The Allwinner SoCs have a display engine composed of several controllers
assembled differently depending on the SoC, the number and type of output
they have, and the additional features they provide. A number of those are
supported in Linux, with the matching bindings.
Now that we have the DT validation in place, let's split into separate file
and convert the device tree bindings for those controllers to schemas.

There is an increasing number of new simple panels.
Common for many of these simple panels are that they have one
mandatory power-supply and some of them have backlight and / or
an enable gpio.
The binding file to describe these panels adds overhead
that really do not add value.
The binding are known and there is nothing gained from a
dedicated binding file nor for any dedicated example.
The following patch introduces a single panel-simple.yaml
and converts two ampire bindings over to the new file.
The conversion - if applied will have following effects:
- The maintainer for the individual file will change
There is no need for many different maintainers for a simple binding.
We have the same situation with the panel-simple driver in the kernel.
- The license will change to (GPL-2.0-only OR BSD-2-Clause)
There is usually only a single line copied from the original
file, a line that is often copied from a datasheet.
This license change should be acceptable considered what little
is copied.
If the license change is not OK we can use a dedicated binding
file in these cases.
This is a follow-up on Rob's big patch converting a lot of panel bindings
to individual files:
"dt-bindings: display: Convert a bunch of panels to DT schema"
https://patchwork.ozlabs.org/patch/1197683/
The objectives with one file for the relevant simple panels are:
- Make it simpler to add bindings for simple panels
- Keep the number of bindings file lower and thus easier to find a
relevant file to copy from when adding new panels.
- Keep the binding documentation for simple panels more consistent
- Make it simpler to add support for new panels
v3:
- Whitespace fix (checkpatch)
- Indent compatible (Rob h)
- Indent comments to give compatible more visibility (Rob h)
v2:

- updated description (Rob)

The MIPI DSI controller in Allwinner A64 is similar to A33.
But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid
to have separate compatible for A64 on the same driver.
DSI_SCLK uses mod clock-names on dt-bindings, so the same
is not required for A64.
On that note
- A64 require minimum of 1 clock like the bus clock
- A33 require minimum of 2 clocks like both bus, mod clocks
So, update dt-bindings so-that it can document both A33,
A64 bindings requirements.

Sometimes we want to override a connector's panel_orientation from the
kernel commandline. Either for testing and for special cases, e.g. a kiosk
like setup which uses a TV mounted in portrait mode.
Users can already specify a "rotate" option through a video= kernel cmdline
option. But that only supports 0/180 degrees (see drm_client_modeset TODO)
and only works for in kernel modeset clients, not for userspace kms users.
The "panel-orientation" connector property OTOH does support 90/270 degrees
as it leaves dealing with the rotation up to userspace and this does work
for userspace kms clients (at least those which support this property).
Changes in v2:
-Add missing ':' after @panel_orientation (reported by kbuild test robot)
