This patch series converts i.MX and MXS mmc binding to json-schema,
fix some minor issues in original binding doc, such as node name should be 'mmc',
compatible name for i.MX27, reg/interrupts should be required properties etc..
Compared to V1, this patch series adds "unevaluatedProperties: false" for
each binding doc.

-* Freescale Enhanced Secure Digital Host Controller (eSDHC) for i.MX
-
-The Enhanced Secure Digital Host Controller on Freescale i.MX family
-provides an interface for MMC, SD, and SDIO types of memory cards.
-
-This file documents differences between the core properties described
-by mmc.txt and the properties used by the sdhci-esdhc-imx driver.
-
-Required properties:
-- compatible : Should be "fsl,<chip>-esdhc", the supported chips include
- "fsl,imx25-esdhc"
- "fsl,imx35-esdhc"
- "fsl,imx51-esdhc"

- "fsl,imx8mp-usdhc"
- "fsl,imx8qm-usdhc"
- "fsl,imx8qxp-usdhc"
-
-Optional properties:
-- fsl,wp-controller : Indicate to use controller internal write protection
-- fsl,delay-line : Specify the number of delay cells for override mode.
- This is used to set the clock delay for DLL(Delay Line) on override mode
- to select a proper data sampling window in case the clock quality is not good
- due to signal path is too long on the board. Please refer to eSDHC/uSDHC
- chapter, DLL (Delay Line) section in RM for details.
-- voltage-ranges : Specify the voltage range in case there are software
- transparent level shifters on the outputs of the controller. Two cells are
- required, first cell specifies minimum slot voltage (mV), second cell
- specifies maximum slot voltage (mV). Several ranges could be specified.
-- fsl,tuning-start-tap: Specify the start dealy cell point when send first CMD19
- in tuning procedure.
-- fsl,tuning-step: Specify the increasing delay cell steps in tuning procedure.
- The uSDHC use one delay cell as default increasing step to do tuning process.
- This property allows user to change the tuning step to more than one delay
- cells which is useful for some special boards or cards when the default
- tuning step can't find the proper delay window within limited tuning retries.
-- fsl,strobe-dll-delay-target: Specify the strobe dll control slave delay target.
- This delay target programming host controller loopback read clock, and this
- property allows user to change the delay target for the strobe input read clock.
- If not use this property, driver default set the delay target to value 7.
- Only eMMC HS400 mode need to take care of this property.
