git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into drm-next
ZTE DRM driver updates for 4.11:
- Add missing selection of VIDEOMODE_HELPERS in Kconfig, since ZTE DRM
driver uses drm_display_mode_to_videomode().
- Enable HDMI audio support through SPDIF interface based on generic
hdmi-audio-codec driver.
- Enable VOU VL (Video Layer) to support overlay plane with scaling
function.
- Refine zx_vou driver a bit and then add TV Encoder output device
support.

It enables VOU VL (Video Layer) to support overlay plane with scaling
function. VL0 has some quirks on scaling support. We choose to skip it
and only adds VL1 and VL2 into DRM core for now.
Function zx_plane_atomic_disable() gets moved around with no changes to
save a forward declaration.

There are a few hardware bits for each graphic layer to control main/aux
channel and clock selection, as well as the layer enabling. These bits
sit outside the layer block itself, but in VOU control glue block. We
currently set these bits up at CRTC initialization for once, and do not
support disabling the layer.
This patch creates a pair of functions zx_vou_layer_enable[disable] to
be invoked from plane hooks .atomic_update and .atomic_disable to set up
and tear down the layer. This is generic for both graphic and video
layers, so it will make the overlay plane support to be added later much
easier.

Move struct zx_plane from zx_plane.c to zx_plane.h, so that it can be
accessed from zx_vou driver, and we can save the use of struct
zx_layer_data completely. More importantly, those additional data used
by VOU controller to enable/disable graphic and video layers can later
be added and accessed much more easily from zx_vou driver.
While at it, we make two changes to zx_plane_init() interface:
- Encode struct device pointer in zx_plane, so that we do not need to
pass it as a parameter.
- Change return of zx_plane_init() from struct drm_plane pointer to
error code, since we can get the pointer from zx_plane in zx_vou
driver now.

Replace uses of fb->pixel_format with fb->format->format.
Less duplicated information is a good thing.
Note that coccinelle failed to eliminate the
"/* fourcc format */" comment from drm_framebuffer.h, so I had
to do that part manually.

ZTE zxdrm driver support for 4.10:
This is the initial ZTE VOU display controller DRM/KMS driver. There
are still some features to be added, like overlay plane, scaling, and
more output devices support. But it's already useful with dual CRTCs
and HDMI display working.
[airlied: use drm_format_plane_cpp instead of legacy api]
