-by mmc.txt and the properties used by the sdhci-esdhc driver.
-
-Required properties:
- - compatible : should be "fsl,esdhc", or "fsl,<chip>-esdhc".
- Possible compatibles for PowerPC:
- "fsl,mpc8536-esdhc"

- "fsl,p4080-esdhc"

- Possible compatibles for ARM:
- "fsl,ls1012a-esdhc"

- "fsl,ls1088a-esdhc"
- "fsl,ls1043a-esdhc"
- "fsl,ls1046a-esdhc"
- "fsl,ls2080a-esdhc"
- - clock-frequency : specifies eSDHC base clock frequency.

-Optional properties:
- - sdhci,wp-inverted : specifies that eSDHC controller reports
- inverted write-protect state; New devices should use the generic

- - sdhci,1-bit-only : specifies that a controller can only handle
- 1-bit data transfers. New devices should use the generic
- "bus-width = <1>" property.
- - sdhci,auto-cmd12: specifies that a controller can only handle auto
- CMD12.
- - voltage-ranges : two cells are required, first cell specifies minimum
- slot voltage (mV), second cell specifies maximum slot voltage (mV).
- Several ranges could be specified.
- - little-endian : If the host controller is little-endian mode, specify

-* Spreadtrum SDHCI controller (sdhci-sprd)
-
-The Secure Digital (SD) Host controller on Spreadtrum SoCs provides an interface
-for MMC, SD and SDIO types of cards.
-
-This file documents differences between the core properties in mmc.txt
-and the properties used by the sdhci-sprd driver.
-
-Required properties:
-- compatible: Should contain "sprd,sdhci-r11".
-- reg: physical base address of the controller and length.
-- interrupts: Interrupts used by the SDHCI controller.
-- clocks: Should contain phandle for the clock feeding the SDHCI controller
-- clock-names: Should contain the following:
- "sdio" - SDIO source clock (required)
- "enable" - gate clock which used for enabling/disabling the device (required)
- "2x_enable" - gate clock controlling the device for some special platforms (optional)
-
-Optional properties:
-- assigned-clocks: the same with "sdio" clock
-- assigned-clock-parents: the default parent of "sdio" clock
-- pinctrl-names: should be "default", "state_uhs"
-- pinctrl-0: should contain default/high speed pin control
-- pinctrl-1: should contain uhs mode pin control
-
-PHY DLL delays are used to delay the data valid window, and align the window
-to sampling clock. PHY DLL delays can be configured by following properties,
-and each property contains 4 cells which are used to configure the clock data
-write line delay value, clock read command line delay value, clock read data
-positive edge delay value and clock read data negative edge delay value.
-Each cell's delay value unit is cycle of the PHY clock.
-
-- sprd,phy-delay-legacy: Delay value for legacy timing.
-- sprd,phy-delay-sd-highspeed: Delay value for SD high-speed timing.
-- sprd,phy-delay-sd-uhs-sdr50: Delay value for SD UHS SDR50 timing.
-- sprd,phy-delay-sd-uhs-sdr104: Delay value for SD UHS SDR50 timing.
-- sprd,phy-delay-mmc-highspeed: Delay value for MMC high-speed timing.
-- sprd,phy-delay-mmc-ddr52: Delay value for MMC DDR52 timing.
-- sprd,phy-delay-mmc-hs200: Delay value for MMC HS200 timing.
-- sprd,phy-delay-mmc-hs400: Delay value for MMC HS400 timing.
-- sprd,phy-delay-mmc-hs400es: Delay value for MMC HS400 enhanced strobe timing.
