Hi Yakir
I'd like you can change your patch title into "drm/rockchip/hdmi", so
when I search patches use "drm/rockchip" can find your patch.
and I have some advices mail inline.
Thanks:-)

The Innosilicon HDMI is a low power HDMI 1.4 transmitter

Changes in v3:
- Use encoder enable/disable function, and remove the encoder DPMS
function
- Keep HDMI PLL power on in standby mode
Changes in v2:
- Using DRM atomic helper functions for connector init (Mark)
- Remove "hdmi->connector.encoder = encoder;" (Mark)

That's seem has some conflicts since the MIPI driver land in mainline.
So you need update it based on the lastest kernel.
Yep, thanks for your reminder, need to update the patch. And by the way
the latest version of this patch have been updated to v5 :)
