User may send null commit without any plane attached to kernel.
In kernel, these null commits will clear mixer blendstage for
all pipes, and power on screen with black background color.
However, when bootloader splash is on, this operation will
override the splash, which brings long black screen duration
between splash and user UI. So this patch is to fix this.

Add new DRM node to handle early display service. The early DRM
driver is to workaround Andriod display framework long boot time
problem and DRM single master limitation. The early DRM node provides
display function for early application that is outside Android
framework. The early application can use early DRM to draw early
UI and bootloader review camera menu function. Android framework will
not use early DRM node. It will continue to use the main DRM node.
Early DRM is another KMS driver that designed for bootup application.
Early DRM is not based on SDE framework and it will not initialize
display hardware. Early DRM rely on bootloader to initialize display
hardware and interfaces. For power and SMMU, early DRM relies on main
DRM to initialize them. Early DRM only provide limited display
functionality such as RGB buffer display. Early DRM only expected to
run during bootup time to work with bootloader/early RVC. When Android
UI is ready, early DRM will handoff all display resource to main DRM.
After that, no application can open early DRM node.
Early DRM is enabled in device tree. User must specify which display
to enable early DRM and which display pipes are assigned to eDRM.

Need to read register block length from the DTSI and populate
into the catalog to support register debug dumping. Also add a

This change adds the secure context bank child node in mdss
driver, this is required for having both the secure and non-secure
smmu context bank support in the driver. This change also renames
the child nodes to avoid compilation issues on the builds where
fb driver mdss device file is also present. As a part of this
change the smmu driver registration is called as a part of
msm driver probe.

This CEC adapter driver using CEC framework provides CEC
support for SDE hardware. CEC is a protocol that provides
high-level control functions between various audiovisual
products. This adapter is the hardware implementation of
CEC protocol, and its major functionality is to send and
to receive CEC messages.

The power handle driver parses the regulator and
clocks present on certain device node and it votes/enables
the clock when client request for it. Multiple clients
can request for enable/disable at the same time. It handles
the reference counting logic to avoid removal vote from
other client. It also supports the register bus driver
voting. Data bus driver support is still missing.

Pull drm updates from Dave Airlie:
"I Was Almost Tempted To Capitalise Every Word, but then I decided I
couldn't read it myself!
I've also got one pull request for the sti driver outstanding. It
relied on a commit in Greg's tree and I didn't find out in time, that
commit is in your tree now so I might send that along once this is
merged.
I also had the accidental misfortune to have access to a Skylake on my
desk for a few days, and I've had to encourage Intel to try harder,
which seems to be happening now.
Here is the main drm-next pull request for 4.4.
Highlights:
New driver:
vc4 driver for the Rasberry Pi VPU.
(From Eric Anholt at Broadcom.)

This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
