This series adds tracepoint support to the Qualcomm GPI DMA engine driver, giving structured runtime visibility into GPI DMA behavior without requiring invasive debug patches.
Patch 1 adds the qcom_gpi trace events header, covering command dispatch, IRQ handling, channel/event control state transitions, completion event processing, ring allocation, and TRE contents. Patch 2 wires these tracepoints into the driver alongside the existing dev_dbg() calls. Patch 3 converts the remaining dev_dbg() call sites in the driver to use the new tracepoints instead.
