  dmaengine: shdma: fix a regression: initialise DMA channels for memcpy
  dmaengine: shdma: Fix up fallout from runtime PM changes.
  Revert "clocksource: sh_cmt: Runtime PM support"
  Revert "clocksource: sh_tmu: Runtime PM support"
  sh: Fix up asm-generic/ptrace.h fallout.
  sh64: Move from P1SEG to CAC_ADDR for consistent sync.
  sh64: asm/pgtable.h needs asm/mmu.h
  sh: asm/tlb.h needs linux/swap.h
  sh: mark DMA slave ID 0 as invalid
  sh: Update shmin to reflect PIO dependency.
  sh: arch/sh/kernel/process_32.c needs linux/prefetch.h.
  sh: add MMCIF runtime PM support on ecovec
  sh: switch ap325rxa to dynamically manage the platform camera
