I tried applying the= m > to v3.15-rc5 but 1/4 doesn't apply cleanly. It is on top of next-20140509. Now that I looked at my branch, I missed one small patch from the serie= s which could cause the issue (removing the memset from edma_of_parse_dt). I'll resend ASAP with that patch included. >=20 > Thanks, > Sekhar >=20 --=20 P=E9ter
