When we're debugging hard-to-reproduce and time-sensitive use cases, printk() poses too much overhead. That's when the kernel's tracing infrastructure comes into play. This patch implements a few initial tracepoints for the dwc3 driver. More traces can be added as necessary in order to ease the task of debugging dwc3.

# Platform-specific glue layers go here

# NOTICE: Make sure your glue layer doesn't depend on anything
|
|
# which is arch-specific and that it compiles on all situations.
|
|
#
|
|
# We want to keep this requirement in order to be able to compile
|
|
# the entire driver (with all its glue layers) on several architectures
|
|
# and make sure it compiles fine. This will also help with allmodconfig
|
|
# and allyesconfig builds.
