0001 * NXP PCA PCA9564/PCA9665 I2C controller
0002
0003 The PCA9564/PCA9665 serves as an interface between most standard
0004 parallel-bus microcontrollers/microprocessors and the serial I2C-bus
0005 and allows the parallel bus system to communicate bi-directionally
0006 with the I2C-bus.
0007
0008 Required properties :
0009
0010  - reg : Offset and length of the register set for the device
0011  - compatible : one of "nxp,pca9564" or "nxp,pca9665"
0012
0013 Optional properties
0014  - interrupts : the interrupt number
0015  - reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line
0016    is active low, it should be marked GPIO_ACTIVE_LOW.
0017  - clock-frequency : I2C bus frequency.
0018
0019 Example:
0020         i2c0: i2c@80000 {
0021                 compatible = "nxp,pca9564";
0022                 #address-cells = <1>;
0023                 #size-cells = <0>;
0024                 reg = <0x80000 0x4>;
0025                 reset-gpios = <&gpio1 0 GPIO_ACTIVE_LOW>;
0026                 clock-frequency = <100000>;
0027         };
