Merge tag 'mmc-v3.16-1' of git://git.linaro.org/people/ulf.hansson/mmc into next
Pull MMC update from Ulf Hansson: "These patches are mainly updates for the mmci driver and have been tested in linux-next. Some ARM SoC related patches are also included and those have been acked from the corresponding maintainers to go through my mmc tree. Updates for mmci driver: - Put the device into low power state at system suspend. - Convert to the common mmc DT parser. - Add missing DT bindings needed for ux500. Updates for ARM ux500|u300: - Convert to the common mmc DT bindings. - Remove redundant board file for mmci platform data" * tag 'mmc-v3.16-1' of git://git.linaro.org/people/ulf.hansson/mmc: (22 commits) mmc: mmci: Enforce DMA configuration through DT mmc: mmci: Enforce max frequency configuration through DT mmc: mmci: Enforce mmc capabilities through DT mmc: mmci: Enforce DT for signal direction and feedback clock ARM: ux500: Remove redundant board file for mmci platform data ARM: ux500: Add a vmmc regulator through DT for the poped eMMC for href ARM: ux500: Add the mmc capabilities flags to DT mmc: mmci: Enable MMC_CAP_CMD23 mmc: mmci: Mark the DT bindings for highspeed mode as deprecated ARM: u300: Convert to the common mmc DT bindings for highspeed mode ARM: nomadik: Convert to the common mmc DT bindings for highspeed mode ARM: ux500: Convert to the common mmc DT bindings for highspeed mode ARM: ux500: Add mmci signal directions and feeback clock in DT for href mmc: mmci: Use the common mmc DT parser mmc: mmci: Add DT bindings for feedback clock pin mmc: mmci: Add DT bindings for signal direction mmc: mmci: Update DT documentation mmc: mmci: Convert to devm functions mmc: mmci: Convert to the mmc gpio API mmc: mmci: Put the device into low power state at system suspend ...

by mmc.txt and the properties used by the mmci driver. Using "st" as

the prefix for a property, indicates support by the ST Micro variant.

Required properties:
|

- compatible : contains "arm,pl18x", "arm,primecell".
|

- arm,primecell-periphid : contains the PrimeCell Peripheral ID.
|
||||
- vmmc-supply : phandle to the regulator device tree node, mentioned
|

as the VCC/VDD supply in the eMMC/SD specs.
|
||||
|
||||
Optional properties:
|
||||
- mmc-cap-mmc-highspeed : indicates whether MMC is high speed capable
|
||||
- mmc-cap-sd-highspeed : indicates whether SD is high speed capable
|
||||
- arm,primecell-periphid : contains the PrimeCell Peripheral ID, it overrides

the ID provided by the HW
|

as the VCCQ/VDD_IO supply in the eMMC/SD specs.
|

- st,sig-dir-dat0 : bus signal direction pin used for DAT[0].
|

- st,sig-dir-dat2 : bus signal direction pin used for DAT[2].
|

- st,sig-dir-dat31 : bus signal direction pin used for DAT[3] and DAT[1].
|

- st,sig-dir-dat74 : bus signal direction pin used for DAT[4] to DAT[7].
|

- st,sig-dir-cmd : cmd signal direction pin used for CMD.
|
