The DSI PHY/PLL was relying on a global "xo" clock to be found, but the real clock is named "xo_board" in the DT. The standard nowadays is to never use global clock names anymore but require the firmware (DT) to provide every clock binding explicitly with .fw_name. The DSI PLLs have since been converted to this mechanism (specifically 14nm for SDM660) and this transient clock can now be removed.
This issue was originally discovered in: https://lore.kernel.org/linux-arm-msm/386db1a6-a1cd-3c7d-a88e-dc83f8a1be96@s... and prevented the removal of "xo" at that time.
