Subject: [PATCH 17/25] coresight: tmc-etr: Rearrange probing default buffer size
Date: Wed, 20 Mar 2019 18:49:34 +0000 [thread overview]
Message-ID: <1553107783-3340-18-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1553107783-3340-1-git-send-email-suzuki.poulose@arm.com>
As we are about to refactor the platform specific handling,
make the default buffer size probing generic.
