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
|
- 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>;
|
};
