Subject: [PATCH v2 0/7] drm/msm/dsi: Get PHY ref clocks from the DT

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 v2:
- apply to all MSM DSI PHY drivers, not only 10nm

Matthias Kaehlcke (7):
  dt-bindings: msm/dsi: Add ref clock for PHYs
  drm/msm/dsi: 14nm PHY: Get ref clock from the DT
  drm/msm/dsi: 28nm 8960 PHY: Get ref clock from the DT
  arm64: dts: qcom: msm8916: Set 'xo_board' as ref clock of the DSI PHY
  drm/msm/dsi: 28nm PHY: Get ref clock from the DT
  arm64: dts: sdm845: Set 'bi_tcxo' as ref clock of the DSI PHYs
  drm/msm/dsi: 10nm PHY: Get ref clock from the DT
