| * 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 |
| - interrupt-parent : the phandle for the interrupt controller. |
| If an interrupt is not specified polling will be used. |
| - 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>; |
| }; |
