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.
