Subject: [PATCH v4 12/16] media: platform: mtk-mdp3: add the blend of component in MUTEX MOD
Date:   Wed, 8 Feb 2023 17:22:05 +0800
Message-ID: <20230208092209.19472-13-moudy.ho@mediatek.com>

Precedence: bulk

In further chips, some components will cooperate to achieve
advanced functions, and these MODs need to be set at the same time.
