From 649a6b8d10aa5cfdb345961ebc8673344e9fcdcf Mon Sep 17 00:00:00 2001 From: Emil Gedenryd Date: Fri, 13 Sep 2024 11:57:02 +0200 Subject: [PATCH] iio: light: opt3001: add missing full-scale range value BugLink: https://bugs.launchpad.net/bugs/2097393 commit 530688e39c644543b71bdd9cb45fdfb458a28eaa upstream. The opt3001 driver uses predetermined full-scale range values to determine what exponent to use for event trigger threshold values. The problem is that one of the values specified in the datasheet is missing from the implementation. This causes larger values to be scaled down to an incorrect exponent, effectively reducing the maximum settable threshold value by a factor of 2. Add missing full-scale range array value.
