* Atmel Quad Serial Peripheral Interface (QSPI)
Required properties:
- compatible: Should be one of the following:
- "atmel,sama5d2-qspi"
- "microchip,sam9x60-qspi"
- reg: Should contain the locations and lengths of the base registers
and the mapped memory.
- reg-names: Should contain the resource reg names:
- qspi_base: configuration register address space
- qspi_mmap: memory mapped address space
- interrupts: Should contain the interrupt for the device.
- clocks: Should reference the peripheral clock and the QSPI system
clock if available.
- clock-names: Should contain "pclk" for the peripheral clock and "qspick"
for the system clock when available.
- #address-cells: Should be <1>.
- #size-cells: Should be <0>.
Example:
spi@f0020000 {
compatible = "atmel,sama5d2-qspi";
reg = <0xf0020000 0x100>, <0xd0000000 0x8000000>;
reg-names = "qspi_base", "qspi_mmap";
interrupts = <52 IRQ_TYPE_LEVEL_HIGH 7>;
clocks = <&pmc PMC_TYPE_PERIPHERAL 52>;
clock-names = "pclk";
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_spi0_default>;
m25p80@0 {
...
};
};
