  sh: fix Oops in the serial SCI driver
  sh: allow platforms to specify SD-card supported voltages
  mmc: let MFD's provide supported Vdd card voltages to tmio_mmc
  sh: disable SD-card write-protection detection on kfr2r09
  mfd: pass platform flags down to the tmio_mmc driver
  tmio: add a platform flag to disable card write-protection detection
  sh: Add SDHI DMA support to migor
  sh: Add SDHI DMA support to kfr2r09
  sh: Add SDHI DMA support to ms7724se
  sh: Add SDHI DMA support to ecovec
  mmc: add DMA support to tmio_mmc driver, when used on SuperH
  sh: prepare the SDHI MFD driver to pass DMA configuration to tmio_mmc.c
  mmc: prepare tmio_mmc for passing of DMA configuration from the MFD cell
  sh: add DMA slave definitions to sh7724
  sh: add DMA slaves for two SDHI controllers to sh7722
