From 78f16dbda5eee2f9379a6313cd01792160e2ec70 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Fri, 27 Nov 2015 14:52:51 +0100 Subject: [PATCH] iio: adc: mcp3422: Add mcp3421 support The mcp3421 is the single channel variant of the mcp342x family. Support is straight forward, only the channels array has to be added for this chip.
