Subject: [PATCH v7 3/4] dt-bindings: input: HID: i2c-hid: Introduce bindings for the Goodix GT7375P
Date: Fri, 11 Dec 2020 09:35:25 -0800	[thread overview]
Message-ID: <20201211092956.v7.3.Ibb28033c81d87fcc13a6ba28c6ea7ac154d65f93@changeid> (raw)
In-Reply-To: <20201211173526.1516653-1-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.
