T20 U-boot DTS file question

I’m looking LCD configuration in u-boot through DTS file.
I cannot figure out what is the exact meaning of
horiz_timing = <0 136 160 24>
vert_timing = < 1 2 21 11 >
What every number refer to ?

Thank you for your attention.

What exact hardware/software version of things are you talking about?

Please note that on Colibri T20 our regular downstream BSP does not even make use of any device tree at all.

I am talking about:
which is compiled by DTC compiler in U-boot V2.3 project
which is included in Linux V2.3 BSP
The hardware is T20 V1.2A.


Have a look at the documentation thereof here.
