Peter Meerwald	cc26ad455f	iio: Add Freescale MPL3115A2 pressure / temperature sensor driver ... 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>	2013-11-24 21:07:13 +00:00
