-Synopsys DesignWare AMBA 2.0 Synchronous Serial Interface.
-
-Required properties:
-- compatible : "snps,dw-apb-ssi" or "mscc,<soc>-spi", where soc is "ocelot" or
- "jaguar2", or "amazon,alpine-dw-apb-ssi"
-- reg : The register base for the controller. For "mscc,<soc>-spi", a second
- register set is required (named ICPU_CFG:SPI_MST)
-- interrupts : One interrupt, used by the controller.
-- #address-cells : <1>, as required by generic SPI binding.
-- #size-cells : <0>, also as required by generic SPI binding.
-- clocks : phandles for the clocks, see the description of clock-names below.
- The phandle for the "ssi_clk" is required. The phandle for the "pclk" clock
- is optional. If a single clock is specified but no clock-name, it is the
- "ssi_clk" clock. If both clocks are listed, the "ssi_clk" must be first.
-
-Optional properties:
-- clock-names : Contains the names of the clocks:
- "ssi_clk", for the core clock used to generate the external SPI clock.
- "pclk", the interface clock, required for register access. If a clock domain
- used to enable this clock then it should be named "pclk_clkdomain".
-- cs-gpios : Specifies the gpio pins to be used for chipselects.
-- num-cs : The number of chipselects. If omitted, this will default to 4.
-- reg-io-width : The I/O register width (in bytes) implemented by this
- device. Supported values are 2 or 4 (the default).
-
-Child nodes as per the generic SPI binding.
-
-Example:
-
- spi@fff00000 {
- compatible = "snps,dw-apb-ssi";
- reg = <0xfff00000 0x1000>;
- interrupts = <0 154 4>;
