Subject: [PATCH 0/2] PATCH: firmware: ti_sci: Add trace events to TI SCI

Add trace events to help debug and measure the speed of the
communication channel.

Add parsing of the messages types but I am not sure how to parse the
flags, since the REQ and RESP flags conflict. Left as seperate commit to
make it easier to drop or make changes depending on comments.  The two
commits should squash easily.

Nishanth Menon and Vignesh Raghavendra requested I send this patch
upstream.
