Merge "bindings: Add device-tree bindings for slatecom interface driver"

* Slatecom Interface Driver

slatecom_interface driver creates a slate_com_dev device

node for user space communication. Single user space

client can open device node for communication from hardware.

Hardware will provide access to read/write registers or AHB

memory in the device.

Required properties:

- compatible:	      Must be "qcom,slate-daemon"

Example:

	qcom,slate-daemon {

		compatible = "qcom,slate-daemon";

		};

* Slate Coprocessor Communication Driver

slatecom_spi driver provides a set of apis to perform

register, fifo, ahb read and write operations with slate

over spi interface. It also reads slate status and

sends events to the registered clients.

Required properties:

- compatible:	      Must be "qcom,slate-spi"

Optional properties:

- qcom,irq-gpio: IRQ used by the slate to inturrupt MSM.

Example:

	qcom,slate-spi {

		compatible = "qcom,slate-spi";

			compatible = "qcom,slate-spi";

			interrupt-parent = <&tlmm>;

			/* IRQ from slate */

			qcom,irq-gpio = <&tlmm 104 1>;

		};
