- * Synopsys DesignWare I2C
- Required properties :
- - compatible : should be "snps,designware-i2c"
- - reg : Offset and length of the register set for the device
- - interrupts : <IRQ> where IRQ is the interrupt number.
- Recommended properties :
- - clock-frequency : desired I2C bus clock frequency in Hz.
- Optional properties :
- - i2c-sda-hold-time-ns : should contain the SDA hold time in nanoseconds.
- This option is only supported in hardware blocks version 1.11a or newer.
- Example :
- i2c@f0000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "snps,designware-i2c";
- reg = <0xf0000 0x1000>;
- interrupts = <11>;
- clock-frequency = <400000>;
- };
- i2c@1120000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "snps,designware-i2c";
- reg = <0x1120000 0x1000>;
- interrupt-parent = <&ictl>;
- interrupts = <12 1>;
- clock-frequency = <400000>;
- i2c-sda-hold-time-ns = <300>;
- };
