Hi Vũ
seems currently mxsfb.c does not support it so you should add such support himself.
In general NXP has special service for driver customization : https://contact.nxp.com/new-prof-svcs-sw-tech

Hi Vũ
one can try to follow sect.34.4.1.1 Bus Master Operation in Write/Display Modes
i.MX 6ULL Applications Processor Reference Manual
"eLCDIF also provides the capability of interlacing a progressive frame by fetching odd
lines in the first field and then fetching even lines in the second field. This feature can be
used in the DVI mode and can be turned on by setting the INTERLACE_FIELDS bit in
the LCDIF_CTRL1 register."

Hi igor,
I saw only Dotclock is supported on mxsfb.c at: driver/video/fbdev/mxsfb.c
So, how to switch from Dotclock to DVI on imx6ull.
