Hey all,

I am trying to test Jagan's patch series [1] to add support for the
samsung dsim bridge which is used on the imx8mm to output DSI video.
The DSIM gets the video from the mxsfb, and in my case, the DSI is
sent to the adv7535 for connecting to HDMI.

I had to add some extra patches on top of Jagan's imx8mm-dsi-v3 to get
HDMI output functional on a imx8mm-evk via ADV7535:

Does it work on your board?

I'll give them a try tonight.  I managed to get a hold of an adv7535
user manual, and there are some items that it appears NXP did in their
downstream kernel that never got pushed upstream. Based on my review
of some of the changes, some of the NXP changes seem reasonable to me.
If/when I can get it working, I'll try to report back some of my
findings and push driver changes to the adv7535 as I find them.
