I'm trying to drive a parallel RGB LCD usign DM365 but I'M NOT ABLE TO
OBTAIN ANY SIGNAL OUT FROM DM365.
I'm using khilman_master_2.6.34-rc1 kernel branch.
I've patched davincifb.c in order to manage output=lcd:format=rgb using
this function:
________________________________________________
static void davincifb_lcd_rgb_config(int on)
{
if (on) {
/* Reset video encoder module */
dispc_reg_out(VENC_VMOD, 0x0);
/* set hsync pulse width */
dispc_reg_out(VENC_HSPLS, dm->osd0->info.var.hsync_len);
/* set vsync pulse width */
dispc_reg_out(VENC_VSPLS, dm->osd0->info.var.vsync_len);
/* set horizontal interval */
dispc_reg_out(VENC_HINT, dm->osd0->info.var.left_margin +
dm->osd0->info.var.right_margin + dm->osd0->
info.var.width);
/* set horizontal data valid start position */
dispc_reg_out(VENC_HSTART, dm->osd0->info.var.left_margin);
/* set Horizontal data valid range */
dispc_reg_out(VENC_HVALID, dm->osd0->info.var.width);
/* set Vertical interval */
dispc_reg_out(VENC_VINT, dm->osd0->info.var.upper_margin +
dm->osd0->info.var.lower_margin + dm->osd0->
info.var.height);
/* set Vertical data valid start position */
dispc_reg_out(VENC_VSTART, dm->osd0->
info.var.upper_margin);
/* set Horizontal data valid range */
dispc_reg_out(VENC_VVALID, dm->osd0->info.var.height);
dispc_reg_out(VENC_DCLKCTL, 0x801);
dispc_reg_out(VENC_DCLKPTN0, 0x03);
dispc_reg_out(VENC_DCLKPTN1, 0x0);
dispc_reg_out(VENC_DCLKPTN2, 0x0);
dispc_reg_out(VENC_DCLKPTN3, 0x0);
dispc_reg_out(VENC_DCLKPTN0A, 0x3);
dispc_reg_out(VENC_DCLKPTN1A, 0x0);
dispc_reg_out(VENC_DCLKPTN2A, 0x0);
dispc_reg_out(VENC_DCLKPTN3A, 0x0);
dispc_reg_out(VENC_OSDCLK1, 3);
/* Enable VCLK */
dispc_reg_out(VENC_VIDCTL, 0x2000);
dispc_reg_out
(VENC_VMOD,(VENC_VMOD_VDMD_RGB666<<VENC_VMOD_VDMD_SHIFT) |VENC_VMOD_ITLCL |
VENC_VMOD_HDMD | VENC_VMOD_VIE | VENC_VMOD_VENC);
#endif
} else {
/* Reset video encoder module */
dispc_reg_out(VENC_VMOD, 0);
}
}
