[PATCH v2 0/3] dmaengine: qcom: gpi: Add trace event support

[Praveen Talari <praveen.talari@oss.qualcomm.com>]

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.

Changes in v2:
- Reorder TP_STRUCT__entry() fields in gpi_ev_process, gpi_alloc_ring,
  and gpi_ring_info to avoid holes: 8/16-bit fields moved to the end,
  and 64-bit/size_t fields moved before the __string() field (treating
  __string() as 4 bytes of metadata). (Steven Rostedt)
