1* NXP PCA PCA9564/PCA9665 I2C controller 2 3The PCA9564/PCA9665 serves as an interface between most standard 4parallel-bus microcontrollers/microprocessors and the serial I2C-bus 5and allows the parallel bus system to communicate bi-directionally 6with the I2C-bus. 7 8Required properties : 9 10 - reg : Offset and length of the register set for the device 11 - compatible : one of "nxp,pca9564" or "nxp,pca9665" 12 13Optional properties 14 - interrupts : the interrupt number 15 - reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line 16 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
