Subject: drm/simple_kms_helper: Add {enable|disable}_vblank callback support

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.

Subject: drm/uapi: The ctm matrix uses sign-magnitude representation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The documentation for the ctm matrix suggests a two's complement
format, but at least the i915 implementation is using sign-magnitude
instead. And looks like malidp is doing the same. Change the docs
to match the current implementation, and change the type from __s64
to __u64 to drive the point home.

Subject: drm/bridge: analogix: Do not use device's drvdata

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.

MIME-Version: 1.0

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.

From 81af63a4af82e739aaa391d1fbb97e02c58ea6a1 Mon Sep 17 00:00:00 2001

Subject: drm: Don't pass clip to drm_atomic_helper_check_plane_state()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the plane clip rectangle handling into
drm_atomic_helper_check_plane_state(). Drivers no longer
have to worry about such mundane details.

v2: Convert armada, rcar, and sun4i as well
v3: Resolve simple_kms_helper conflict

Subject: drm/bridge: analogix_dp: Don't create useless connectors

If there is another bridge after analogix_dp, then the connector object
should not be created. This fixes following timeouts on Exynos5420-based
Chromebook2 Peach-PIT board during boot:

exynos-dp 145b0000.dp-controller: AUX CH cmd reply timeout!
exynos-dp 145b0000.dp-controller: AUX CH enable timeout!
exynos-dp 145b0000.dp-controller: AUX CH enable timeout!
exynos-dp 145b0000.dp-controller: AUX CH enable timeout!
exynos-dp 145b0000.dp-controller: AUX CH enable timeout!

Subject: drm/uapi: Deprecate DRM_MODE_PROP_PENDING
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DRM_MODE_PROP_PENDING is not used anywhere (except printed out
by libdrm proptest/modetest).

This seems to be yet another thing blindly copied from xrandr.
Quoting from the protocol spec:
"If 'pending' is TRUE, changes made to property values with
 RRChangeOutputProperty will be saved in the pending property value
 and be automatically copied to the current value on the next
 RRSetCrtcConfig request involving the named output. If 'pending' is
 FALSE, changes are copied immediately."

So it was some kind of early idea for atomic property updates.

Subject: drm: Make property flags u32
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The property flags are part of the uabi and we have 32 bits for them.
Pass them around as u32 internally as well, instead of a signed int.

Subject: drm/atomic: Add new reverse iterator over all plane state (V2)

Add reverse iterator for_each_oldnew_plane_in_state_reverse to
compliment the for_each_oldnew_plane_in_state way or reading plane
states.

The plane states are required to be read in reverse order for
amd drivers, cause the z order convention followed in linux is
opposite to how the planes are supposed to be presented to DC
engine, which is in common to both windows and linux.

V2: fix compile time errors due to -Werror flag.
