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>;
|
|
};
