Kernel-4.18.0-80.el8_sensorhub

Samsung Sensorhub driver

Sensorhub is a MCU which manages several sensors and also plays the role
of a virtual sensor device.

Required properties:

• compatible: “samsung,sensorhub-rinato” or “samsung,sensorhub-thermostat”
• spi-max-frequency: max SPI clock frequency
• interrupt-parent: interrupt parent
• interrupts: communication interrupt
• ap-mcu-gpios: [out] ap to sensorhub line - used during communication
• mcu-ap-gpios: [in] sensorhub to ap - used during communication
• mcu-reset-gpios: [out] sensorhub reset

Example:

shub_spi: shub {
    compatible = "samsung,sensorhub-rinato";
    spi-max-frequency = <5000000>;
    interrupt-parent = <&gpx0>;
    interrupts = <2 0>;
    ap-mcu-gpios = <&gpx0 0 0>;
    mcu-ap-gpios = <&gpx0 4 0>;
    mcu-reset-gpios = <&gpx0 5 0>;
};
