From eda1b3d42fad388bf285e8d7b45009b61b0e6f6e Mon Sep 17 00:00:00 2001 From: Stefan-Gabriel Mirea Date: Thu, 6 Jul 2017 10:06:41 +0100 Subject: [PATCH] iio: adc: vf610_adc: Fix VALT selection value for REFSEL bits 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].
