From 63fc444967591c3849438aa0f21d5de96a928311 Mon Sep 17 00:00:00 2001 From: Daniel Baluta Date: Thu, 11 Jun 2015 18:49:33 +0300 Subject: iio: ABI: Clarify proximity output value Current description for proximity measurement is ambiguous. While the first part says that proximity is measured by observing reflectivity, the second part incorrectly infers that reported values should behave like a distance. This is because of AS3935 lightning sensor which uses the proximity API, while not being a true proximity sensor. Note this is marked for stable as it accompanies a fix in ABI usage to the sx9500 driver which would otherwise appear to be correct.
