The DSI-HDMI converter, ADV7535, driver uses four i2c memory maps: MAIN,
DSI-CEC, EDID and PACKET.
While the MAIN address is hard-coded in the ROM chip, the other three
can be programmed into the MAIN memory map.
Currently, the three memory maps addresses, that can be programmed, are
hard-coded into the code.
In order to avoid conflicts with other i2c clients on the bus, update
the driver to use configurable addresses specified in DTS file.

Currently, the Northwest Logic MIPI-DSI controller host specific code
resides under drm/bridge, but is not a real drm_bridge. It creates a
drm_bridge and adds itself to the drm_encoder that handles this file,
but this is wrong, since it does not implement the drm_bridge_funcs.
The correct way to implement a drm_bridge is to add the drm_bridge and
let other components (another bridge or a drm_encoder) to attach to this
bridge.
Since we are doing this, a new compatible strings can be used for this
driver: "nwl,mipi-dsi".
Since this was used by nwl_dsi-imx.c, update that driver to use this
bridge correctly.
This is needed in order to add support for MIPI-DSI on 8MQ. The IMX_NWL
driver will either add a DSI encoder to DRM, or a DSI bridge.
The encoder will be used by imx-drm-core driver, while the bridge
will be used by MXSFB driver (which creates a simple display pipe).

Added "adi,adv7535" to the adv7511 drm bridge and adi,adv7511.txt doc,
since the driver can also support the ADV7535 chipset (upgrade of ADV7533).

Add support for the NorthWest Logit MIPI-DSI controller found in mx8
platforms: i.MX8qm, i.MX8qxp and i.MX8mq.
The NWL MIPI-DSI driver is implemented as a DRM bridge.
The MIPI-DSI encoder will contain the platform specific changes and will
use this bridge.

A low pulse whose width is at least 40ms on pin SYSRSTN
may reset the bridge, according to the chip maker.
This patch adds gpio reset support for the bridge.

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.

into drm-next
This adds the ASoC codec interfaces for TDA998x HDMI audio from
Jyri Sarha.
* 'drm-tda998x-devel' of git://git.armlinux.org.uk/~rmk/linux-arm:
ARM: dts: am335x-boneblack: Add HDMI audio support
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.

drm-next
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.

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.

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.
