.

Archit Taneja 9097209d4d dt-bindings: msm/dsi: Add assigned clocks bindings
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.

This set of changes contains a bunch of cleanups to the host1x driver as
 well as the addition of a pin controller for DPAUX, which is required by
 boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C
 mode (for HDMI and DDC).
 
 Included is also a bit of rework of the SOR driver in preparation to add
 DisplayPort support as well as some refactoring and cleanup.
 
 Finally, all output drivers are converted to runtime PM, which greatly
 simplifies the handling of clocks and resets.

Included is also a bit of rework of the SOR driver in preparation to add
DisplayPort support as well as some refactoring and cleanup.

Finally, all output drivers are converted to runtime PM, which greatly
simplifies the handling of clocks and resets.

Thierry Reding 5d2304c1de dt-bindings: display: tegra: Add source clock for SOR
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.

Jon Hunter 6cb68e46a9 dt-bindings: Add bindings for Tegra DPAUX pinctrl 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.
