For me, DT boot works fine with 3.19-rc1 as is...

...however, I can confirm that framebuffer is broken:
[ 8.230743] omapfb omapfb: no displays
[ 8.255584] omapfb omapfb: failed to setup omapfb
[ 8.260620] platform omapfb: Driver omapfb requests probe deferral
[ 8.284118] of_get_named_gpiod_flags: parsed 'reset-gpios' property of node
'/ocp/spi@48098000/acx565akm@2' - status (0)
[ 8.284271] acx565akm spi1.2: failed to find video source
[ 8.290069] spi spi1.2: Driver acx565akm requests probe deferral
I bisected it to ef691ff48bc8 (OMAPDSS: DT: Get source endpoint
by matching reg-id). When I revert that, also FB works with 3.19-rc1.
