There is lots of agreement around the various shortcomings of the current mux framework for OMAP. All that's missing is someone to step up and do the work. :/ I started a new wiki topic at elinux.org for linux-omap wishlist items: http://elinux.org/OMAP_wishlist here I created a pin-mux section where we could start to keep track of the important features needed in a new mux framework. Adding pointers summaries to some other platforms might be useful here as well. This will help us get a start so when someone is ready to step up and do the work, we'll have a starting point.
