From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>
The sam9x60 qspi controller uses 2 clocks, one for the peripheral register
access, the other for the qspi core and phy. Both are mandatory.

v2:
- make "pclk" mandatory even for sama5d2. Unnamed clk will be
supported in the driver.
- drop unneeded example

* Atmel Quad Serial Peripheral Interface (QSPI)
Required properties:
-- compatible: Should be "atmel,sama5d2-qspi".
+- 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
