I2c Slave: Qualcomm Technologies Inc Universal Peripheral.
Required properties:
- compatible: Should be: "qcom,i2c-slave".
- reg: Should contain base register address and length.
- interrupts: Should contain I2C slave interrupt.
- clocks: AHB clock and XO clocks needed by the device.
- pinctrl-names/pinctrl-0/1: The GPIOs assigned to this core. The names
should be "active" and "sleep" for the pin confuguration when core is active
or when entering sleep state.
Optional property:
Child nodes should conform to i2c bus binding.
Example:
i2c_slave{
compatible = "qcom,i2c-slave";
reg = <0x088ca000 0x64>;
interrupt-names = "smbus_alert";
interrupts = <GIC_SPI 535 IRQ_TYPE_LEVEL_HIGH>;
clock-names = "sm_bus_xo_clk", "sm_bus_ahb_clk";
clocks = <&gcc GCC_SM_BUS_XO_CLK>, <&gcc GCC_SM_BUS_AHB_CLK>;
pinctrl-names = "default", "sleep";
pinctrl-0 = <&i2c_slave_sda_active>, <&i2c_slave_scl_active>;
pinctrl-1 = <&i2c_slave_sleep>;
status = "ok";
};
