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" or "amlogic,meson-gxbb-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>;
|
||
|
|
};
|
||
|
|
|
||
|
|
* 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 and compatible SoCs.
|
||
|
|
"amlogic,meson-axg-spicc" on Amlogic AXG and compatible 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>;
|
||
|
|
};
