7204e97685 drm: adv7511_audio: Add .get_dai_id callback to map port number to dai id
ALSA SoC needs to know connected DAI ID for probing. Using
the new audio-card-graph approach, ports/endpoints are used
to describe how the links are connected. Unfortunately, since
ports/endpoints are used as well for video linkages, there
are some issues mixing the port ids to the two (video and
audio) namespaces.

To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.

The will assume that HDMI audio out will be connected to
reg = <2>. This will then be remapped to the ALSA SoC side will
as DAI 0. Allowing the adv7511's hdmi audio support to be used
with the audio-card-graph.

Credit to Kuninori Morimoto who's patch to dw-hdmi-i2s-audio.c
was what this was mostly copy-pasted from.

e3839bd6f5 drm: dw-hdmi-i2s: add .get_dai_id callback for ALSA SoC
ALSA SoC needs to know connected DAI ID for probing.
It is not a big problem if device/driver was only for sound,
but getting DAI ID will be difficult if device includes both
Video/Sound, like HDMI.
To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.
dw-hdmi-i2s will assume that HDMI sound will be connected
to reg = <2>. Then, ALSA SoC side will recognized it as DAI 0

	ports {
		#address-cells = <1>;
		#size-cells = <0>;
		port@0 {
			reg = <0>;
			/* HDMI Video IN */
		};
		port@1 {
			reg = <1>;
			/* HDMI OUT */
		};
		port@2 {
			reg = <2>;
			/* HDMI Sound IN */
		};
	};

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.11.

  Nothing too major, the tinydrm and mmu-less support should make
  writing smaller drivers easier for some of the simpler platforms, and
  there are a bunch of documentation updates.

  Intel grew displayport MST audio support which is hopefully useful to
  people, and FBC is on by default for GEN9+ (so people know where to
  look for regressions). AMDGPU has a lot of fixes that would like new
  firmware files installed for some GPUs.

  Other than that it's pretty scattered all over.

  I may have a follow up pull request as I know BenH has a bunch of AST
  rework and fixes and I'd like to get those in once they've been tested
  by AST, and I've got at least one pull request I'm just trying to get

dc55ac3b52 drm/bridge: Add ti-tfp410 DVI transmitter driver
Add very basic ti-tfp410 DVI transmitter driver. The only feature
separating this from a completely dummy bridge is the EDID read
support trough DDC I2C. Even that functionality should be in a
separate generic connector driver. However, because of missing DRM
infrastructure support the connector is implemented within the bridge
driver. Some tfp410 HW specific features may be added later if needed,
because there is a set of registers behind i2c if it is connected.

This implementation is tested against my new tilcdc bridge support
and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document
is also updated.

3efc2fa3b7 drm: bridge/dw_hdmi: add dw hdmi i2c bus adapter 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.

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.

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

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.

5cff007c58 drm: bridge: analogix/dp: try force hpd after plug in lookup failed
Some edp screen do not have hpd signal, so we can't just return
failed when hpd plug in detect failed.

This is an hardware property, so we need add a devicetree property
"analogix,need-force-hpd" to indicate this sutiation.

efdbd7345f dt-bindings: consolidate display related bindings
This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
