Subject: [PATCH v4 04/13] staging: media: starfive: Add a params sink pad and a scd source pad for ISP
Date: Tue, 2 Apr 2024 03:00:02 -0700 [thread overview]
Message-ID: <20240402100011.13480-5-changhuang.liang@starfivetech.com> (raw)
In-Reply-To: <20240402100011.13480-1-changhuang.liang@starfivetech.com>
StarFive ISP can use params sink pad to transmit ISP parameters and use
scd source pad to capture statistics collection data.
