| |
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.
