Message-Id: <1458678202-3447-8-git-send-email-mathieu.poirier@linaro.org> Date: Tue, 22 Mar 2016 14:23:15 -0600 From: Mathieu Poirier <mathieu.poirier@...aro.org> To: linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 07/14] coresight: tmc: making disable function reusable When disabling a TMC in any mode it may not be automatically desirable to read the content of the trace buffer. It is the case when operating in Perf mode where the content of the trace buffer is dealt with prior to the TMC being disabled. As such moving the tmc_etb/etr_dump() functions out of the disable_hw callback and into the current sysFS interface.
