"[PATCH v3 00/09] ARM: shmobile: APMU DT support via SMP Enable method V3" (http://www.spinics.net/lists/linux-sh/msg45229.html). That series will no longer apply, but I've been carrying (and rebasing) it in my local tree for quite a while, as it was related to SYSC cleanup (avoiding your r8a7792_ca15_scu). But unfortunately that depends on the SYSC node always be present in DT.
