-OMAP2+ McSPI device
-
-Required properties:
-- compatible :
-  - "ti,am654-mcspi" for AM654.
-  - "ti,omap2-mcspi" for OMAP2 & OMAP3.
-  - "ti,omap4-mcspi" for OMAP4+.
-- ti,spi-num-cs : Number of chipselect supported  by the instance.
-- ti,hwmods: Name of the hwmod associated to the McSPI
-- ti,pindir-d0-out-d1-in: Select the D0 pin as output and D1 as
-			  input. The default is D0 as input and
-			  D1 as output.
-
-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 for each chip select.
-- dma-names: List of DMA request names. These strings correspond
-	1:1 with the DMA specifiers listed in dmas. The string naming
-	is to be "rxN" and "txN" for RX and TX requests,
-	respectively, where N equals the chip select number.
-
-Examples:
-
-[hwmod populated DMA resources]

-    #address-cells = <1>;
