Both are mandatory. Signed-off-by: Tudor Ambarus Reviewed-by: Boris Brezillon --- v5: no change v4: collect R-b v3: "pclk" was made mandatory in previous patch. Reword clock descriptions. 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 | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/Documentation/devicetree/bindings/spi/atmel-quadspi.txt b/Docu= mentation/devicetree/bindings/spi/atmel-quadspi.txt index 50bd257e6826..7c40ea694352 100644 --- a/Documentation/devicetree/bindings/spi/atmel-quadspi.txt +++ b/Documentation/devicetree/bindings/spi/atmel-quadspi.txt @@ -1,15 +1,19 @@ * Atmel Quad Serial Peripheral Interface (QSPI) =20 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 reg= isters 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. -- clock-names: Should contain "pclk" for the peripheral clock. +- clocks: Should reference the peripheral clock and the QSPI syste= m + clock if available. +- clock-names: Should contain "pclk" for the peripheral clock and "qspi= ck" + for the system clock when available. - #address-cells: Should be <1>. - #size-cells: Should be <0>. =20 --=20 2.9.5
