Subject: [PATCH v3 2/2] drm/msm/dsi: Add phy configuration for QCM2290
Date: Sat, 24 Sep 2022 15:19:00 +0300 [thread overview]
Message-ID: <20220924121900.222711-3-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20220924121900.222711-1-dmitry.baryshkov@linaro.org>
From: Loic Poulain <loic.poulain@linaro.org>
The QCM2290 SoC a the 14nm (V2.0) single DSI phy. The platform is not
fully compatible with the standard 14nm PHY, so it requires a separate
compatible and config entry.
