* 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>;
};
