Pull MMC updates from Chris Ball:
 "MMC highlights for 3.15:

  Core:
   - CONFIG_MMC_UNSAFE_RESUME=y is now default behavior
   - DT bindings for SDHCI UHS, eMMC HS200, high-speed DDR, at 1.8/1.2V
   - Add GPIO descriptor based slot-gpio card detect API

  Drivers:
   - dw_mmc: Refactor SOCFPGA support as a variant inside dw_mmc-pltfm.c
   - mmci: Support HW busy detection on ux500
   - omap: Support MMC_ERASE
   - omap_hsmmc: Support MMC_PM_KEEP_POWER, MMC_PM_WAKE_SDIO_IRQ, (a)cmd23
   - rtsx: Support pre-req/post-req async
   - sdhci: Add support for Realtek RTS5250 controllers
   - sdhci-acpi: Add support for 80860F16, fix 80860F14/SDIO card detect
   - sdhci-msm: Add new driver for Qualcomm SDHCI chipset support
   - sdhci-pxav3: Add support for Marvell Armada 380 and 385 SoCs"

+PBIAS internal regulator for SD card dual voltage i/o pads on OMAP SoCs.
+
+Required properties:
+- compatible:
+  - "ti,pbias-omap" for OMAP2, OMAP3, OMAP4, OMAP5, DRA7.
+- reg: pbias register offset from syscon base and size of pbias register.
+- syscon : phandle of the system control module
+- regulator-name : should be
+			pbias_mmc_omap2430 for OMAP2430, OMAP3 SoCs
+			pbias_sim_omap3 for OMAP3 SoCs
+			pbias_mmc_omap4 for OMAP4 SoCs
+			pbias_mmc_omap5 for OMAP5 and DRA7 SoC
+
+Optional properties:
+- Any optional property defined in bindings/regulator/regulator.txt
+
+Example:
+
+		pbias_regulator: pbias_regulator {
+			compatible = "ti,pbias-omap";
+			reg = <0 0x4>;
+			syscon = <&omap5_padconf_global>;
+			pbias_mmc_reg: pbias_mmc_omap5 {
+				regulator-name = "pbias_mmc_omap5";
+				regulator-min-microvolt = <1800000>;
+				regulator-max-microvolt = <3000000>;
+			};
