Subject: [PATCH 8/9] dt-bindings: spi: atmel-quadspi: QuadSPI driver for Microchip SAM9X60
Date: Wed, 30 Jan 2019 15:08:45 +0000	[thread overview]
Message-ID: <20190130150818.24902-9-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20190130150818.24902-1-tudor.ambarus@microchip.com>

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.

Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com>

 - 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

+- 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>.
