Subject: [PATCH 3.18 13/16] iio: adc: vf610_adc: Fix VALT selection value for REFSEL bits
Date: Mon, 14 Aug 2017 18:18:22 -0700 [thread overview]
Message-ID: <20170815011733.929667714@linuxfoundation.org> (raw)
In-Reply-To: <20170815011733.115636913@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan-Gabriel Mirea <stefan-gabriel.mirea@nxp.com>
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].
