Merge branch 'msm-mmc_sdcc' of git://codeaurora.org/quic/kernel/dwalker/linux-msm
* 'msm-mmc_sdcc' of git://codeaurora.org/quic/kernel/dwalker/linux-msm: drivers: mmc: msm_sdcc: Add EMBEDDED_SDIO support mmc: msm_sdcc: Fix issue where clocks could be disabled mid transaction mmc: msm_sdcc: Fix the dma exec function to use the proper delays mmc: msm_sdcc: Don't set host->curr.mrq until after we're sure the busclk timer won't fire mmc: msm_sdcc: Enable busclk idle timer for power savings mmc: msm_sdcc: Don't disable interrupts while suspending mmc: msm_sdcc: Fix issue where we might not end a sucessfull request mmc: msm_sdcc: Featurize busclock power save and disable it by default mmc: msm_sdcc: Fix bug where busclk expiry timer was not properly disabled mmc: msm_sdcc: Reduce command timeouts and improve reliability. mmc: msm_sdcc: Schedule clock disable after probe mmc: msm_sdcc: Wrap readl/writel calls with appropriate clk delays mmc: msm_sdcc: Driver clocking/irq improvements msm: Add 'execute' datamover callback mmc: msm_sdcc: Snoop SDIO_CCCR_ABORT register mmc: msm_sdcc: Clean up clock management and add a 10us delay after enabling clocks
