[PATCH 0/2] Add trace events for Qualcomm GENI I2C drivers

[Praveen Talari]

Add a new trace event header providing tracepoints for the Qualcomm
GENI I2C controller.

The trace events cover controller bus setup, interrupt status and 
error reporting. These events enable structured debugging and performance
analysis using ftrace.

Usage examples:

Enable all I2C traces:
echo 1 > /sys/kernel/tracing/events/i2c/enable
echo 1 > /sys/kernel/tracing/events/qcom_geni_i2c/enable

cat /sys/kernel/debug/tracing/trace_pipe

Example trace output:
79.737075: i2c_write: i2c-11 #0 a=057 f=0200 l=3 [00-00-3f]
79.737075: geni_i2c_bus_setup: a90000.i2c: clk_freq=400000 clk_div=2
   t_high=5 t_low=11 t_cycle=22
79.737084: geni_i2c_irq: a90000.i2c: m_stat=0x40000000 rx_st=0x00000000
   dm_tx=0x00000000 dm_rx=0x00000000
79.737201: geni_i2c_irq: a90000.i2c: m_stat=0x00000001 rx_st=0x00000000
   dm_tx=0x00000000 dm_rx=0x00000000
79.737211: i2c_result: i2c-11 n=1 ret=1
