22a27e0532 drm/edid: start propagating drm_edid to lower levels 
We'll need to propagate drm_edid everywhere. This is a clunky start, but
a start nonetheless. We'll eventually convert all of the EDID parsing to
struct drm_edid.

Initially, we'll just create the struct drm_edid in stack. This will be
the compat layer for legacy struct edid code. In the future, we'll have
EDID read return drm_edid objects.

v2: Add legacy init helper.

e4ccf9a777 drm/edid: add struct drm_edid container 
Introduce new opaque type struct drm_edid to encapsulate the EDID data
and the size allocated for it. The contents will be private to
drm_edid.c.

There are a number of reasons for adding a container around struct edid:

* struct edid is a raw blob pointer to data that usually originates
  outside of the kernel. Its size is contained within the structure.

* There's no way to attach meta information (such as allocated memory
  size) to struct edid.

* Validation of the EDID blob and its size become crucial, and it's
  spread all over the subsystem, with varying levels of accuracy.

* HDMI Forum has introduced an HF-EEODB extension that defines an
  override EDID size within an EDID extension. The size allocated for an
  EDID depends on whether the allocator understands the HF-EEODB
  extension. Given a struct edid *, it's impossible to know how much
  memory was actually allocated for it.

There are also some reasons for making the container type struct
drm_edid opaque and private to drm_edid.c:

* Have only one place for creating and parsing the EDID, to avoid
  duplicating bugs.

* Prepare for reading a pure DisplayID 2.0 from its own DDC address, and
  adding it within the same struct drm_edid container, transparently,
  and for all drivers.

* With the idea that the drm_edid objects are immutable during their
  lifetimes, it will be possible to refcount them and reduce EDID
  copying everywhere (this is left for future work).

Initially, just add the type. In follow-up, we'll start converting the
guts of drm_edid.c to use it, and finally add interfaces around it.

fa0e256450 fbdev: vesafb: Allow to be built if COMPILE_TEST is enabled 
The driver has runtime but no build time dependency with X86, so it can
be built for testing purposes if the COMPILE_TEST option is enabled.

This is useful to have more build coverage and make sure that the driver
is not affected by changes that could cause build regressions.

3367aa7d74 fbdev: Restart conflicting fb removal loop when unregistering devices 
Drivers that want to remove registered conflicting framebuffers prior to
register their own framebuffer, call to remove_conflicting_framebuffers().

This function takes the registration_lock mutex, to prevent a race when
drivers register framebuffer devices. But if a conflicting framebuffer
device is found, the underlaying platform device is unregistered and this
will lead to the platform driver .remove callback to be called. Which in
turn will call to unregister_framebuffer() that takes the same lock.

To prevent this, a struct fb_info.forced_out field was used as indication
to unregister_framebuffer() whether the mutex has to be grabbed or not.

But this could be unsafe, since the fbdev core is making assumptions about
what drivers may or may not do in their .remove callbacks. Allowing to run
these callbacks with the registration_lock held can cause deadlocks, since
the fbdev core has no control over what drivers do in their removal path.

A better solution is to drop the lock before platform_device_unregister(),
so unregister_framebuffer() can take it when called from the fbdev driver.
The lock is acquired again after the device has been unregistered and at
this point the removal loop can be restarted.

Since the conflicting framebuffer device has already been removed, the
loop would just finish when no more conflicting framebuffers are found.

3080c21a04 drm/bridge: tc358767: Add DSI-to-(e)DP mode support 
Implement DSI-to-e(DP) mode, which is a mix of currently supported
DSI-to-DPI and DPI-to-(e)DP modes. The input side is configured as
either DSI or DPI, the DP AUX channel is registered for both input
side options, and the DSI host is attached for both DPI and (e)DP
output side options.

One notable detail is that the DSI-to-(e)DP mode requires the Pixel
PLL to be always enabled, which is not needed for DPI-to-(e)DP mode
which gets the matching clock direct from DPI Pixel Clock instead.

d7fd32ecce drm/bridge: tc358767: Factor out DSI and DPI RX enablement 
Factor out register programming to configure the chip video RX side for
reception of video data from DSI or DPI. This is particularly useful in
the (e)DP output mode, where the video data can be received from either
DPI or DSI. While only the former is supported in (e)DP output mode so
far, this patch is added in preparation for addition of the later.

There is a change in the order or register programming in case of the
DSI-to-DPI mode. The DSI RX side is now programmed and enabled all in
one place after the output mode has been configured. Before this change,
the DSI RX has been programmed before the output mode has been set and
only enabled afterward. The order makes no difference however, since the
DSI RX is only enabled at the end either way.

69ed3dd6be drm/bridge: nwl-dsi: Set PHY mode in nwl_dsi_mode_set() 
The Northwest Logic MIPI DSI host controller embedded in i.MX8qxp
works with a Mixel MIPI DPHY + LVDS PHY combo to support either
a MIPI DSI display or a LVDS display.  So, this patch calls
phy_set_mode() from nwl_dsi_mode_set() to set PHY mode to MIPI DPHY
explicitly.

6ff1c19f5f drm/edid: sunset drm_find_cea_extension() 
Convert drm_find_cea_extension() to a predicate function to check if the
EDID has a CTA extension or a DisplayID CTA data block. This is mainly
to avoid adding new users that only find the first CTA extension.

58304630b8 drm/edid: skip CTA extension scan in drm_edid_to_eld() just for CTA rev 
The DisplayID CTA data block version does not necessarily match the CTA
revision. Simplify by postponing drm_edid_to_eld() slightly, and reusing
the CTA revision extracted by drm_parse_cea_ext().

By not bailing out early in drm_edid_to_eld() we may end up filling
meaningless data to the ELD. However, the main decision for audio is not
the ELD, but rather drm_detect_monitor_audio() called by drivers.

(Arguably a future cleanup could do that in drm_add_edid_modes() and
cache the result in the connector.)
