   2
   3 Required properties:
   4         - compatible:           Should be "cascoda,ca8210"
   5         - reg:                  Controlling chip select
   6         - spi-max-frequency:    Maximum clock speed, should be *less than*
   7                                 4000000
   8         - spi-cpol:             Requires inverted clock polarity
   9         - reset-gpio:           GPIO attached to reset
  10         - irq-gpio:             GPIO attached to IRQ
  11 Optional properties:
  12         - extclock-enable:      Include for the ca8210 to route its 16MHz clock
  13                                 to an output
  14         - extclock-freq:        Frequency in Hz of the external clock
  15         - extclock-gpio:        GPIO of the ca8210 to output the clock on
  16
  17 Example:
  18         ca8210@0 {
  19                 compatible = "cascoda,ca8210";
  20                 reg = <0>;
  21                 spi-max-frequency = <3000000>;
  22                 spi-cpol;
  23                 reset-gpio = <&gpio1 1 GPIO_ACTIVE_HIGH>;
  24                 irq-gpio = <&gpio1 2 GPIO_ACTIVE_HIGH>;
  25                 extclock-enable;
  26                 extclock-freq = 16000000;
  27                 extclock-gpio = 2;
