hi
Does MX6SX support progressive display?
MX6SX-----(Progressive, 8bits line)------>ADV7391 ------>RGB
is it possible?
ADV7391 supported Digital TV protocol standard.(SMPTE 293M, BTA T-1004, BT.1358, BT.1362)
Hi moowon
yes it supports YCbCr 4:2:2 format and this is described in
sect.37.4.11 ITU-R BT.656 Digital Video Interface (DVI) i.MX6SX Reference Manual

i have a question
For progressive display out, would i add Progressive modedb?
currently, i show modedb used.
static struct fb_videomode adv739x_modedb[] = {
{
/* NTSC Interlaced output */
"BT656-NTSC", 60, 720, 480, 37037,
.left_margin = 19, .right_margin = 3, /* interpreted as field 0 vertical top/bottom */
.upper_margin = 20, .lower_margin = 3, /* interpreted as field 1 vertical top/bottom */
.hsync_len = 276, .vsync_len = 1, /* htotal clocks = hsync_len + xres*2 */
.sync = FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,
.vmode = FB_VMODE_INTERLACED,
.flag = FB_MODE_IS_DETAILED,},
{
/* PAL Interlaced output */
"BT656-PAL", 50, 720, 576, 37037,
.left_margin = 22, .right_margin = 2, /* interpreted as field 0 vertical top/bottom */
.upper_margin = 23, .lower_margin = 2, /* interpreted as field 1 vertical top/bottom */
.hsync_len = 288, .vsync_len = 1, /* htotal clocks = hsync_len + xres*2 */
.sync = FB_SYNC_HOR_HIGH_ACT | FB_SYNC_VERT_HIGH_ACT,
.vmode = FB_VMODE_INTERLACED,
.flag = FB_MODE_IS_DETAILED,},
};
