Subject: [PATCH v2 1/5] dt-bindings: input: Add binding for bma150 sensor
Date: Sat, 2 Feb 2019 16:18:02 +0100 [thread overview]
Message-ID: <20190202151806.9064-2-pawel.mikolaj.chmiel@gmail.com> (raw)
In-Reply-To: <20190202151806.9064-1-pawel.mikolaj.chmiel@gmail.com>
From: Jonathan Bakker <xc-racer2@live.ca>
Add device tree bindings for Bosch BMA150 Accelerometer Sensor
Changes from v1:
- Add properties for all of bma150_cfg
- Correct IRQ type in example

+* Bosch BMA150 Accelerometer Sensor
+
+Also works for the SMB380 and BMA023 accelerometers
+
+Required properties:
+- compatible : Should be "bosch,bma150"
+- reg : The I2C address of the sensor
+
+Optional properties:
+- interrupt-parent : should be the phandle for the interrupt controller
+- interrupts : Interrupt mapping for IRQ. If not present device will be polled
+- any-motion-int : bool for if the any motion interrupt should be enabled
+- hg-int : bool for if the high-G interrupt should be enabled
+- lg-int : bool for if the low-G interrupt should be enabled
+- any-motion-cfg : array of integers for any motion duration and threshold
+- hg-cfg : array of integers for high-G hysterisis, duration, and threshold
+- lg-cfg : array of integers for low-G hysterisis, duration, and threshold
+- range : configuration of range, one of BMA150_RANGE_* as defined in [1]
+- bandwidth : refresh rate of device, one of BMA150_BW_* as defined in [1]
+
+Example:
+
+bma150@38 {
+ compatible = "bosch,bma150";
+ reg = <0x38>;
+ interrupt-parent = <&gph0>;
+ interrupts = <1 IRQ_TYPE_EDGE_RISING>;
+ any-motion-int;
+ hg-int;
+ lg-int;
+ any-motion-cfg = <0 0>;
+ hg-cfg = <0 150 160>;
+ lg-cfg = <0 150 20>;
+ range = <BMA150_RANGE_2G>;
+ bandwidth = <BMA150_BW_50HZ>;
+};
