[PATCH 4/8] mmc: tmio: Keep host active while SDIO irq is enabled

The host must be kept active to be able to serve with SDIO irqs. We prevent it from being put into in-active while the SDIO irq is enabled by simply adding balanced calls to pm_runtime_get|put. Cc: Guennadi Liakhovetski Signed-off-by: Ulf Hansson --- drivers/mmc/host/tmio_mmc.h |1 + dr

[PATCH 7/8] mmc: tmio: Restructure .set_ios and adapt probe sequence to it

An internal power state machine has earlier been used to keep probe and .set_ios in sync. Moreover it was used to handle the specific scenario of using MMC_CLKGATE. A dependency to MMC_CLKGATE existed to handle runtime PM properly, which we moves away from here. By removing the state machine and i
