1*4882a593Smuzhiyun* Asahi Kasei AK8974 magnetometer sensor
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun
5*4882a593Smuzhiyun- compatible:
6*4882a593Smuzhiyun    * "asahi-kasei,ak8974"
7*4882a593Smuzhiyun    * "alps,hscdtd008a"
8*4882a593Smuzhiyun- reg : the I2C address of the magnetometer
9*4882a593Smuzhiyun
10*4882a593SmuzhiyunOptional properties:
11*4882a593Smuzhiyun
12*4882a593Smuzhiyun- avdd-supply: regulator supply for the analog voltage
13*4882a593Smuzhiyun  (see regulator/regulator.txt)
14*4882a593Smuzhiyun- dvdd-supply: regulator supply for the digital voltage
15*4882a593Smuzhiyun  (see regulator/regulator.txt)
16*4882a593Smuzhiyun- interrupts: data ready (DRDY) and interrupt (INT1) lines
17*4882a593Smuzhiyun  from the chip, the DRDY interrupt must be placed first.
18*4882a593Smuzhiyun  The interrupts can be triggered on rising or falling
19*4882a593Smuzhiyun  edges alike.
20*4882a593Smuzhiyun- mount-matrix: an optional 3x3 mounting rotation matrix
21*4882a593Smuzhiyun
