Subject: [PATCH v6 06/12] media: platform: mtk-mdp3: chip config split about resolution limitations
Date:   Wed, 8 Feb 2023 17:08:49 +0800
Message-ID: <20230208090855.18934-7-moudy.ho@mediatek.com>
In-Reply-To: <20230208090855.18934-1-moudy.ho@mediatek.com>
References: <20230208090855.18934-1-moudy.ho@mediatek.com>

Precedence: bulk

Due to differences in hardware design, the supported max and min
resolutions and scaling capabilities will vary, and should be
integrated into specific config file.
