1OMAP2+ McSPI device
2
3Required properties:
4- compatible :
5  - "ti,omap2-mcspi" for OMAP2 & OMAP3.
6  - "ti,omap4-mcspi" for OMAP4+.
7- ti,spi-num-cs : Number of chipselect supported  by the instance.
8- ti,hwmods: Name of the hwmod associated to the McSPI
9- ti,pindir-d0-out-d1-in: Select the D0 pin as output and D1 as
10			  input. The default is D0 as input and
11			  D1 as output.
12
13Optional properties:
14- dmas: List of DMA specifiers with the controller specific format
15	as described in the generic DMA client binding. A tx and rx
16	specifier is required for each chip select.
17- dma-names: List of DMA request names. These strings correspond
18	1:1 with the DMA specifiers listed in dmas. The string naming
19	is to be "rxN" and "txN" for RX and TX requests,
20	respectively, where N equals the chip select number.
