Subject: [PATCH v2 10/10] ARM: dts: at91: sama5d2: Add resistive touch device
Date: Tue, 27 Mar 2018 15:32:43 +0300 [thread overview]
Message-ID: <1522153963-1121-11-git-send-email-eugen.hristev@microchip.com> (raw)
In-Reply-To: <1522153963-1121-1-git-send-email-eugen.hristev@microchip.com>
Add generic resistive touch device which is connected to ADC block
inside the SAMA5D2 SoC
Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com>
