From 26e24f1e97e732f9475d403c5e209c29fe403a12 Mon Sep 17 00:00:00 2001 From: Pratik Patel Date: Mon, 3 Nov 2014 11:07:36 -0700 Subject: coresight-tmc: add CoreSight TMC driver This driver manages CoreSight TMC (Trace Memory Controller) which can act as a link or a sink depending upon its configuration. It can present itself as an ETF (Embedded Trace FIFO) or ETR (Embedded Trace Router). ETF when configured in circular buffer mode acts as a trace collection sink. When configured in HW fifo mode it acts as link. ETR always acts as a sink and can be used to route data to memory allocated in RAM.
