I took your patchset and fixed it for N950. The main problem was,
that you dropped the fifo size update, which is required for OMAP3
(HW bug). Here is a branch based on recent master branch from
torvalds. I had a quick test with droid4 and dmesg still looked fine,
but I did not have the lm3532 patches in that branch and nothing is
visible without display backlight. Can you check if the branch works
for you on D4?
