This patchset adds support for parallax PING))) and LaserPING sensors as iio driver. The driver is derived from srf04 but the device is using only one GPIO for both triggering and the echo. Only patch 3/4 is sent out this time because the others remain unchanged. Changes in v4: Thanks to Julia for reporting a bug: - fix mutex handling in ping_read() Changes in v3: Thanks to Jonathan who found another bug there are two small changes: - fix inconsistent use of devm_request_irq() and free_irq() - hold mutex until free_irq() is called Changes in v2: Thanks to the reviews of Jonathan, Rob and Michel there are some improvements: - optimize use of macros with to_platform_device() and of_device_get_match_data() - change spacing and typos - simplify ascii art timing diagram - merge patch for driver and corresponding Kconfig and Makefile Andreas Klinger (4): dt-bindings: add vendor prefix parallax dt-bindings: add parallax ping sensors iio: ping: add parallax ping sensors MAINTAINERS: add maintainer for ping iio sensors .../bindings/iio/proximity/parallax-ping.yaml | 51 ++++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 7 + drivers/iio/proximity/Kconfig | 15 + drivers/iio/proximity/Makefile | 1 + drivers/iio/proximity/ping.c | 335 +++++++++++++++++++++ 6 files changed, 411 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/proximity/parallax-ping.yaml create mode 100644 drivers/iio/proximity/ping.c -- 2.11.0
