I2C-controlled MEMS sensor with 20-bit pressure measurement (pascal) and 12-bit temperature measurement driver only exposes basic functionality, see TODO remarks datasheet: http://cache.freescale.com/files/sensors/doc/data_sheet/MPL3115A2.pdf v2: * store 20-bit value in 32-bit buffer element (instead of 24-bit) * zero buffer to prevent kernel data leak to userspace * fix mutex unlock in trigger handler (thanks Andi Shyti) Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Reviewed-by: Andi Shyti <andi@etezian.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

pressure sensor / altimeter.

To compile this driver as a module, choose M here: the module

will be called mpl3115.

sensors: LPS001WP, LPS331AP.

This driver can also be built as a module. If so, these modules
|
|
will be created:
|
|
- st_pressure (core functions for the driver [it is mandatory]);
|
|
- st_pressure_i2c (necessary for the I2C devices [optional*]);
|
|
- st_pressure_spi (necessary for the SPI devices [optional*]);
|
|
|
|
(*) one of these is necessary to do something.
