Subject: [PATCH 0/4] Switch to 1-bit mode SDIO before disabling clocks.

This is a reworking of this code that I promised at the end of
January.

SDIO interrupt in 4-bit mode require the clock to be running.  So we
need to switch to 1-bit mode before turning off the clock.

This series provides infrastructure in mmc-core, and adds the
functionality to omap_hsmmc.

Thanks,
NeilBrown

NeilBrown (4):
      mmc: core: fold mmc_set_bus_width calls into sdio_enable_4bit_bus.
      mmc: core: allow non-blocking form of mmc_claim_host
      mmc: sdio: support switching to 1-bit before turning off clocks
      mmc: omap_hsmmc: switch to 1-bit before stopping clocks.
