dt-bindings: mmc: ti,da830-mmc: convert to DT schema 



Convert TI Highspeed MMC host controller binding to YAML format. Define
'clocks' and 'interrupts' properties to resolve errors identified by
'dt_check' and 'dtb_check'.

* TI Highspeed MMC host controller for DaVinci



The Highspeed MMC Host Controller on TI DaVinci family

provides an interface for MMC, SD and SDIO types of memory cards.



This file documents the properties used by the davinci_mmc driver.



Required properties:

- compatible:

 Should be "ti,da830-mmc": for da830, da850, dm365

 Should be "ti,dm355-mmc": for dm355, dm644x



Optional properties:

- bus-width: Number of data lines, can be <1>, <4>, or <8>, default <1>

- max-frequency: Maximum operating clock frequency, default 25MHz.

- 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. These strings correspond

	1:1 with the DMA specifiers listed in dmas.



Example:

mmc0: mmc@1c40000 {

	compatible = "ti,da830-mmc",

	reg = <0x40000 0x1000>;

	interrupts = <16>;

	bus-width = <4>;

	max-frequency = <50000000>;

	dmas = <&edma 16

		&edma 17>;

	dma-names = "rx", "tx";

};
