[PATCH 0/2] Add trace events for Qualcomm GENI SPI drivers

[Praveen Talari]

Add tracepoints to the Qualcomm GENI (Generic Interface) SPI driver.
These trace events enable runtime debugging and performance analysis
of SPI operations.

The trace events capture SPI clock configuration, FIFO parameters,
transfer details, interrupt status, and actual transmitted/received
data in hexadecimal format.

Usage examples:

Enable all SPI traces:
  echo 1 > /sys/kernel/debug/tracing/events/qcom_geni_spi/enable
  cat /sys/kernel/debug/tracing/trace_pipe

Example trace output:

71.364028: geni_spi_fifo_params: 888000.spi: cs=0 mode=0x00000020
   mode_changed=0x00000020 cs_changed=0
71.364054: geni_spi_clk_cfg: 888000.spi: req_hz=10000000
   sclk_hz=100000000 clk_idx=5 clk_div=10 bpw=8
71.364095: geni_spi_transfer: 888000.spi: len=16 m_cmd=0x00000003
71.364096: geni_spi_tx_data: 888000.spi: tx_len=16 tx_rem=0 data=56 f1
