Subject: [PATCH v4 3/5] coresight: tmc: Update sink types for default selection.
Date: Tue, 26 May 2020 11:46:40 +0100 [thread overview]
Message-ID: <20200526104642.9526-4-mike.leach@linaro.org> (raw)
In-Reply-To: <20200526104642.9526-1-mike.leach@linaro.org>
An additional sink subtype is added to differentiate ETB/ETF buffer
sinks and ETR type system memory sinks.
This allows the prioritised selection of default sinks.
Signed-off-by: Mike Leach <mike.leach@linaro.org>
