Subject[PATCH 8/9] dt-bindings: spi: atmel-quadspi: QuadSPI driver for Microchip SAM9X60
Date
From: Tudor Ambarus <tudor.ambarus@microchip.com>

The sam9x60 qspi controller uses 2 clocks, one for the peripheral register
access, the other for the qspi core and phy. Both are mandatory.

* 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
- interrupts: Should contain the interrupt for the device.
-- clocks: The phandle of the clock needed by the QSPI controller.
+- clocks: - "atmel,sama5d2-qspi": the phandle of the clock needed by the
+ QSPI controller.
+ - "microchip,sam9x60-qspi": should reference the peripheral
+ and system QSPI clocks.
+- clock-names: Only for sam9x60 - should contain two strigs:
+ - "pclk" for the peripheral clock
+ - "qspick" for the system clock
- #address-cells: Should be <1>.
- #size-cells: Should be <0>.
