Subject: [PATCH v2] dt-bindings: input: touchscreen: ilitek_ts_i2c: Absorb ili2xxx bindings
Date: Fri, 3 Dec 2021 14:58:26 +0100 [thread overview]
Message-ID: <0c5f06c9d262c1720b40d068b6eefe58ca406601.1638539806.git.geert+renesas@glider.be> (raw)
While Linux uses a different driver, the Ilitek
ILI210x/ILI2117/ILI2120/ILI251x touchscreen controller Device Tree
binding documentation is very similar.
- Drop the fixed reg value, as some controllers use a different
address,
- Make reset-gpios optional, as it is not always wired.
