Merge tag 'mmc-updates-for-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc 

Pull MMC updates from Chris Ball:
 "MMC highlights for 3.14:

  Core:
   - Avoid get_cd() on cards marked nonremovable

  Drivers:
   - arasan: New driver for controllers found in e.g. Xilinx Zynq SoC
   - dwmmc: Support Hisilicon K3 SoC controllers
   - esdhc-imx: Support for HS200 mode, DDR modes on MX6, runtime PM
   - sdhci-pci: Support O2Micro/BayHubTech controllers used in laptops
     like Lenovo ThinkPad W540, Dell Latitude E5440, Dell Latitude E6540
   - tegra: Support Tegra124 SoCs"

Device Tree Bindings for the Arasan SDHCI Controller



  The bindings follow the mmc[1], clock[2] and interrupt[3] bindings. Only

  deviations are documented here.



  [1] Documentation/devicetree/bindings/mmc/mmc.txt

  [2] Documentation/devicetree/bindings/clock/clock-bindings.txt

  [3] Documentation/devicetree/bindings/interrupt-controller/interrupts.txt



Required Properties:

  - compatible: Compatibility string. Must be 'arasan,sdhci-8.9a'

  - reg: From mmc bindings: Register location and length.

  - clocks: From clock bindings: Handles to clock inputs.

  - clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb"

  - interrupts: Interrupt specifier

  - interrupt-parent: Phandle for the interrupt controller that services

		      interrupts for this device.



Example:

	sdhci@e0100000 {

		compatible = "arasan,sdhci-8.9a";

		reg = <0xe0100000 0x1000>;

		clock-names = "clk_xin", "clk_ahb";

		clocks = <&clkc 21>, <&clkc 32>;

		interrupt-parent = <&gic>;

		interrupts = <0 24 4>;

	} ;

* Hisilicon specific extensions to the Synopsys Designware Mobile

  Storage Host Controller



Read synopsys-dw-mshc.txt for more details



The Synopsys designware mobile storage host controller is used to interface

a SoC with storage medium such as eMMC or SD/MMC cards. This file documents

differences between the core Synopsys dw mshc controller properties described

by synopsys-dw-mshc.txt and the properties used by the Hisilicon specific

extensions to the Synopsys Designware Mobile Storage Host Controller.



Required Properties:



* compatible: should be one of the following.

  - "hisilicon,hi4511-dw-mshc": for controllers with hi4511 specific extentions.



Example:



	/* for Hi3620 */



	/* SoC portion */

	dwmmc_0: dwmmc0@fcd03000 {

		compatible = "hisilicon,hi4511-dw-mshc";

		reg = <0xfcd03000 0x1000>;

		interrupts = <0 16 4>;

		#address-cells = <1>;

		#size-cells = <0>;

		clocks = <&mmc_clock HI3620_SD_CIUCLK>, <&clock HI3620_DDRC_PER_CLK>;

		clock-names = "ciu", "biu";

	};



	/* Board portion */

	dwmmc0@fcd03000 {

		num-slots = <1>;

		vmmc-supply = <&ldo12>;

		fifo-depth = <0x100>;

		supports-highspeed;

		pinctrl-names = "default";

		pinctrl-0 = <&sd_pmx_pins &sd_cfg_func1 &sd_cfg_func2>;

		slot@0 {

			reg = <0>;

			bus-width = <4>;

			disable-wp;

			cd-gpios = <&gpio10 3 0>;

		};

	};
