mmc: core: Remove redundant runtime_idle callback

2014-07-09T09:25:58Z

The runtime PM core handles a runtime_idle callback set to NULL as one returning 0. So, let's just set it to NULL instead. Signed-off-by: Ulf Hansson Acked-by: Jaehoon Chung

mmc: add support for HS400 mode of eMMC5.0

2014-05-12T22:06:06Z

This patch adds HS400 mode support for eMMC5.0 device. HS400 mode is high speed DDR interface timing from HS200. Clock frequency is up to 200MHz and only 8-bit bus width is supported. In addition, tuning process of HS200 is required to synchronize the command response on the CMD line because CMD input timing for HS400 mode is the same as HS200 mode.

mmc: core: Remove unnecessary validations for bus_ops callbacks

2014-02-14T03:58:23Z

Due to the removal of the Kconfig option MMC_UNSAFE_RESUME, several validations of a present bus_ops callback became redundant. Let's remove these. Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

The dev_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the MMC bus code to use the correct field. Cc: Chris Ball Cc: Ulf Hansson Cc: Konstantin Dorfman Cc: Seungwon Jeon Cc: Signed-off-by: Greg Kroah-Hartman

mmc: core: Fixup Oops for SDIO shutdown

2013-07-05T16:51:22Z

Commit "mmc: core: Handle card shutdown from mmc_bus" introduced an Oops in the shutdown sequence for SDIO. The drv pointer, does not exist for SDIO since the probing of the SDIO card from the mmc_bus perspective is expected to fail by returning -ENODEV. This patch adds the proper check for the pointer before calling it.
