 - gpio-sck: GPIO spec for the SCK line to use

 - gpio-miso: GPIO spec for the MISO line to use

 - gpio-mosi: GPIO spec for the MOSI line to use

 - cs-gpios: GPIOs to use for chipselect lines

 - num-chipselects: number of chipselect lines

 - cs-gpios: GPIOs to use for chipselect lines.

             Not needed if num-chipselects = <0>.

 - num-chipselects: Number of chipselect lines. Should be <0> if a single device

                    with no chip select is connected.

Example:

IMG Synchronous Peripheral Flash Interface (SPFI) controller

Required properties:

- compatible: Must be "img,spfi".

- reg: Must contain the base address and length of the SPFI registers.

- interrupts: Must contain the SPFI interrupt.

- clocks: Must contain an entry for each entry in clock-names.

  See ../clock/clock-bindings.txt for details.

- clock-names: Must include the following entries:

  - spfi: SPI operating clock

  - sys: SPI system interface clock

- dmas: Must contain an entry for each entry in dma-names.

  See ../dma/dma.txt for details.

- dma-names: Must include the following entries:

  - rx

  - tx

- #address-cells: Must be 1.

- #size-cells: Must be 0.

Optional properties:

- img,supports-quad-mode: Should be set if the interface supports quad mode

  SPI transfers.

Example:

spi@18100f00 {

	compatible = "img,spfi";

	reg = <0x18100f00 0x100>;

	interrupts = <GIC_SHARED 22 IRQ_TYPE_LEVEL_HIGH>;

	clocks = <&spi_clk>, <&system_clk>;

	clock-names = "spfi", "sys";

	dmas = <&mdc 9 0xffffffff 0>, <&mdc 10 0xffffffff 0>;

	dma-names = "rx", "tx";

	#address-cells = <1>;

	#size-cells = <0>;

};

Amlogic Meson SPI controllers

* SPIFC (SPI Flash Controller)

The Meson SPIFC is a controller optimized for communication with SPI

NOR memories, without DMA support and a 64-byte unified transmit /

receive buffer.

Required properties:

 - compatible: should be "amlogic,meson6-spifc"

 - reg: physical base address and length of the controller registers

 - clocks: phandle of the input clock for the baud rate generator

 - #address-cells: should be 1

 - #size-cells: should be 0

	spi@c1108c80 {

		compatible = "amlogic,meson6-spifc";

		reg = <0xc1108c80 0x80>;

		clocks = <&clk81>;

		#address-cells = <1>;

		#size-cells = <0>;

	};

	  GPIO operations, you should be able to leverage that for better

	  speed with a custom version of this driver; see the source code.
