[OpenWrt-Devel] [Patch] Support for BMP085 pressure sensor

[Sergey Korolew]

Hello !

Bosch Sensortec is one of most popular pressure sensors for building home weather stations, its cheap and easy to use.
I decided to add two packages for each bus type because device usually have only one barometer and we does no need to waste firmware space for unused bus.
Tested on trunk, ar71xx (ML2030) with kernel 3.10, i2c only (due absent of spi version), but I added patch files for all current kernels.
