Subject: [PATCH 1/6] coresight: Change syncfreq to be a u8
Date: Mon, 11 Aug 2025 10:32:06 +0100 [thread overview]
Message-ID: <20250811-james-cs-syncfreq-v1-1-b001cd6e3404@linaro.org> (raw)
In-Reply-To: <20250811-james-cs-syncfreq-v1-0-b001cd6e3404@linaro.org>
TRCSYNCPR.PERIOD is the only functional part of TRCSYNCPR and it only
has 5 valid bits so it can be stored in a u8.
