Tony, I've split these patches as follows: Platform data header file changes: git://gitorious.org/linux-omap-dss2/linux.git 3.10/0-dss-headers Board file changes (based on header changes): git://gitorious.org/linux-omap-dss2/linux.git 3.10-lo/board-cleanup DSS panel changes (based on header changes): git://gitorious.org/linux-omap-dss2/linux.git 3.10/1-panel-cleanup Removing unused fields from header files (based on panel changes): git://gitorious.org/linux-omap-dss2/linux.git 3.10/2-late-panel-cleanup The 2-late-panel-cleanup breaks compilation if the arch changes are not merged, so I'll leave that until they have been merged. Do you mind if I add the board-cleanup branch temporarily to omapdss's for-next, to simplify testing? When everything looks ok, I'll remove it and pass the branch to you to be handled through l-o.
