new display LVDS

Hi to everybody,

i coming crazy to add a new lvds to my embedded linux. I have an i.MX6 with kernel versoin 3.0.35 and FS ubuntu 12.02.

It works fine, but now i have to add a new lvds with a resolution as 640 x 480. Its clock frequency is about 25.18 with a maximum of 28.33. I added in ldc.c the new resolution, but with default valued i get a clock frequency of 38 MHz. Searching on google, i found to modifify clock.c file (arch/arm/mach-mx6/clock.c) and set

clk_set_parent(&ldb_di0_clk, &pll5_video_main_clk);

Defautl value is clk_set_parent(&ldb_di0_clk, &pll2_pfd_352M);

Chanching it, the clock frequency goes from 38kHz to 33, but not to 25.

Can anyone help me?

Hello Giorgio,

Just as reference I'm adding a link to the other LVDS Clock thread created since these are very similar:
