The imx_3.10.53_1.1.0_ga branch just dropped yesterday, so you'll need to give us a week or so to get things ported for SABRE Lite.
We have a full-featured set for 3.10.31_1.1.0_beta, and it's likely that the device tree is close, but it will take a while to do
regression testing against Freescale's new code base.
This is still very much a work in progress. The LVDS display support is quite different and we haven't yet figured out a way to handle all of our displays in a graceful manner.
If you want to take a look at some preliminary work, you can check in our "boundary-imx_3.10.53_1.1.0_ga-pass1" branch.
