1*4882a593SmuzhiyunInvensense MPU-3050 Gyroscope device tree bindings
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun  - compatible : should be "invensense,mpu3050"
5*4882a593Smuzhiyun  - reg : the I2C address of the sensor
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunOptional properties:
8*4882a593Smuzhiyun  - interrupts : interrupt mapping for the trigger interrupt from the
9*4882a593Smuzhiyun    internal oscillator. The following IRQ modes are supported:
10*4882a593Smuzhiyun    IRQ_TYPE_EDGE_RISING, IRQ_TYPE_EDGE_FALLING, IRQ_TYPE_LEVEL_HIGH and
11*4882a593Smuzhiyun    IRQ_TYPE_LEVEL_LOW. The driver should detect and configure the hardware
12*4882a593Smuzhiyun    for the desired interrupt type.
13*4882a593Smuzhiyun  - vdd-supply : supply regulator for the main power voltage.
14*4882a593Smuzhiyun  - vlogic-supply : supply regulator for the signal voltage.
15*4882a593Smuzhiyun  - mount-matrix : see iio/mount-matrix.txt
16*4882a593Smuzhiyun
17*4882a593SmuzhiyunOptional subnodes:
18*4882a593Smuzhiyun  - The MPU-3050 will pass through and forward the I2C signals from the
19*4882a593Smuzhiyun    incoming I2C bus, alternatively drive traffic to a slave device (usually
20*4882a593Smuzhiyun    an accelerometer) on its own initiative. Therefore is supports a subnode
21*4882a593Smuzhiyun    i2c gate node. For details see: i2c/i2c-gate.txt
