The horizontal blanking periods are too short, as the values are
specified for a single LVDS channel. Since this panel is dual LVDS
they need to be doubled. With this change the panel reaches its
nominal vrefresh rate of 60Fps, instead of the 64Fps with the
current wrong blanking.

Philipp Zabel added:
The datasheet specifies 960 active clocks + 40/128/160 clocks blanking
on each of the two LVDS channels (min/typical/max), so doubled this is
now correct.

The AUO b101ean01's datasheet says:
* Vertical blanking min is 12
* Horizontal blanking min is 60
* Pixel clock is between 65.3 MHz and 75 MHz

The goal here is to be able to specify the proper timing in device

kernel is using so that it can used the fixed PLL.

Convert the Innolux n116bge from using a fixed mode to specifying a
display timing with min/typ/max values.

Note that the n116bge's datasheet doesn't fit too well into DRM's way
of specifying things.  Specifically the panel's datasheet just
specifies the vertical blanking period and horizontal blanking period
and doesn't break things out.  For now we'll leave everything as a
fixed value but just allow adjusting the pixel clock.  I've added a
comment on what the datasheet claims so someone could later expand
things to fit their needs if they wanted to test other blanking
periods.

The goal here is to be able to specify the panel timings in the device
tree for several rk3288 Chromebooks (like rk3288-veryon-jerry).  These
Chromebooks have all been running in the downstream kernel with the
standard porches and sync lengths but just with a slightly slower
pixel clock because the 76.42 MHz clock is not achievable from the
fixed PLL that was available.  These Chromebooks only achieve a
refresh rate of ~58 Hz.  While it's probable that we could adjust the
timings to achieve 60 Hz it's probably wisest to match what's been
running on these devices all these years.

I'll note that though the upstream kernel has always tried to achieve
76.42 MHz, it has actually been running at 74.25 MHz also since the
video processor is parented off the same fixed PLL.

 - display_timing for Innolux n116bge new for v4.

 - Added Heiko's Tested-by

This patch adds the ability to override the typical display timing for a
given panel. This is useful for devices which have timing constraints
that do not apply across the entire display driver (eg: to avoid
crosstalk between panel and digitizer on certain laptops). The rules are
as follows:

- panel must not specify fixed mode (since the override mode will
  either be the same as the fixed mode, or we'll be unable to
  check the bounds of the overried)
- panel must specify at least one display_timing range which will be
  used to ensure the override mode fits within its bounds

Changes in v2:
 - Parse the full display-timings node (using the native-mode) (Rob)
Changes in v3:
 - No longer parse display-timings subnode, use panel-timing (Rob)
Changes in v4:
 - Don't add mode from timing if override was specified (Thierry)
 - Add warning if timing and fixed mode was specified (Thierry)
 - Don't add fixed mode if timing was specified (Thierry)
 - Refactor/rename a bit to avoid extra indentation from "if" tests
 - i should be unsigned (Thierry)
 - Add annoying WARN_ONs for some cases (Thierry)
 - Simplify 'No display_timing found' handling (Thierry)
 - Rename to panel_simple_parse_override_mode() (Thierry)

As a preparation work for introducing writeback to vkms, this patch
renames the file vkms_crc.c into vkms_composer.c. Accordingly, it also
adjusts the functions and data structures to match the changes.

No functional change.

When vkms invoke drm_universal_plane_init(), it sets 0 for
possible_crtcs parameter which means that planes can't be attached to
any CRTC. It currently works due to some safeguard in the drm_crtc file;
however, it is possible to identify the problem by trying to append a
second connector. This patch fixes this issue by modifying
vkms_plane_init() to accept an index parameter which makes the code a
little bit more flexible and avoid set zero to possible_crtcs.

Only dynamic mode objects, i.e. those which are refcounted and have a free
callback, can be added while the overall drm_device is visible to
userspace. All others must be added before drm_dev_register and
removed after drm_dev_unregister.

Small issue around drivers still using the load/unload callbacks, we
need to make sure we set dev->registered so that load/unload code in
these callbacks doesn't trigger false warnings. Only a small
adjustement in drm_dev_register was needed.

Motivated by some irc discussions about object ids of dynamic objects
like blobs become invalid, and me going on a bit an audit spree.

The function drm_client_close is declared as static and marked as
EXPORT_SYMBOL. It's a bit confusing for an internal function to be
exported. The area of visibility for such function is its .c file
and all other modules. Other *.c files of the same module can't use it,
despite all other modules can. Relying on the fact that this is the
internal function and it's not a crucial part of the API, the patch
removes the EXPORT_SYMBOL marking of drm_client_close.
