Display timings in DT are deprecated and new boards should add the
display with a specific compatible to the simple-panel driver and then
link a panel node to the LVDS channels. Take a look at the i.MX6
Nitrogen DTs for an example on how to do this.
Same comment applies to the next patches as well.
Thanks for the example Lucas. Added G121X1-L03 panel which is now in
linux-next
(https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/gpu/drm/panel?h=next-20151127&id=f8fa17ba812b7df1535f6bb75d7264670f5997a6)
v4 patch now uses simple-panel:
