This is a note to let you know that I've just added the patch titled iio: adc: vf610_adc: Fix VALT selection value for REFSEL bits to the 4.12-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: iio-adc-vf610_adc-fix-valt-selection-value-for-refsel-bits.patch and it can be found in the queue-4.12 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From d466d3c1217406b14b834335b5b4b33c0d45bd09 Mon Sep 17 00:00:00 2001 From: Stefan-Gabriel Mirea <stefan-gabriel.mirea@xxxxxxx> Date: Thu, 6 Jul 2017 10:06:41 +0100 Subject: iio: adc: vf610_adc: Fix VALT selection value for REFSEL bits From: Stefan-Gabriel Mirea <stefan-gabriel.mirea@xxxxxxx> commit d466d3c1217406b14b834335b5b4b33c0d45bd09 upstream. In order to select the alternate voltage reference pair (VALTH/VALTL), the right value for the REFSEL field in the ADCx_CFG register is "01", leading to 0x800 as register mask. See section 8.2.6.4 in the reference manual[1].
