Add a standard optional properties to support different non RGB color
encodings in DRM planes. COLOR_ENCODING select the supported non RGB
color encoding, for instance ITU-R BT.709 YCbCr. COLOR_RANGE selects
the value ranges within the selected color encoding. The properties
are stored to drm_plane object to allow different set of supported
encoding for different planes on the device.

While A83T HDMI PHY seems to be just customized Synopsys HDMI PHY, H3
HDMI PHY is completely custom PHY.
However, they still have many things in common like clock and reset
setup, setting sync polarity and more.
Add support for H3 HDMI PHY variant.
While documentation exists for this PHY variant, it doesn't go in great
details. Because of that, almost all settings are copied from BSP linux
4.4. Interestingly, those settings are slightly different to those found
in a older BSP with Linux 3.4. For now, no user visible difference was
found between them.

Current polarity configuration code is cleary wrong since it compares
same flag two times. However, even if flag name is fixed, it won't work
well for resolutions which have one polarity positive and another
negative.
Fix that by properly set each bit according to each polarity. Since
those two bits are not described in any documentation, relationships
were obtained by experimentation.

around in unbind, first unbind the analogix_dp and then

The driver that instantiates the bridge should own the drvdata, as all
driver model callbacks (probe, remove, shutdown, PM ops, etc.) are also
owned by its driver struct. Moreover, storing two different pointer
types in driver data depending on driver initialization status is barely
a good practice and in fact has led to many bugs in this driver.
Let's clean up this mess and change Analogix entry points to simply
accept some opaque struct pointer, adjusting their users at the same
time to avoid breaking the compilation.

Currently we are calling scl_vop_cal_scale() to get vskiplines for yrgb

second scl_vop_cal_scale() didn't update it.

Calling devm_of_find_backlight directly means we get a link failure

mi0283qt.c:(.text+0x684): undefined reference to `devm_of_find_backlight'
This adds an explicit Kconfig dependency for it. While I did not
observe that failure for st7735r, I assume the same change is needed
there for the same reason.

DRM_DUMB_VGA_DAC is a user-visible symbol. Selecting it can cause unmet
direct dependencies such as this (on i386, randconfig):
warning: (DRM_PL111) selects DRM_DUMB_VGA_DAC which has unmet direct dependencies (HAS_IOMEM && DRM && DRM_BRIDGE && OF)
This is because DRM_DUMB_VGA_DAC depends on OF while DRM_PL111 does not.
It does indirectly depend on OF via the ARM and ARM64 dependencies, but
since it can also be enabled under COMPILE_TEST, randconfig can find a
case where DRM_PL111 is selected without pulling in OF and not meeting
the dependency for DRM_DUMB_VGA_DAC.
Since select is "heavy handed", DRM_DUMB_VGA_DAC is going to be enabled
regardless of the above warning and causes the following build error:
../drivers/gpu/drm/bridge/dumb-vga-dac.c: In function 'dumb_vga_probe':
../drivers/gpu/drm/bridge/dumb-vga-dac.c:207:13: error: 'struct drm_bridge' has no member named 'of_node'

If simple_kms_helper based driver needs to work with vblanks,
then it has to provide drm_driver.{enable|disable}_vblank callbacks,
because drm_simple_kms_helper.drm_crtc_funcs does not provide any.
At the same time drm_driver.{enable|disable}_vblank callbacks
are marked as deprecated and shouldn't be used by new drivers.
Fix this by extending drm_simple_kms_helper.drm_crtc_funcs
to provide the missing callbacks.

When comparing two variables with min()/max(), they should be the same type:
drivers/gpu/drm/drm_memory.c: In function 'drm_get_max_iomem':
include/linux/kernel.h:821:16: error: comparison of distinct pointer types lacks a cast [-Werror]
(void) (&max1 == &max2);
This makes the local variable in drm_get_max_iomem make the type
from resource->end.

It is possible that drm_simple_kms_plane_atomic_check called
with no CRTC set, e.g. when user-space application sets CRTC_ID/FB_ID
to 0 before doing any actual drawing. This leads to NULL pointer
dereference because in this case new CRTC state is NULL and must be
checked before accessing.

We've had some code for quite some time to prevent the alpha bug from
happening on the lowest primary plane. Since we now check for this in our
atomic_check, we can simply remove it.

The plane description structure was mostly needed to differentiate the
formats usable on the primary plane (because of its lowest position), and
assign the pipes. Now that both are dynamically checked and assigned, we
can remove the static definition.

Since we now have a way to enforce the zpos, check for the number of alpha
planes, the only missing part is to assign our pipe automatically instead
of hardcoding it.
The algorithm is quite simple, but requires two iterations over the list of
planes.
In the first one (which is the same one that we've had to check for alpha,
the frontend usage, and so on), we order the planes by their zpos.
We can then do a second iteration over that array by ascending zpos
starting with the pipe 0. When and if we encounter our alpha plane, we put
it and all the other subsequent planes in the second pipe.

a generic of_find_backlight defined in backlight.c. Let the callers

select BACKLIGHT_LCD_SUPPORT and select BACKLIGHT_CLASS_DEVICE from
tinydrm/Kconfig as it is a hack that is no longer needed.

Move it out of the csv dungeon.
While at it add the missing link to the helper functions for setting

Also OCD how we list enum property values and their corresponding docs.
Going for a nest definition list seams cleanest, no need for also making
it an uordered list.
