This driver is used with the J2, an open-source VHDL reimplementation of SH-2. I've split it out from the main J-Core support patches going upstream through my own linux-sh tree. Changes since the v3 should include everything requested by Mark Brown in previous review (mainly the chipsel changes I failed to make before), plus significant cleanup (removal of unused macros and other cruft) and refactoring to eliminate duplicate code.
