Although it can help to clean up driver code quite a bit, I'm not sure
it's been done in the right way. So the series can be treated as RFC.
When I was going through DRM drivers for candidates of using
drm_crtc_from_index() helper, I found vblank ha
From: Shawn Guo <shawn@linaro.org>
The vblank is mostly CRTC specific and implemented as part of CRTC
driver. So having vblank hooks in struct drm_crtc_funcs should
generally help to reduce code from client drivers in implementing
drm_driver's vblank callbacks.

With the vblank hooks in struct drm_crtc_funcs, we can directly use the
drm_crtc pointer passed in as parameter and make the functions static.
The functions are moved around to save forward delarations.

With the vblank hooks in struct drm_crtc_funcs, we do not need to
maintain the CRTC specific vblank callbacks with struct
imx_drm_crtc_helper_funcs any more. By moving the stuff that we

With the vblank hooks in struct drm_crtc_funcs, we do not need to
maintain struct rockchip_crtc_funcs and the related registration
functions. Remove them.

Changes for v4:
- Instead of using val, return value directly for zx_vl_get_fmt() and
zx_vl_rsz_get_fmt().
- Fix typo of 'heigth'

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

and only adds VL1 and VL2 into DRM core for now.

Changes for v5:

It adds the TV Encoder driver to support video output in PAL and NTSC
format. The driver uses syscon/regmap interface to configure register
bit sitting in SYSCTRL module for DAC power control.
