+* Samsung Exynos specific extensions to the Synopsis Designware Mobile
+ Storage Host Controller
+
+The Synopsis 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 Synopsis dw mshc controller properties described
+by synopsis-dw-mshc.txt and the properties used by the Samsung Exynos specific
+extensions to the Synopsis Designware Mobile Storage Host Controller.
+
+Required Properties:
+
+* compatible: should be
+ - "samsung,exynos4210-dw-mshc": for controllers with Samsung Exynos4210
+ specific extensions.
+ - "samsung,exynos4412-dw-mshc": for controllers with Samsung Exynos4412
+ specific extensions.
+ - "samsung,exynos5250-dw-mshc": for controllers with Samsung Exynos5250
+ specific extensions.
+
+* samsung,dw-mshc-ciu-div: Specifies the divider value for the card interface
+ unit (ciu) clock. This property is applicable only for Exynos5 SoC's and
+ ignored for Exynos4 SoC's. The valid range of divider value is 0 to 7.
+
+* samsung,dw-mshc-sdr-timing: Specifies the value of CIU clock phase shift value
+ in transmit mode and CIU clock phase shift value in receive mode for single
+ data rate mode operation. Refer notes below for the order of the cells and the
+ valid values.
+
+* samsung,dw-mshc-ddr-timing: Specifies the value of CUI clock phase shift value
+ in transmit mode and CIU clock phase shift value in receive mode for double
+ data rate mode operation. Refer notes below for the order of the cells and the
+ valid values.
+
+ Notes for the sdr-timing and ddr-timing values:
+
+ The order of the cells should be
+ - First Cell: CIU clock phase shift value for tx mode.
+ - Second Cell: CIU clock phase shift value for rx mode.
+
+ Valid values for SDR and DDR CIU clock timing for Exynos5250:
+ - valid value for tx phase shift and rx phase shift is 0 to 7.
+ - when CIU clock divider value is set to 3, all possible 8 phase shift
+ values can be used.
+ - if CIU clock divider value is 0 (that is divide by 1), both tx and rx
+ phase shift clocks should be 0.
+
+Required properties for a slot:
+
+* 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.
+
+Example:
+
+ The MSHC controller node can be split into two portions, SoC specific and
+ board specific portions as listed below.
+

+These properties are common to multiple MMC host controllers. Any host
+that requires the respective functionality should implement them using
+these definitions.
+
+Interpreted by the OF core:
+- reg: Registers location and length.
+- interrupts: Interrupts used by the MMC controller.
+
+Card detection:
+If no property below is supplied, host native card detect is used.
+Only one of the properties in this section should be supplied:
+ - broken-cd: There is no card detection available; polling must be used.
+ - cd-gpios: Specify GPIOs for card detection, see gpio binding
+ - non-removable: non-removable slot (like eMMC); assume always present.
+
+Optional properties:
+- bus-width: Number of data lines, can be <1>, <4>, or <8>. The default
+ will be <1> if the property is absent.
+- wp-gpios: Specify GPIOs for write protection, see gpio binding
+- cd-inverted: when present, polarity on the CD line is inverted. See the note
+ below for the case, when a GPIO is used for the CD line
+- wp-inverted: when present, polarity on the WP line is inverted. See the note
+ below for the case, when a GPIO is used for the WP line
+- max-frequency: maximum operating clock frequency
+- no-1-8-v: when present, denotes that 1.8v card voltage is not supported on
+ this system, even if the controller claims it is.
+- cap-sd-highspeed: SD high-speed timing is supported
+- cap-mmc-highspeed: MMC high-speed timing is supported
+- cap-power-off-card: powering off the card is safe
+- cap-sdio-irq: enable SDIO IRQ signalling on this interface
+
+*NOTE* on CD and WP polarity. To use common for all SD/MMC host controllers line
+polarity properties, we have to fix the meaning of the "normal" and "inverted"
+line levels. We choose to follow the SDHCI standard, which specifies both those
+lines as "active low." Therefore, using the "cd-inverted" property means, that
+the CD line is active high, i.e. it is high, when a card is inserted. Similar
+logic applies to the "wp-inverted" property.
+
+CD and WP lines can be implemented on the hardware in one of two ways: as GPIOs,
+specified in cd-gpios and wp-gpios properties, or as dedicated pins. Polarity of
+dedicated pins can be specified, using *-inverted properties. GPIO polarity can
+also be specified using the OF_GPIO_ACTIVE_LOW flag. This creates an ambiguity
+in the latter case. We choose to use the XOR logic for GPIO CD and WP lines.
+This means, the two properties are "superimposed," for example leaving the
+OF_GPIO_ACTIVE_LOW flag clear and specifying the respective *-inverted
+property results in a double-inversion and actually means the "normal" line
+polarity is in effect.
+
+Optional SDIO properties:
+- keep-power-in-suspend: Preserves card power during a suspend/resume cycle
+- enable-sdio-wakeup: Enables wake up of host system on SDIO IRQ assertion
+
+Example:
+
+sdhci@ab000000 {
+ compatible = "sdhci";
+ reg = <0xab000000 0x200>;
+ interrupts = <23>;
+ bus-width = <4>;

