I've tested this on my c630, which does have the nv133fhm-n61,
however... the c630 has 2 different LCD panels available, and I do not
have a c630 which has the other panel (anymore). I reached out on IRC
to the person who has it, but have not yet heard back.

I've been running an equivalent patch for a while, so
Tested-by: Caleb Connolly <[email protected]>
The dsi bridge vcc and vcca supplies are also missing, they're powered
from vreg_l2a_1p2 and controlled by pm8998_gpio 9.

Mind submitting an incremental patch?
