New Linux patch for AM3517/05 SAU-Module released:

02.07.2012


On-the-fly LCD video mode change using sysfs.
Unipanel driver update. It is able now to change LCD video mode on-the-fly using sysfs files. There is two ways to change video mode: using DSS subsystem, and using unipanel driver.
To change video mode using unipanel driver use the following method:
echo "pixclk,xres/hfp/hbp/hsw,yres/yfp/ybp/ysw" > /sys/devices/platform/omapdss/display0/timings, for example:

# echo "15428,480,272,80,8,10,14,3,4,3" > /sys/module/unipanel/parameters/mode

To change video mode using DSS subsystem use the following method:
echo "pixclk,xres/hfp/hbp/hsw,yres/yfp/ybp/ysw" > /sys/devices/platform/omapdss/display0/timings, for example:

# echo "15428,480/10/8/80,272/4/3/14" > /sys/devices/platform/omapdss/display0/timings

Thus, video mode change using DSS is unified with video mode change for TV encoder, and change using unipanel is unified with mode set through kernel command line, and has ability to set LCD signals polarities.
