Subject: [PATCH v2 0/4] add MaxBotix I2CXL ultrasonic iio driver

This patch series adds support for I2CXL-MaxSonar ultrasonic distance
sensors of family mb12x2 using the i2c interface of vendor MaxBotix
    
Implemented and tested functionality:
- reading the distance via in_distance_raw
- buffered mode with trigger
- make use of status gpio to announce completion of ranging


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,i2cxl: Add MaxBotix i2c ultrasonic rangers
  mb12x2.c: add distance iio sensor with i2c
  MAINTAINERS: add maintainer for maxbotix ultrasonic driver
