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.
