    Depends on whether you want it working via DT or mere platform devices. If 
the second, it's 3.14-rc1. If DT, I don't have a branch, only several patches 
to apply atop of the current 'renesas.git' repo's 'devel' branch that I've 
posted last week (note that only R8A779x is currently supported by these 
patches and NFS boot timeout is still an issue with them).

WBR, Sergei
