+TODO
+. check error handling/cleanup paths
+. add drm_plane / overlay support
+. add video decode/encode support (via syslink3 + codec-engine)
+. still some rough edges with flipping.. event back to userspace should
+ really come after VSYNC interrupt
+. where should we do eviction (detatch_pages())? We aren't necessarily
+ accessing the pages via a GART, so maybe we need some other threshold
+ to put a cap on the # of pages that can be pin'd. (It is mostly only
+ of interest in case you have a swap partition/file.. which a lot of
+ these devices do not.. but it doesn't hurt for the driver to do the
+ right thing anyways.)
+ . Use mm_shrinker to trigger unpinning pages. Need to figure out how
+ to handle next issue first (I think?)
+ . Note TTM already has some mm_shrinker stuff.. maybe an argument to
+ move to TTM? Or maybe something that could be factored out in common?
+. GEM/shmem backed pages can have existing mappings (kernel linear map,
+ etc..), which isn't really ideal.
+. 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
+ before CRTC's are re-enabled, to prevent DSS from trying to DMA from a
+ buffer mapped in DMM/TILER before LUT is reloaded.
+. Add debugfs information for DMM/TILER
+
+Userspace:
+. git://github.com/robclark/xf86-video-omap.git
+
+Currently tested on
+. OMAP3530 beagleboard
+. OMAP4430 pandaboard
+. OMAP4460 pandaboard
