Will this be ready for 3.14? Depending on that I would handle
omapdss support for the N900 differently. If this code gets merged
into 3.14 I will update the N900 patches [0] accordingly. Otherwise
I would suggest to take the N900 patches as is for 3.14 and I will
take care of adding the omapdss DT support to the panel (and the
N900.dts) separately.
