Microchip PIC32 Quad SPI controller

-----------------------------------

Required properties:

- compatible: Should be "microchip,pic32mzda-sqi".

- reg: Address and length of SQI controller register space.

- interrupts: Should contain SQI interrupt.

- clocks: Should contain phandle of two clocks in sequence, one that drives

          clock on SPI bus and other that drives SQI controller.

- clock-names: Should be "spi_ck" and "reg_ck" in order.



Example:

	sqi1: spi@1f8e2000 {

		compatible = "microchip,pic32mzda-sqi";

		reg = <0x1f8e2000 0x200>;

		clocks = <&rootclk REF2CLK>, <&rootclk PB5CLK>;

		clock-names = "spi_ck", "reg_ck";

		interrupts = <169 IRQ_TYPE_LEVEL_HIGH>;

	};
