Shawn Guo 98ae9869d1 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.

Shawn Guo 83d7115250 drm: zte: support hdmi audio through spdif
It enables HDMI audio support through SPDIF interface based on generic
hdmi-audio-codec driver.  The HDMI hardware supports more audio
interfaces than SPDIF, like I2S, which may be added later.

Dan Carpenter 72282a88d4 drm: zte: checking for NULL instead of IS_ERR()
drm_dev_alloc() never returns NULL, it only returns error pointers on
error.

Dave Airlie d8c1abd968 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.
