Cadence SPI controller Device Tree Bindings ------------------------------------------- Required properties: - compatible : Should be "cdns,spi-r1p6" or "xlnx,zynq-spi-r1p6". - reg : Physical base address and size of SPI registers map. - interrupts : Property with a value describing the interrupt number. - clock-names : List of input clock names - "ref_clk", "pclk" (See clock bindings for details). - clocks : Clock phandles (see clock bindings for details). Optional properties: - num-cs : Number of chip selects used. If a decoder is used, this will be the number of chip selects after the decoder. - is-decoded-cs : Flag to indicate whether decoder is used or not. Example: spi@e0007000 { compatible = "xlnx,zynq-spi-r1p6"; clock-names = "ref_clk", "pclk"; clocks = <&clkc 26>, <&clkc 35>; interrupt-parent = <&intc>; interrupts = <0 49 4>; num-cs = <4>; is-decoded-cs = <0>; reg = <0xe0007000 0x1000>; } ;
