Subject: [PATCH v3 10/10] ARM: dts: at91: sama7g5ek: enable ADC on the board
Date: Wed, 1 Sep 2021 15:30:13 +0300 [thread overview]
Message-ID: <20210901123013.329792-11-eugen.hristev@microchip.com> (raw)
In-Reply-To: <20210901123013.329792-1-eugen.hristev@microchip.com>
The ADC controller on the board is fed by a 2.5V reference voltage.
By default the channels #14 and #15 are dedicated to analog input
(marked AN on the board), on the connectors mikrobus1 and mikrobus2.
