Yes, I think that would be good. Depending on the complexity of the patch, you can do it in multiple ways: a) one patch to all the dts files, which also removes the legacy_init_wl12xx() infrastructure b) one patch to add the .dts changes, a second patch to remove the code from pdata-quirks.c and a third to remove the functionality in the driver c) one patch per board. I'm fine with any of these, but the omap maintainers might have a preference.
