Subject: [PATCH v2 09/10] dt-bindings: spi: atmel-quadspi: QuadSPI driver for Microchip SAM9X60
Date: Thu, 31 Jan 2019 16:15:48 +0000	[thread overview]
Message-ID: <20190131161515.21605-10-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20190131161515.21605-1-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>
---
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
 - 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:    Should contain:
+		  - "pclk" for the peripheral clock
+		  - "qspick" for the system clock, when available (sam9x60)
 - #address-cells: Should be <1>.
 - #size-cells:    Should be <0>.
