* SPICC (SPI Communication Controller)



The Meson SPICC is generic SPI controller for general purpose Full-Duplex

communications with dedicated 16 words RX/TX PIO FIFOs.



Required properties:

 - compatible: should be "amlogic,meson-gx-spicc" on Amlogic GX SoCs.

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

 - interrupts: The interrupt specifier

 - clock-names: Must contain "core"

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

 - #address-cells: should be 1

 - #size-cells: should be 0



Optional properties:

 - resets: phandle of the internal reset line



See ../spi/spi-bus.txt for more details on SPI bus master and slave devices

required and optional properties.



Example :

	spi@c1108d80 {

		compatible = "amlogic,meson-gx-spicc";

		reg = <0xc1108d80 0x80>;

		interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;

		clock-names = "core";

		clocks = <&clk81>;

		#address-cells = <1>;

		#size-cells = <0>;

	};
