something wrong with 1080P on IMX535

I have heared that many people say lvds can't output 1080P, when I try to  check source code ,

If i set the mode is "Spilt",
the code will set the  pixclk is 2*455/7=120M pixclk/s,

check as double rate ,it will be 240M, It will be larger than the width 1080P needed.

when I set to splite mode,fb0 shows

cat mode:

U:1920*1080P-56

but  I can't  measure the clk on the pin...so I can't understand it ,so strangely.

Hi liu,

i.MX53 supports (1866 x 1050 @60 frames per second) as

states sect.47.2.1 MX53 RM. "U:1920*1080P-56" is supported as well.

However for testing better to use OBDS, it is simpler and allows

easily to printf and modify regisers
