Subject: [PATCH v9 3/4] dt-bindings: input: HID: i2c-hid: Introduce bindings for the Goodix GT7375P
Date: Fri, 15 Jan 2021 09:06:39 -0800 [thread overview]
Message-ID: <20210115090518.v9.3.Ibb28033c81d87fcc13a6ba28c6ea7ac154d65f93@changeid> (raw)
In-Reply-To: <20210115170641.903392-1-dianders@chromium.org>
This adds new bindings for the Goodix GT7375P touchscreen. While this
touchscreen's communications are based on the generic "i2c-over-hid"
protocol, it needs special power sequencing and thus gets its own
compatible and bindings.
