AKM AK8963 3-axis electronic compass driver
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should be "ak,ak8963".
|
|
- reg : i2c address of the device.
|
|
- pinctrl-names : The pinctrl configration names of this sensor driver. Should be "ak8963_default".
|
|
- pinctrl-0 : The pinctrl node corresponding to "ak8963_default", should be <&ak8963_default>.
|
|
- interrupt-parent : Parent of interrupt.
|
|
- interrupts : Ecompass interrupt to indicate new data ready.
|
|
- vdd-supply : Analog power supply needed to power up the device.
|
|
- vio-supply : Digital IO power supply needed for IO and I2C.
|
|
- ak,layout : The layout of the ecompass sensor chip. There are 8
|
|
patterns of layout described as below:
|
|
0: Indicate the invalid pattern, The userspace will decide the pattern.
|
|
1: 1st pin is right down
|
|
2: 1st pin is left down
|
|
3: 1st pin is left top
|
|
4: 1st pin is right top
|
|
5: 1st pin is left down (from top view)
|
|
6: 1st pin is left top (from top view)
|
|
7: 1st pin is right top (from top view)
|
|
8: 1st pin is right down (from top view)
|
|
|
|
Optional properites:
|
|
- ak,gpio_rstn : The gpio pin to reset the sensor chip.
|
|
- ak,auto-report : Enable auto-report mode.
|
|
Example:
|
|
akm@c {
|
|
compatible = "ak,ak8963";
|
|
reg = <0x0c>;
|
|
pinctrl-names = "ak8963_default";
|
|
pinctrl-0 = <&ak8963_default>;
|
|
interrupt-parent = <&msm_gpio>;
|
|
interrupts = <69 0x2>;
|
|
vdd-supply = <&pm8916_l17>;
|
|
vio-supply = <&pm8916_l6>;
|
|
ak,layout = <0x0>;
|
|
ak,gpio_rstn = <&msm_gpio 82 0x0>;
|
|
ak,auto-report;
