* 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 - 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>; }; |
