This is a note to let you know that I've just added the patch titled
iio: admv1013: add mixer_vgate corner cases
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 287d998af24326b009ae0956820a3188501b34a0 Mon Sep 17 00:00:00 2001 From: Antoniu Miclaus antoniu.miclaus@analog.com Date: Mon, 7 Aug 2023 17:38:05 +0300 Subject: iio: admv1013: add mixer_vgate corner cases
Include the corner cases in the computation of the MIXER_VGATE register value.
According to the datasheet: The MIXER_VGATE values follows the VCM such as, that for a 0V to 1.8V VCM, MIXER_VGATE = 23.89 VCM + 81, and for a > 1.8V to 2.6V VCM, MIXER_VGATE = 23.75 VCM + 1.25.
