+When the pm_power_off is called, the gpio is configured as an output,

(0xd00d1e). Perhaps this could be exposed as a define in

3. Maybe device_max_receive() and link_speed_to_max_payload() should be
taken up by the firewire core?
-4. To avoid dropping rx data while still limiting the maximum buffering,
- the size of the AR context must be known. How to expose this to drivers?

. Revisit GEM sync object infrastructure.. TTM has some framework for this
already. Possibly this could be refactored out and made more common?
There should be some way to do this with less wheel-reinvention.
-. Review DSS vs KMS mismatches. The omap_dss_device is sort of part encoder,
- part connector. Which results in a bit of duct tape to fwd calls from
- encoder to connector. Possibly this could be done a bit better.
. Solve PM sequencing on resume. DMM/TILER must be reloaded before any
access is made from any component in the system. Which means on suspend
CRTC's should be disabled, and on resume the LUT should be reprogrammed
