From: Mayuresh Janorkar <mayur@xxxxxx>
This patch would add two APIs for panel-taal:
check_timings and set_timings.
These are required by omapfb in case we wish to set default mode through bootargs.
e.g.: omapfb.mode="lcd:640x480-16" (display device:width X height - bits per pixel)
omapfb_set_def_mode function in omapfb-main.c essentially needs these functions
otherwise it would return -EINVAL and default mode sent through bootargs
would be ignored.
