Pull the drm_pci_agp_init() underneath the legacy ifdeffry alongside its
only caller.
The diff chooses it to so it by moving drm_pci_agp_destroy earlier, but
the important bit is moving the #ifdef earlier before drm_pci_agp_init.

This reverts commit 0f9cdd743f7f8d470fff51b11250f02fc554cf1b.
The interface of the panel is LVDS, not parallel.
The color depth is RGB888, not RGB565.
The panel has additional features, making it not so simple.
The only user (upstream) of this panel is appropriately using panel-lvds.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

convert the binding file rockchip-drm.txt to yaml format.
This was tested and verified on ARM and ARM64 with:
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/rockchip/rockchip-drm.yaml
Changes since v2:
- add a missing ">" sign in maintainers list
- change the licens to GPL-2.0-only
- add "additionalProperties: false"
- change the commit message to conform that it was tested on both ARM and ARM64

We try hard to select a suitable hole in the drm_mm first time. But if
that is unsuccessful, we then have to look at neighbouring nodes, and
this requires traversing the rbtree. Walking the rbtree can be slow
(much slower than a linear list for deep trees), and if the drm_mm has
been purposefully fragmented our search can be trapped for a long, long
time. For non-preemptible kernels, we need to break up long CPU bound
sections by manually checking for cond_resched(); similarly we should
also bail out if we have been told to terminate. (In an ideal world, we
would break for any signal, but we need to trade off having to perform
the search again after ERESTARTSYS, which again may form a trap of
making no forward progress.)

The qxl driver uses an empty implementation for its encoder. Replace
the code with the generic simple encoder.
v4:
* handle errors returned from drm_simple_encoder_init()
v2:
* rebase onto new simple-encoder interface

This patch makes the internal encoder implementation of the simple
KMS helpers available to drivers.
These simple-encoder helpers initialize an encoder with an empty
implementation. This covers the requirements of most of the existing
DRM drivers. A call to drm_simple_encoder_create() allocates and
initializes an encoder instance, a call to drm_simple_encoder_init()
initializes a pre-allocated instance.
v3:
* remove drm_simple_encoder_create(); not required yet
* provide more precise documentation
v2:
* move simple encoder to KMS helpers
* remove name argument; simplifies implementation
* don't allocate with devm_ interfaces; unsafe with DRM

The panel-dpi compatible is a fallback that
allows the DT to specify the timing.
When matching panel-dpi expect the device tree to include the
timing information for the display-panel.
Background for this change:
There are a lot of panels and new models hits the market very often.
It is a lost cause trying to chase them all and users of new panels
will often find them in situations that the panel they ues are not
supported by the kernel.
On top of this a lot of panels are customized based on customer
specifications.
Including the panel timing in the device tree allows for a simple
way to describe the actual HW and use this description in a generic
way in the kernel.
This allows uses of proprietary panels, or panels which are not
included in the kernel, to specify the timing in the device tree
together with all the other HW descriptions.
And thus, using the device tree it is then easy to add support
for an otherwise unknown panel.
The current support expect panels that do not require any
delays for prepare/enable/disable/unprepare.

I've just tested this patch on Apalis iMX6Q and Colibri iMX7D using
panel settings from the following patch:

It works for me, thanks!
