Yes, I have been out the two past weeks and tried to capture all of
your inputs concerning the HDMI driver.

Today I was able to get access to a wandboard solo and the HDMI image
does look different compared to a wandboard quad board:

- The Linux logo penguins are steady on mx6q, but on mx6solo the
contour lines look like they flicker.
- The kernel log text appears in good white colour with mx6q, but not
so white on mx6solo (tending to green).

Even the U-boot HDMI splash screen is not very steady on mx6solo.

I will try to look at these mx6 solo HDMI issues.
