This is a note to let you know that I've just added the patch titled
iio: light: veml6030: fix ALS sensor resolution
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 c9e9746f275c45108f2b0633a4855d65d9ae0736 Mon Sep 17 00:00:00 2001 From: Javier Carrasco javier.carrasco.cruz@gmail.com Date: Mon, 23 Sep 2024 00:17:49 +0200 Subject: iio: light: veml6030: fix ALS sensor resolution
The driver still uses the sensor resolution provided in the datasheet until Rev. 1.6, 28-Apr-2022, which was updated with Rev 1.7, 28-Nov-2023. The original ambient light resolution has been updated from 0.0036 lx/ct to 0.0042 lx/ct, which is the value that can be found in the current device datasheet.
Update the default resolution for IT = 100 ms and GAIN = 1/8 from the original 4608 mlux/cnt to the current value from the "Resolution and maximum detection range" table (Application Note 84367, page 5), 5376 mlux/cnt.
