drm/msm/dsi: Don't get DSI index from DT
The DSI host and PHY driver currently expects the DT bindings to provide custom properties "qcom,dsi-host-index" and "qcom,dsi-phy-index" so that the driver can identify which DSI instance it is. The binding isn't acceptable, but the driver still needs to figure out what its instance id. This is now done by storing the mmio starting addresses for each DSI instance in every SoC version in the driver. The driver then identifies the index number by trying to match the stored address with comparing the resource start address we get from DT. We don't have compatible strings for DSI PHY on each SoC, but only the DSI PHY type. We only support one SoC version for each PHY type, so we get away doing the same thing above for the PHY driver. We can revisit this when we support two SoCs with the same DSI PHY. Signed-off-by: Archit Taneja <> Signed-off-by: Rob Clark <>
