This patch series adds support for I2CXL-MaxSonar ultrasonic distance sensors with i2c interface of vendor MaxBotix Supported types are: mb1202, mb1212, mb1222, mb1232, mb1242, mb7040, mb7137 Implemented and tested functionality: - reading the distance via in_distance_raw - buffered mode with trigger - make use of irq to announce completion of ranging Changes in v3: Thanks to the review of Julia, Jonathan, Rob and Peter there are some changes: - fix missing mutex_unlock() in mb1232_read_distance() - change file and function names to the tested type mb1232 - list all supported types in {of,i2c}_device_id as well as in Kconfig - reduce former status gpio to pure interrupt for announcement of finished read cycle Changes in v2: Thanks to the review of Andreas and Peter there are a couple of changes: - rename type wildcard mb12x2 to i2cxl in dt binding - split changes in vendor list and dt doc into two patches - merge driver source and Kconfig/Makefile change into one patch - reword dt documentation - use directly __be16 datatype to read directly from i2c - use s16 as return value from mb12x2_read_distance() Andreas Klinger (4): dt-bindings: Add vendor prefix for MaxBotix dt-bindings: maxbotix,mb1232: Add MaxBotix i2c ultrasonic rangers mb1232.c: add distance iio sensor with i2c MAINTAINERS: add maintainer for maxbotix ultrasonic driver .../bindings/iio/proximity/maxbotix,mb1232.txt | 31 +++ .../devicetree/bindings/vendor-prefixes.txt | 1 + MAINTAINERS | 7 + drivers/iio/proximity/Kconfig | 12 + drivers/iio/proximity/Makefile | 1 + drivers/iio/proximity/mb1232.c | 274 +++++++++++++++++++++ 6 files changed, 326 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/proximity/maxbotix,mb1232.txt create mode 100644 drivers/iio/proximity/mb1232.c -- 2.11.0
