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. Signed-off-by: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx> --- v2: - make "pclk" mandatory even for sama5d2. Unnamed clk will be supported in the driver. - drop unneeded example Documentation/devicetree/bindings/spi/atmel-quadspi.txt | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/spi/atmel-quadspi.txt b/Documentation/devicetree/bindings/spi/atmel-quadspi.txt index e9dae6264d89..f949f9197636 100644 --- a/Documentation/devicetree/bindings/spi/atmel-quadspi.txt +++ b/Documentation/devicetree/bindings/spi/atmel-quadspi.txt @@ -1,14 +1,22 @@ * 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>. -- 2.9.5 ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
