1* NXP PCA PCA9564/PCA9665 I2C controller2 3The PCA9564/PCA9665 serves as an interface between most standard4parallel-bus microcontrollers/microprocessors and the serial I2C-bus5and allows the parallel bus system to communicate bi-directionally6with the I2C-bus.7 8Required properties :9 10 - reg : Offset and length of the register set for the device11 - compatible : one of "nxp,pca9564" or "nxp,pca9665"12 13Optional properties14 - interrupts : the interrupt number15 - reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line16 is active low, it should be marked GPIO_ACTIVE_LOW.17 - clock-frequency : I2C bus frequency.18 19Example:20 i2c0: i2c@80000 {21 compatible = "nxp,pca9564";22 #address-cells = <1>;23 #size-cells = <0>;24 reg = <0x80000 0x4>;25 reset-gpios = <&gpio1 0 GPIO_ACTIVE_LOW>;26 clock-frequency = <100000>;27 };28
