Subject: [PATCH v3 0/8] drm/msm/dsi: Get PHY ref clocks from the DT
Date: Fri, 30 Nov 2018 16:52:46 -0800 [thread overview]
Message-ID: <20181201005254.139908-1-mka@chromium.org> (raw)
The MSM DSI PHY drivers currently hardcode the name and the rate of
the PHY ref clock. Get the ref clock from the device tree instead.
Note: testing of this series was limited to SDM845 and the 10nm PHY
Major changes in v3:
- keep supporting DTs without ref clock for the 28nm and the 28nm
8960 PHYs
- added patch to add ref clock to qcom-apq8064.dtsi
Major changes in v2:
- apply to all MSM DSI PHY drivers, not only 10nm
