1e00ad7efSChris Packham* NXP PCA PCA9564/PCA9665 I2C controller
2e00ad7efSChris Packham
3e00ad7efSChris PackhamThe PCA9564/PCA9665 serves as an interface between most standard
4e00ad7efSChris Packhamparallel-bus microcontrollers/microprocessors and the serial I2C-bus
5e00ad7efSChris Packhamand allows the parallel bus system to communicate bi-directionally
6e00ad7efSChris Packhamwith the I2C-bus.

8e00ad7efSChris PackhamRequired properties :
9e00ad7efSChris Packham
10e00ad7efSChris Packham - reg : Offset and length of the register set for the device
11e00ad7efSChris Packham - compatible : one of "nxp,pca9564" or "nxp,pca9665"
12e00ad7efSChris Packham
13e00ad7efSChris PackhamOptional properties
14e00ad7efSChris Packham - interrupts : the interrupt number
15e00ad7efSChris Packham - reset-gpios : gpio specifier for gpio connected to RESET_N pin. As the line
16e00ad7efSChris Packham   is active low, it should be marked GPIO_ACTIVE_LOW.
17e00ad7efSChris Packham - clock-frequency : I2C bus frequency.
