- NXP PCA PCA9564/PCA9665 I2C controller
The PCA9564/PCA9665 serves as an interface between most standard
parallel-bus microcontrollers/microprocessors and the serial I2C-bus
and allows the parallel bus system to communicate bi-directionally
with the I2C-bus.
Required properties :
- reg : Offset and length of the register set for the device
- compatible : one of “nxp,pca9564” or “nxp,pca9665”
Optional properties
- interrupts : the interrupt number
- interrupt-parent : the phandle for the interrupt controller.
If an interrupt is not specified polling will be used. - reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line
is active low, it should be marked GPIO_ACTIVE_LOW. - clock-frequency : I2C bus frequency.
Example:
i2c0: i2c@80000 {
compatible = “nxp,pca9564”;
#address-cells = <1>;
#size-cells = <0>;
reg = <0x80000 0x4>;
reset-gpios = <&gpio1 0 GPIO_ACTIVE_LOW>;
clock-frequency = <100000>;
};
