Subject: [PATCH v2 06/18] media: venus: firmware: Leave a clue for homegrown porters
Date: Thu, 04 May 2023 10:01:02 +0200 [thread overview]
Message-ID: <20230228-topic-venus-v2-6-d95d14949c79@linaro.org> (raw)
In-Reply-To: <20230228-topic-venus-v2-0-d95d14949c79@linaro.org>
Leave a clue about where the seemingly magic values come from, as it
is not obvious and requires some digging downstream..
