Merge tag 'mmc-v3.17-1' of git://git.linaro.org/people/ulf.hansson/mmc 

Pull MMC updates from Ulf Hansson:
 "Me and Chris Ball decided to try out using my MMC tree as the primary
  one, to simplify handling of patches.

  This pull does thus contains all the MMC patches for 3.17 rc1, no pull
  from Chris this time.

  Details:

  MMC core:
   - forward compatibility for eMMC
   - fix some blacklisted cards with broken secure discard

  MMC host:
   - mmci: Add support for Qualcomm variant
   - mmci: Fix regression for arm_variant
   - sdhci: Various fixes and cleanups
   - sdhci: Improve external VDD regulator support
   - sdhci: Support for DDR50 1.8V mode for BayTrail
   - sdhci-st: Add driver for ST SDHCI controller
   - sh-mmcif: DMA fixes
   - omap_hsmmc: Add support for SDIO interrupts
   - sdhci-pci: Add support for Intel Quark X1000
   - dw_mmc: Update the reset sequence
   - s3cmci: port DMA code to dmaengine API"

Required properties for a slot (Deprecated - Recommend to use one slot per host):



* gpios: specifies a list of gpios used for command, clock and data bus. The

  first gpio is the command line and the second gpio is the clock line. The

  rest of the gpios (depending on the bus-width property) are the data lines in

  no particular order. The format of the gpio specifier depends on the gpio

  controller.

* Renesas Multi Media Card Interface (MMCIF) Controller



This file documents differences between the core properties in mmc.txt

and the properties used by the MMCIF device.





Required properties:



- compatible: must contain one of the following

	- "renesas,mmcif-r8a7740" for the MMCIF found in r8a7740 SoCs

	- "renesas,mmcif-r8a7790" for the MMCIF found in r8a7790 SoCs

	- "renesas,mmcif-r8a7791" for the MMCIF found in r8a7791 SoCs

	- "renesas,sh-mmcif" for the generic MMCIF



- clocks: reference to the functional clock



- dmas: reference to the DMA channels, one per channel name listed in the

  dma-names property.

- dma-names: must contain "tx" for the transmit DMA channel and "rx" for the

  receive DMA channel.





Example: R8A7790 (R-Car H2) MMCIF0



	mmcif0: mmc@ee200000 {

		compatible = "renesas,mmcif-r8a7790", "renesas,sh-mmcif";

		dmas = <&dmac0 0xd1>, <&dmac0 0xd2>;

		dma-names = "tx", "rx";
