[PATCH v2 0/6] DRM driver for verisilicon

[Keith Zhao]

This patch is a drm driver for Starfive Soc JH7110,
I am sending Drm driver part and HDMI driver part.

We used GEM framework for buffer management , and 
for buffer allocation,we use DMA APIs.

the Starfive HDMI servers as interface between a LCD 
Controller and a HDMI bus. A HDMI TX consists of one 
HDMI transmitter controller and one HDMI transmitter PHY.
(Sound support is not include in this patch)

This patchset should be applied after the patchset:

V1:
Changes since v1:
- Further standardize the yaml file.
- Dts naming convention improved.
- Fix the problem of compiling and loading ko files.
- Use drm new api to automatically manage resources.
- Drop struct vs_crtc_funcs&vs_plane_funcs£¬subdivide the plane's help interface
- Reduce the modifiers unused.
- Optimize the hdmi driver code

V2:
Changes since v2:
- fix the error about checking the yaml file.
- match drm driver GEM DMA API.
- Delete the custom crtc property .
- hdmi use drmm_ new api to automatically manage resources.
- update the modifiers comments.
- enabling KASAN, fix the error during removing module
