    1 Samsung Sensorhub driver
    2 
    3 Sensorhub is a MCU which manages several sensors and also plays the role
    4 of a virtual sensor device.
    5 
    6 Required properties:
    7 - compatible: "samsung,sensorhub-rinato" or "samsung,sensorhub-thermostat"
    8 - spi-max-frequency: max SPI clock frequency
    9 - interrupts: communication interrupt
   10 - ap-mcu-gpios: [out] ap to sensorhub line - used during communication
   11 - mcu-ap-gpios: [in] sensorhub to ap - used during communication
   12 - mcu-reset-gpios: [out] sensorhub reset
   13 
   14 Example:
   15 
   16         shub_spi: shub {
   17                 compatible = "samsung,sensorhub-rinato";
   18                 spi-max-frequency = <5000000>;
   19                 interrupt-parent = <&gpx0>;
   20                 interrupts = <2 0>;
   21                 ap-mcu-gpios = <&gpx0 0 0>;
   22                 mcu-ap-gpios = <&gpx0 4 0>;
   23                 mcu-reset-gpios = <&gpx0 5 0>;
   24         };