+* Samsung's SDHCI Controller device tree bindings
+
+Samsung's SDHCI controller is used as a connectivity interface with external
+MMC, SD and eMMC storage mediums. This file documents differences between the
+core mmc properties described by mmc.txt and the properties used by the
+Samsung implmentation of the SDHCI controller.
+
+Note: The mmc core bindings documentation states that if none of the core
+card-detect bindings are used, then the standard sdhci card detect mechanism
+is used. The Samsung's SDHCI controller bindings extends this as listed below.
+
+[A] The property "samsung,cd-pinmux-gpio" can be used as stated in the
+ "Optional Board Specific Properties" section below.
+
+Required SoC Specific Properties:
+- compatible: should be one of the following
+ - "samsung,s3c6410-sdhci": For controllers compatible with s3c6410 sdhci
+ controller.
+ - "samsung,exynos4210-sdhci": For controllers compatible with Exynos4 sdhci
+ controller.
+
+Required Board Specific Properties:
+- Samsung GPIO variant (will be completely replaced by pinctrl):
+ - gpios: Should specify the gpios used for clock, command and data lines. The
+ gpio specifier format depends on the gpio controller.
+- Pinctrl variant (preferred if available):
+ - pinctrl-0: Should specify pin control groups used for this controller.
+ - pinctrl-names: Should contain only one value - "default".
+
+Optional Board Specific Properties:
+- samsung,cd-pinmux-gpio: Specifies the card detect line that is routed
+ through a pinmux to the card-detect pin of the card slot. This property
+ should be used only if none of the mmc core card-detect properties are
+ used. Only for Samsung GPIO variant.
+
+Example:
+ sdhci@12530000 {
+ compatible = "samsung,exynos4210-sdhci";
+ reg = <0x12530000 0x100>;
+ interrupts = <0 75 0>;
+ bus-width = <4>;
+ cd-gpios = <&gpk2 2 2 3 3>;
+
+ /* Samsung GPIO variant */
+ gpios = <&gpk2 0 2 0 3>, /* clock line */
+ <&gpk2 1 2 0 3>, /* command line */
+ <&gpk2 3 2 3 3>, /* data line 0 */
+ <&gpk2 4 2 3 3>, /* data line 1 */
+ <&gpk2 5 2 3 3>, /* data line 2 */
+ <&gpk2 6 2 3 3>; /* data line 3 */

+* Synopsis Designware Mobile Storage Host Controller
+
+The Synopsis 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 mmc properties described by mmc.txt and the
+properties used by the Synopsis Designware Mobile Storage Host Controller.
+
+Required Properties:
+
+* compatible: should be
+ - snps,dw-mshc: for controllers compliant with synopsis dw-mshc.
+* #address-cells: should be 1.
+* #size-cells: should be 0.
+
+# Slots: The slot specific information are contained within child-nodes with
+ each child-node representing a supported slot. There should be atleast one
+ child node representing a card slot. The name of the child node representing
+ the slot is recommended to be slot@n where n is the unique number of the slot
+ connnected to the controller. The following are optional properties which
+ can be included in the slot child node.
+
+ * reg: specifies the physical slot number. The valid values of this
+ property is 0 to (num-slots -1), where num-slots is the value
+ specified by the num-slots property.
+
+ * bus-width: as documented in mmc core bindings.
+
+ * wp-gpios: specifies the write protect gpio line. The format of the
+ gpio specifier depends on the gpio controller. If a GPIO is not used
+ for write-protect, this property is optional.
+
+ * disable-wp: If the wp-gpios property isn't present then (by default)
+ we'd assume that the write protect is hooked up directly to the
+ controller's special purpose write protect line (accessible via
+ the WRTPRT register). However, it's possible that we simply don't
+ want write protect. In that case specify 'disable-wp'.
+ NOTE: This property is not required for slots known to always
+ connect to eMMC or SDIO cards.
+
+Optional properties:
+
+* num-slots: specifies the number of slots supported by the controller.
+ The number of physical slots actually used could be equal or less than the
+ value specified by num-slots. If this property is not specified, the value
+ of num-slot property is assumed to be 1.
+
+* fifo-depth: The maximum size of the tx/rx fifo's. If this property is not
+ specified, the default value of the fifo size is determined from the
+ controller registers.
+
+* card-detect-delay: Delay in milli-seconds before detecting card after card
+ insert event. The default value is 0.
+
+* supports-highspeed: Enables support for high speed cards (upto 50MHz)
+
+* broken-cd: as documented in mmc core bindings.
+
+Aliases:
+
+- All the MSHC controller nodes should be represented in the aliases node using
+ the following format 'mshc{n}' where n is a unique number for the alias.
+
+Example:
+
+The MSHC controller node can be split into two portions, SoC specific and
+board specific portions as listed below.
+
+ dwmmc0@12200000 {
+ compatible = "snps,dw-mshc";

+* Toshiba Mobile IO SD/MMC controller
+
+The tmio-mmc driver doesn't probe its devices actively, instead its binding to
+devices is managed by either MFD drivers or by the sh_mobile_sdhi platform
+driver. Those drivers supply the tmio-mmc driver with platform data, that either
+describe hardware capabilities, known to them, or are obtained by them from
+their own platform data or from their DT information. In the latter case all
+compulsory and any optional properties, common to all SD/MMC drivers, as
+described in mmc.txt, can be used. Additionally the following tmio_mmc-specific
+optional bindings can be used.
+
+Optional properties:
+- toshiba,mmc-wrprotect-disable: write-protect detection is unavailable
+
+When used with Renesas SDHI hardware, the following compatibility strings
+configure various model-specific properties:
+
+"renesas,sh7372-sdhi": (default) compatible with SH7372
+"renesas,r8a7740-sdhi": compatible with R8A7740: certain MMC/SD commands have to
+ wait for the interface to become idle.
