Merge branch 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next

Hope I'm not too late before the cutoff for the v4.11 with these patches.
Mostly an asorted set of fixes that we have discovered while playing with
the code and preparing for the next set of features.

drm/atmel-hlcdc: Rework the fbdev creation logic

Now that we wait for DRM panels to be available before registering the
DRM device (returning -EPROBE_DEFER if the panel has not been probed
yet), we no longer need to put the fbdev creation code in
->output_poll_changed().

This removes the 10 secs delay between DRM dev registration and fbdev
creation (polling period = 10 seconds).

drm: zte: add tvenc driver support

It adds the TV Encoder driver to support video output in PAL and NTSC

The clock control module (CRM) cannot always provide desired frequency
for all VOU output devices.  That's why VOU integrates a few dividers
to further divide the clocks from CRM.  Let's add an interface for

drm: zte: move struct vou_inf into zx_vou driver

Although data in struct vou_inf is defined per output device, it doesn't
belong to the device itself but VOU control module.  All these data can
just be defined in VOU driver, and output device driver only needs to
invoke VOU driver function with device ID to enable/disable specific
output device.

drm: zte: add overlay plane 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.

drm: zte: add .atomic_disable hook to disable graphic layer

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.

drm: zte: make zx_plane accessible from zx_vou driver

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.

drm/amdgpu/gfx8: add support kernel interface queue(KIQ)

KIQ is queue-memory based initialization method: setup KIQ queue
firstly, then send command to KIQ to setup other queues, without
accessing registers.

For virtualization, need KIQ to access virtual function registers
when running on guest mode.

V2: use amdgpu_bo_create/free_kernel to allocate BO.
