The SMI130 is a highly integrated, low power inertial measurement unit (IMU)

that provides precise acceleration and angular rate (gyroscopic) measurement.



To enable driver probing, add the smi130_gyro and smi130_acc node to the platform

device tree as described below.



Required properties:



- compatible: "smi130_gyro", "smi130_acc"

- reg: the I2C address or SPI chip select the device will respond to

- interrupt-parent: phandle to the parent interrupt controller as documented in [interrupts][4]

- interrupts: interrupt mapping for IRQ as documented in [interrupts][4]



Recommended properties for SPI bus usage:

- spi-max-frequency: maximum SPI bus frequency as documented in [SPI][3]



Optional properties:

- smi130_gyro,gpio_irq: MEMS sensor interrupt line to use (default 1)



I2C example (based on Raspberry PI 3):



        &i2c0 {

                status = "ok";

                #address-cells = <0x1>;

                #size-cells = <0x0>;

                smi130_gyro@68 {

                        compatible = "smi130_gyro";

                        reg = <0x68>;

                        interrupt-parent = <&gpio>;

                        interrupts = <26 IRQ_TYPE_EDGE_RISING>;

                };

                smi130_acc@18 {

                        compatible = "smi130_acc";

                        reg = <0x18>;

                        interrupt-parent = <&gpio>;

                        interrupts = <25 IRQ_TYPE_EDGE_RISING>;

                };



SPI example (based on Raspberry PI 3):



        &spi0 {

                status = "ok";

                #address-cells = <0x1>;

                #size-cells = <0x0>;

                smi130_gyro@68 {

                        compatible = "smi130_gyro";

                        reg = <0x68>;

                        interrupt-parent = <&gpio>;

                        interrupts = <26 IRQ_TYPE_EDGE_RISING>;

                };

                smi130_acc@18 {

                        compatible = "smi130_acc";

                        reg = <0x18>;

                        interrupt-parent = <&gpio>;

                        interrupts = <25 IRQ_TYPE_EDGE_RISING>;

                };
