* NXP PCA PCA9564/PCA9665 I2C controller12The PCA9564/PCA9665 serves as an interface between most standard3parallel-bus microcontrollers/microprocessors and the serial I2C-bus4and allows the parallel bus system to communicate bi-directionally5with the I2C-bus.67Required properties :89- reg : Offset and length of the register set for the device10- compatible : one of "nxp,pca9564" or "nxp,pca9665"1112Optional properties13- interrupts : the interrupt number14- reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line15is active low, it should be marked GPIO_ACTIVE_LOW.16- clock-frequency : I2C bus frequency.1718Example:19i2c0: i2c@80000 {20compatible = "nxp,pca9564";21#address-cells = <1>;22#size-cells = <0>;23reg = <0x80000 0x4>;24reset-gpios = <&gpio1 0 GPIO_ACTIVE_LOW>;25clock-frequency = <100000>;26};272829
