Allowing to configure the property via device tree allows to export this device specific value to userspace via ext_info. This is useful for e.g. iio-sensor-proxy. This came up when adding proximity support to iio-sensor-proxy [1], [2], it is not meant as a vcnl4000 thing but rather as something useful for other proximity sensors too in the future. I've not converted the vcnl4000 binding docs to yaml but can do so as part of this series in a v2 if the approach makes sense. Changes from v2: - as per review comment by Lars-Peter Clausen https://lore.kernel.org/linux-iio/c787921f-c412-4986-14ea-e31b531d3d5b@metafoo.de/ Switch sysfs name to `nearlevel` - as per review comment by Nishant Malpani https://lore.kernel.org/linux-iio/f5ea512c-d427-94c7-cf5f-f1300cbd4aa3@gmail.com/ Add manufacturer do binding document name - as per review comments by Andy Shevchenko - Drop superfluous blank line - Check return value of device_property_read_u32 for '!= 0' instead of '< 0' Changes from v1: - as per review comments by Jonathan Cameron https://lore.kernel.org/linux-iio/20200221120519.43b72007@archlinux/ Document new sysfs file in Documentation/ABI/testing/sysfs-bus-iio-proximity - convert bindings to yaml - bindings: fix typo in near-level property [1]: https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/merge_requests/298 [2]: https://lore.kernel.org/linux-iio/20200210154153.GA26903@bogon.m.sigxcpu.org/ To: Tomas Novotny , Jonathan Cameron ,Hartmut Knaack ,Lars-Peter Clausen ,Peter Meerwald-Stadler ,"Angus Ainslie (Purism)" ,"Guido Günther" ,Marco Felsch ,Thomas Gleixner ,linux-iio@vger.kernel.org,linux-kernel@vger.kernel.org,devicetree@vger.kernel.org, Andy Shevchenko ,Nishant Malpani Guido Günther (4): dt-bindings: iio: vcnl4000: convert bindings to YAML format dt-bindings: iio: light: vcnl4000: Add near-level iio: vcnl4000: Export near level property for proximity sensor Documentation: ABI: document IIO in_proximity_near_level file .../ABI/testing/sysfs-bus-iio-proximity | 10 ++++ .../bindings/iio/light/vcnl4000.txt | 24 --------- .../bindings/iio/light/vishay,vcnl4000.yaml | 53 +++++++++++++++++++ drivers/iio/light/vcnl4000.c | 25 +++++++++ 4 files changed, 88 insertions(+), 24 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-proximity delete mode 100644 Documentation/devicetree/bindings/iio/light/vcnl4000.txt create mode 100644 Documentation/devicetree/bindings/iio/light/vishay,vcnl4000.yaml -- 2.23.0
