This patch series adds IIO driver support for srf08 ultrasonic ranger devices. The first patch add a trivial device tree binding for the device together with a new vendor devantech. The second patch is the IIO driver which in turn is using I2C to talk to the device. The third patch documents the added userspace ABI Documentation about the sensor can be found here: http://www.robot-electronics.co.uk/htm/srf08tech.html Changes in v3: Thanks to the reviews of Jonathan, Rob and Lars. Some changes to the driver were made: * Patch 2: "iio: distance: srf08: add IIO driver for us ranger" - defaults values for sensitivity (gain) and max. range are set in probe() - while waiting for ultrasonic echo first wait as long as the physically measurement need as a function of the max. range and then wait in smaller steps until the response can be read. - attributes are now called sensor_sensitivity instead of gain and sensor_max_range instead of range_mm - device-name is now "srf08" - config menu is now calles "Proximity and distance sensors" instead of a separate menu * Patch 3: "iio: distance: srf08: add driver ABI documentation" - newly created to document the driver specific interfaces Changes in v2: Lots of updates thanks to Peters really fast review within 30 minutes after first submission of the driver. * Patch 2: "iio: distance: srf08: add IIO driver for us ranger" - alphabetic order in Makefile - use of u8 while accessing registers - avoid endianness problems with 16 bit values - missing return value checks - some explaining documentation added Andreas Klinger (3): iio: distance: srf08: add trivial DT binding iio: distance: srf08: add IIO driver for us ranger iio: distance: srf08: add driver ABI documentation .../ABI/testing/sysfs-bus-iio-distance-srf08 | 27 ++ .../devicetree/bindings/i2c/trivial-devices.txt | 1 + .../devicetree/bindings/vendor-prefixes.txt | 1 + drivers/iio/proximity/Kconfig | 13 +- drivers/iio/proximity/Makefile | 1 + drivers/iio/proximity/srf08.c | 405 +++++++++++++++++++++ 6 files changed, 447 insertions(+), 1 deletion(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-distance-srf08 create mode 100644 drivers/iio/proximity/srf08.c -- 2.1.4 -- -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
