-Qualcomm Universal Peripheral (QUP) I2C controller
-
-Required properties:
- - compatible: Should be:
- * "qcom,i2c-qup-v1.1.1" for 8660, 8960 and 8064.
- * "qcom,i2c-qup-v2.1.1" for 8974 v1.
- * "qcom,i2c-qup-v2.2.1" for 8974 v2 and later.
- - reg: Should contain QUP register address and length.
- - interrupts: Should contain I2C interrupt.
-
- - clocks: A list of phandles + clock-specifiers, one for each entry in
- clock-names.
- - clock-names: Should contain:
- * "core" for the core clock
- * "iface" for the AHB clock
-
- - #address-cells: Should be <1> Address cells for i2c device address
- - #size-cells: Should be <0> as i2c addresses have no size component
-
-Optional properties:
- - clock-frequency: Should specify the desired i2c bus clock frequency in Hz,
- defaults to 100kHz if omitted.
-
-Child nodes should conform to i2c bus binding.
-
-Example:
-
- i2c@f9924000 {
- compatible = "qcom,i2c-qup-v2.2.1";
- reg = <0xf9924000 0x1000>;
- interrupts = <0 96 0>;
-
- clocks = <&gcc GCC_BLSP1_QUP2_I2C_APPS_CLK>, <&gcc GCC_BLSP1_AHB_CLK>;
- clock-names = "core", "iface";
-
- clock-frequency = <355000>;
-
- #address-cells = <1>;
- #size-cells = <0>;
- };
