Initial RFC for new chemical sensor framework, IIO_CONCENTRATION, and IIO_RESISTANCE channel types. Important notes: * Not been tested on real hardware yet but that isn't the main RFC reason and once hardware is in hand it will be verified * Reason the IIO_CONCENTRATION type isn't in percent but has modifiers for ppm and ppb is the scale value for the latter would cause a integer overflow using IIO_VAL_FRACTIONAL Matt Ranostay (4): iio: chemical: Add IIO_CONCENTRATION channel type iio: resistance: add IIO_RESISTANCE channel type devicetree: add SGX Sensortech vendor id iio: chemical: add SGX VZ89x VOC sensor support Documentation/ABI/testing/sysfs-bus-iio | 16 ++ .../devicetree/bindings/i2c/trivial-devices.txt | 1 + .../devicetree/bindings/vendor-prefixes.txt | 1 + drivers/iio/Kconfig | 1 + drivers/iio/Makefile | 1 + drivers/iio/chemical/Makefile | 6 + drivers/iio/chemical/vz89x.c | 237 +++++++++++++++++++++ drivers/iio/industrialio-core.c | 4 + include/uapi/linux/iio/types.h | 4 + 9 files changed, 271 insertions(+) create mode 100644 drivers/iio/chemical/Makefile create mode 100644 drivers/iio/chemical/vz89x.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
