-* 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 at f0020000 {
- compatible = "atmel,sama5d2-qspi";
- reg = <0xf0020000 0x100>, <0xd0000000 0x8000000>;
- reg-names = "qspi_base", "qspi_mmap";
- interrupts = <52 IRQ_TYPE_LEVEL_HIGH 7>;

- clock-names = "pclk";
- #address-cells = <1>;
- #size-cells = <0>;
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_spi0_default>;
