-* 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>.
