Subject: [PATCH 0/1] input: added driver support for the t5400 pressure sensor.
Date: Tue, 20 Nov 2012 22:02:33 +0100	[thread overview]
Message-ID: <1353445355-2517-1-git-send-email-stefan.nilsson@unixphere.com> (raw)

Hi,

This patch is based upon the mainline branch and it enables driver support
for the T5400 digital barometric pressure sensor provided by TDK/EPCOS. This
chip is a low-power, low-noise (<1m altitude resolution) pressure
sensor with support for both I2C- and SPI-interface.

The driver is implemented as a input-poll device with a fixed poll rate at 50 ms
where the raw data is transformed to pressure and temperature values
upon poll execution. Since the chip supports measurement-ready-irq two separate
background threads are implemented for the raw data handling, one threaded
interrupt utilizing the meas-ready irq and another thread utilizing the shared
worker queue.
