Subject: [PATCH v2 1/2] arm64: dts: allwinner: a64-amarula-relic: Add GT5663 CTP node
Date: Thu, 18 Apr 2019 14:05:42 +0530 [thread overview]
Message-ID: <20190418083543.11695-1-jagan@amarulasolutions.com> (raw)
Add Goodix GT5663 capacitive touch controller node on
Amarula A64-Relic board.
The CTP connected to board with,
- SDA, SCK from i2c1
- GPIO-LD0 as AVDD28 supply
- PH4 gpio as interrupt pin
- PH8 gpio as reset pin
- X axis is inverted
- Y axis is inverted
