Subject: [RFC PATCH v3 4/5] arm64: dts: mediatek: mt8173-elm-hana: Mark touchscreens and trackpads as fail
Date:   Tue, 28 Nov 2023 16:42:33 +0800
Message-ID: <20231128084236.157152-5-wenst@chromium.org>
In-Reply-To: <20231128084236.157152-1-wenst@chromium.org>

Precedence: bulk

Instead of having them all available, mark them all as "fail-needs-probe"
and have the implementation try to probe which one is present.
