Subject: [PATCH v4 0/8] 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 v4:
- always use parent rate for 28nm and 28nm 8960 PHYs

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

Matthias Kaehlcke (8):
  dt-bindings: msm/dsi: Add ref clock for PHYs
  drm/msm/dsi: 28nm 8960 PHY: Get ref clock from the DT
  drm/msm/dsi: 28nm PHY: Get ref clock from the DT
  drm/msm/dsi: 14nm PHY: Get ref clock from the DT
  drm/msm/dsi: 10nm PHY: Get ref clock from the DT
  arm64: dts: qcom: msm8916: Set 'xo_board' as ref clock of the DSI PHY
  arm64: dts: sdm845: Set 'bi_tcxo' as ref clock of the DSI PHYs
  ARM: dts: qcom-apq8064: Set 'xo_board' as ref clock of the DSI PHY
