+* 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>;
+ };
