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

From: NeilBrown
Date: Mon Feb 23 2015 - 21:43:25 EST

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

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.



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.
