[PATCH v3 0/3] Add initial ZTE VOU DRM/KMS driver

[Shawn Guo]

The series adds 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.

Changes for v3:
 - Rebase to v4.9-rc1
 - Update bindings doc to use 'ranges' for address translation between
   parent and child devices.
 - Call drm_dev_register() last in bind function and drm_dev_unregister()
   first in unbind, so that drm_connector_regiser() can be saved from
   HDMI driver.
 - Instead of using open-coded drm_do_get_edid(), add an I2C adapter for
   HDMI DDC read and use drm_get_edid().
 - Improve the plane .atomic_check implementation by calling helper
   function drm_plane_helper_check_state().
 - Rename zx_crtc.c to zx_vou.c to avoid the confusion that the file
   implements crtc instance.
 - Store vou pointer in zx_crtc, so that we do not need to embed the
   pointer in zx_drm_private.
 - Create zx_readl/zx_writel/zx_writel_mask for register access.
 - Define a few macro helpers to ease the register bit setting, like
   SYNC_WIDE, BACK_PORCH and FRONT_PORCH.
 - Define main/aux channel specific register offset and bits in zx_crtc
   to save the use of is_main check
 - Sort include headers alphabetically
 - Removing encoder pointer out of the structure and constify struct
   vou_inf
 - Add log message for error conditions
 - Make the function calls in teardown path asymmetrical
 - A few coding style improvements like defining macro for sub-module
   address and changing code to save indentation level
 - Add a MAINTAINERS entry for ZTE ZX DRM driver

Changes for v2:
 - Change device tree bindings to kill the virtual display-subsystem
   node make VOU the parent node.
