| Invensense MPU-3050 Gyroscope device tree bindings |
| |
| Required properties: |
| - compatible : should be "invensense,mpu3050" |
| - reg : the I2C address of the sensor |
| |
| Optional properties: |
| - interrupt-parent : should be the phandle for the interrupt controller |
| - interrupts : interrupt mapping for the trigger interrupt from the |
| internal oscillator. The following IRQ modes are supported: |
| IRQ_TYPE_EDGE_RISING, IRQ_TYPE_EDGE_FALLING, IRQ_TYPE_LEVEL_HIGH and |
| IRQ_TYPE_LEVEL_LOW. The driver should detect and configure the hardware |
| for the desired interrupt type. |
| - vdd-supply : supply regulator for the main power voltage. |
| - vlogic-supply : supply regulator for the signal voltage. |
| - mount-matrix : see iio/mount-matrix.txt |
| |
| Optional subnodes: |
| - The MPU-3050 will pass through and forward the I2C signals from the |
| incoming I2C bus, alternatively drive traffic to a slave device (usually |
| an accelerometer) on its own initiative. Therefore is supports a subnode |
| i2c gate node. For details see: i2c/i2c-gate.txt |
| |
| Example: |
| |
| mpu3050@68 { |
| compatible = "invensense,mpu3050"; |
| reg = <0x68>; |
| interrupt-parent = <&foo>; |
| interrupts = <12 IRQ_TYPE_EDGE_FALLING>; |
| vdd-supply = <&bar>; |
| vlogic-supply = <&baz>; |
| |
| /* External I2C interface */ |
| i2c-gate { |
| #address-cells = <1>; |
| #size-cells = <0>; |
| |
| fnord@18 { |
| compatible = "fnord"; |
| reg = <0x18>; |
| interrupt-parent = <&foo>; |
| interrupts = <13 IRQ_TYPE_EDGE_FALLING>; |
| }; |
| }; |
| }; |
