+
+The highspeed MMC host controller on Caviums SoCs provides an interface

+as the speed of SD standard 4.0. Only 3.3 Volt is supported.
+
+Required properties:
+ - compatible : should be one of:
+   cavium,octeon-6130-mmc
+   cavium,octeon-7890-mmc
+   cavium,thunder-8190-mmc
+   cavium,thunder-8390-mmc
+   mmc-slot
+ - reg : mmc controller base registers
+ - clocks : phandle
+
+Optional properties:
+ - for cd, bus-width and additional generic mmc parameters
+   please refer to mmc.txt within this directory
+ - cavium,cmd-clk-skew : number of coprocessor clocks before sampling command
+ - cavium,dat-clk-skew : number of coprocessor clocks before sampling data
+
+Deprecated properties:
+- spi-max-frequency : use max-frequency instead
+- cavium,bus-max-width : use bus-width instead
+- power-gpios : use vmmc-supply instead
+- cavium,octeon-6130-mmc-slot : use mmc-slot instead

+Marvell Xenon SDHCI Controller device tree bindings
+This file documents differences between the core mmc properties
+described by mmc.txt and the properties used by the Xenon implementation.
+
+Multiple SDHCs might be put into a single Xenon IP, to save size and cost.
+Each SDHC is independent and owns independent resources, such as register sets,
+clock and PHY.
+Each SDHC should have an independent device tree node.
+
+Required Properties:
+- compatible: should be one of the following
+  - "marvell,armada-3700-sdhci": For controllers on Armada-3700 SoC.
+  Must provide a second register area and marvell,pad-type.
+  - "marvell,armada-ap806-sdhci": For controllers on Armada AP806.
+  - "marvell,armada-cp110-sdhci": For controllers on Armada CP110.
+
+- clocks:
+  Array of clocks required for SDHC.
+  Require at least input clock for Xenon IP core.
+
+- clock-names:
+  Array of names corresponding to clocks property.
+  The input clock for Xenon IP core should be named as "core".
+
+- reg:
+  * For "marvell,armada-3700-sdhci", two register areas.
+    The first one for Xenon IP register. The second one for the Armada 3700 SoC
+    PHY PAD Voltage Control register.
+    Please follow the examples with compatible "marvell,armada-3700-sdhci"
+    in below.
+    Please also check property marvell,pad-type in below.
+
+  * For other compatible strings, one register area for Xenon IP.
+
+Optional Properties:
+- marvell,xenon-sdhc-id:
+  Indicate the corresponding bit index of current SDHC in
+  SDHC System Operation Control Register Bit[7:0].
+  Set/clear the corresponding bit to enable/disable current SDHC.
+  If Xenon IP contains only one SDHC, this property is optional.
+
+- marvell,xenon-phy-type:
+  Xenon support multiple types of PHYs.
+  To select eMMC 5.1 PHY, set:
+  marvell,xenon-phy-type = "emmc 5.1 phy"
+  eMMC 5.1 PHY is the default choice if this property is not provided.
+  To select eMMC 5.0 PHY, set:
+  marvell,xenon-phy-type = "emmc 5.0 phy"
+
+  All those types of PHYs can support eMMC, SD and SDIO.
+  Please note that this property only presents the type of PHY.
+  It doesn't stand for the entire SDHC type or property.
+  For example, "emmc 5.1 phy" doesn't mean that this Xenon SDHC only
+  supports eMMC 5.1.
+
+- marvell,xenon-phy-znr:
+  Set PHY ZNR value.
+  Only available for eMMC PHY.
+  Valid range = [0:0x1F].
+  ZNR is set as 0xF by default if this property is not provided.
+
+- marvell,xenon-phy-zpr:
+  Set PHY ZPR value.
+  Only available for eMMC PHY.
+  Valid range = [0:0x1F].
+  ZPR is set as 0xF by default if this property is not provided.
+
+- marvell,xenon-phy-nr-success-tun:
+  Set the number of required consecutive successful sampling points
+  used to identify a valid sampling window, in tuning process.
+  Valid range = [1:7].
+  Set as 0x4 by default if this property is not provided.
+
+- marvell,xenon-phy-tun-step-divider:
+  Set the divider for calculating TUN_STEP.
+  Set as 64 by default if this property is not provided.
+
+- marvell,xenon-phy-slow-mode:
+  If this property is selected, transfers will bypass PHY.
+  Only available when bus frequency lower than 55MHz in SDR mode.
+  Disabled by default. Please only try this property if timing issues
+  always occur with PHY enabled in eMMC HS SDR, SD SDR12, SD SDR25,
+  SD Default Speed and HS mode and eMMC legacy speed mode.
+
+- marvell,xenon-tun-count:
+  Xenon SDHC SoC usually doesn't provide re-tuning counter in
+  Capabilities Register 3 Bit[11:8].
+  This property provides the re-tuning counter.
+  If this property is not set, default re-tuning counter will
+  be set as 0x9 in driver.
+
+- marvell,pad-type:
+  Type of Armada 3700 SoC PHY PAD Voltage Controller register.
+  Only valid when "marvell,armada-3700-sdhci" is selected.
+  Two types: "sd" and "fixed-1-8v".
+  If "sd" is selected, SoC PHY PAD is set as 3.3V at the beginning and is
+  switched to 1.8V when later in higher speed mode.
+  If "fixed-1-8v" is selected, SoC PHY PAD is fixed 1.8V, such as for eMMC.
+  Please follow the examples with compatible "marvell,armada-3700-sdhci"
+  in below.
+
+Example:
+- For eMMC:
