1 * NXP PCA PCA9564/PCA9665 I2C controller
2
3 The PCA9564/PCA9665 serves as an interface between most standard
4 parallel-bus microcontrollers/microprocessors and the serial I2C-bus
5 and allows the parallel bus system to communicate bi-directionally
6 with the I2C-bus.
7
8 Required properties :
9
10 - reg : Offset and length of the register set for the device
11 - compatible : one of "nxp,pca9564" or "nxp,pca9665"
12
13 Optional 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
19 Example:
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>;
