||
|
|
|
||
|
|
- 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.
