From 76974ef9d1bf397b7bb97892a3b3bc516a1fc2c2 Mon Sep 17 00:00:00 2001 From: Eugen Hristev Date: Mon, 16 Apr 2018 09:54:03 +0300 Subject: [PATCH] iio: adc: select buffer for at91-sama5d2_adc We need to select the buffer code, otherwise we get build errors with undefined functions on the trigger and buffer, if we select just IIO and then AT91_SAMA5D2_ADC from menuconfig This adds a Kconfig 'select' statement like other ADC drivers have it already.
