This is a note to let you know that I've just added the patch titled
iio: light: opt3001: add missing full-scale range value
to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.
From 530688e39c644543b71bdd9cb45fdfb458a28eaa Mon Sep 17 00:00:00 2001 From: Emil Gedenryd emil.gedenryd@axis.com Date: Fri, 13 Sep 2024 11:57:02 +0200 Subject: iio: light: opt3001: add missing full-scale range value
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.
