dt-bindings: mmc: Convert jz4740-mmc doc to YAML
Convert the jz4740-mmc.txt documentation to YAML. The ingenic,jz4770-mmc compatible string was added in the process, with a fallback to ingenic,jz4760-mmc. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Rob Herring <robh@kernel.org>

-* Ingenic XBurst MMC controllers
-
-This file documents the device tree properties used for the MMC controller in
-Ingenic JZ4740/JZ4760/JZ4780/X1000 SoCs. These are in addition to the core MMC
-properties described in mmc.txt.
-
-Required properties:
-- compatible: Should be one of the following:
- - "ingenic,jz4740-mmc" for the JZ4740
- - "ingenic,jz4725b-mmc" for the JZ4725B
- - "ingenic,jz4760-mmc" for the JZ4760
- - "ingenic,jz4780-mmc" for the JZ4780
- - "ingenic,x1000-mmc" for the X1000
-- reg: Should contain the MMC controller registers location and length.
-- interrupts: Should contain the interrupt specifier of the MMC controller.
-- clocks: Clock for the MMC controller.
-
-Optional properties:
-- dmas: List of DMA specifiers with the controller specific format
- as described in the generic DMA client binding. A tx and rx
- specifier is required.
-- dma-names: RX and TX DMA request names.
- Should be "rx" and "tx", in that order.
-
-For additional details on DMA client bindings see ../dma/dma.txt.
-
-Example:
-
-mmc0: mmc@13450000 {
- compatible = "ingenic,jz4780-mmc";
- reg = <0x13450000 0x1000>;
-
- interrupt-parent = <&intc>;
- interrupts = <37>;
-
- clocks = <&cgu JZ4780_CLK_MSC0>;
- clock-names = "mmc";
-
- dmas = <&dma JZ4780_DMA_MSC0_RX 0xffffffff>, <&dma JZ4780_DMA_MSC0_TX 0xffffffff>;
- dma-names = "rx", "tx";
-};
