Subject: [PATCH v3 11/11] ARM: dts: at91: sama5d2: Add resistive touch device
Date: Tue, 10 Apr 2018 11:57:57 +0300 [thread overview]
Message-ID: <1523350677-27106-12-git-send-email-eugen.hristev@microchip.com> (raw)
In-Reply-To: <1523350677-27106-1-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>
---
Changes in v3:
- modified compatible and threshold to adapt to changed bindings
Changes in v2:
- now added a generic resistive touchscreen node instead of architecture
specific
