From c6259c994ab55aa65b697a907c273b314d79a852 Mon Sep 17 00:00:00 2001 From: Pratik Patel Date: Mon, 3 Nov 2014 11:07:37 -0700 Subject: coresight-tpiu: add CoreSight TPIU driver This driver manages CoreSight TPIU (Trace Port Interface Unit) which acts as a sink. TPIU is typically connected to some offchip hardware hosting a storage buffer.
