drm/bridge: cdns: Separate DSI and D-PHY configuration
...
The current configuration of the DSI bridge and its associated D-PHY is
intertwined. In order to ease the future conversion to the phy framework
for the D-PHY part, let's split the configuration in two.

drm: Split out drm_probe_helper.h
...
Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

drm/bridge: cdns: prepare for drmP.h removal from drm_modeset_helper.h
...
The use of drmP.h is discouraged and removal of it from
drm_modeset_helper.h caused cdns to fail to build.
This patch introduce the necessary fixes to prepare for the
drmP.h removal from drm_modeset_helper.h.
Build tested on arm x86 and arm allmodconfig.

drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULL
...
Right now, the DRM panel logic returns NULL when a panel pointing to
the passed OF node is not present in the list of registered panels.
Most drivers interpret this NULL value as -EPROBE_DEFER, but we are
about to modify the semantic of of_drm_find_panel() and let the
framework return -ENODEV when the device node we're pointing to has
a status property that is not equal to "okay" or "ok".
Let's first patch the of_drm_find_panel() implementation to return
ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace
the '!panel' check by an 'IS_ERR(panel)' one.

drm/bridge: cdns: Mark runtime PM operations as maybe unused
...
Building the driver in a configuration with !PM currently causes a
warning about these operations being unused. Mark them as such to shut
up the compiler.

drm/bridge: Add Cadence DSI driver
...
Add a driver for Cadence DPI -> DSI bridge.
This driver only support a subset of Cadence DSI bridge capabilities.
This driver has been tested/debugged in a simulated environment which
explains why some of the features are missing. Here is a
non-exhaustive list of missing features:
* burst mode
* DPHY init/configuration steps
* support for additional input interfaces (SDI input)
DSI commands and non-burst video mode have been tested.
