Pressure Switch
From OMAPpedia
Welcome to the Pressure Sensor webpage.
[edit] Introduction
This webpage describes the Pressure Sensor software development effort, mainly its current status and features planned in the road map.
At present, Pressure sensor is supported only on OMAP4 platforms which uses the BMP085 sensor. It can report Pressure in degree Pascals.
[edit] List of Features Supported
- On OMAP4
- Pressure reporting through sysfs entry.
- Configuration: Allows read and update of configuration parameters via sysfs
[edit] Design
The figure explains the archetural overview of the driver. The sensor interacts with the OMAP using the I2C bus. It reports the sensor values Pressure in this case through sysfs entries.
The driver registers itself using the standard misc device interface.
[edit] Feature Status Summary
Here is the summary of completed, ongoing and planned features in the Pressure sensor driver.

[edit] Upstreaming Sensors - Points for discussion
There was resistance to seeing the driver for the input device. Also it does not justify being a hwmon. So misc device is suggested.
