-Device tree configuration for the I2C busses on the AST24XX, AST25XX, and AST26XX SoCs.
-
-Required Properties:
-- #address-cells : should be 1
-- #size-cells : should be 0
-- reg : address offset and range of bus
-- compatible : should be "aspeed,ast2400-i2c-bus"
- or "aspeed,ast2500-i2c-bus"
- or "aspeed,ast2600-i2c-bus"
-- clocks : root clock of bus, should reference the APB
- clock in the second cell
-- resets : phandle to reset controller with the reset number in
- the second cell
-- interrupts : interrupt number
-
-Optional Properties:
-- bus-frequency : frequency of the bus clock in Hz defaults to 100 kHz when not
- specified
-- multi-master : states that there is another master active on this bus.
-
-Example:
-
-i2c {
- compatible = "simple-bus";
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0x1e78a000 0x1000>;
-
- i2c_ic: interrupt-controller@0 {
- #interrupt-cells = <1>;
- compatible = "aspeed,ast2400-i2c-ic";
- reg = <0x0 0x40>;
- interrupts = <12>;
- interrupt-controller;
- };
-
- i2c0: i2c-bus@40 {
- #address-cells = <1>;
- #size-cells = <0>;
- #interrupt-cells = <1>;
- reg = <0x40 0x40>;
- compatible = "aspeed,ast2400-i2c-bus";
