Cover letter [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
