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>; };
