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>;
};
