This preliminary patch series adds support for a new ST LPS22HB pressure sensor and introduce a few fixes related to st_pressure core and st_sensors triggered buffering. It is not meant to be reviewed for definitive inclusion as it touches too many drivers / devices I cannot test with. Note that as a few minor and more controversial patches (7, 8 and 9) might also be candidate for a seperate series. Patch 2 makes st_pressure sensors compliant with ABI and fixes a few missing sampling gains. Scale / offset computation is modified to address all gains currently possible. It impacts LPS331AP, LPS001WP and LPS25H sensors. Please please please ! If anyone owning one of these could run some tests, I'd be glad to get some feedback since I have none of them. Patch 4 is a rework of the way st_sensors samples are stored in memory to comply with IIO expected alignment contraints (some st_pressure samples are 24 bits long). It is heavily based upon Linux Walleij' approach where each channel is captured individually. See http://www.spinics.net/lists/linux-iio/msg24028.html and http://www.spinics.net/lists/linux-iio/msg23598.html threads for more infos. This patch impacts all st_sensors. Please please please ! If anyone owning one of these could run some tests... Patch 5 enforces 32 bits storage alignment for 24 bits long st_pressure sampling channels. Patch 6 enables triggered buffering for st_pressure temperature channels. We need temperature samples to control on-board device temperature (noise and drift removal). Both patches impact st_pressure sensors mentionned above. Please please please ! If anyone owning one of these could run some tests... Regards, gregor.
