Since it is the first set of bindings for a gyroscope, the folder for it is also created. Cc: devicetree@vger.kernel.org Cc: Peter Rosin Acked-by: Rob Herring Signed-off-by: Linus Walleij --- ChangeLog v4->v5: - No changes, just reposting. ChangeLog v3->v4: - No changes, just reposting. If we agree on these bindings and since the dependent I2C bindings are merged, this patch should be merge material now I guess. ChangeLog v2->v3: - Augmented device tree bindings to reflect Peter Rosins now merged I2C gate bindings. ChangeLog v1->v2: - Not yet convered to use i2c-gate as I'm waiting for that patch set to stabilize. --- .../bindings/iio/gyroscope/invensense,mpu3050.txt | 46 ++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/gyroscope/invensense,mpu3050.txt -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html diff --git a/Documentation/devicetree/bindings/iio/gyroscope/invensense,mpu3050.txt b/Documentation/devicetree/bindings/iio/gyroscope/invensense,mpu3050.txt new file mode 100644 index 000000000000..b0d3b59966bc --- /dev/null +++ b/Documentation/devicetree/bindings/iio/gyroscope/invensense,mpu3050.txt @@ -0,0 +1,46 @@ +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.
