Subject: [PATCH v2 20/34] media: iris: add video hardware internal buffer count and size calculation
Date: Mon, 18 Dec 2023 17:02:15 +0530
Message-Id: <1702899149-21321-21-git-send-email-quic_dikshita@quicinc.com>
In-Reply-To: <1702899149-21321-1-git-send-email-quic_dikshita@quicinc.com>
References: <1702899149-21321-1-git-send-email-quic_dikshita@quicinc.com>
Precedence: bulk

Video driver needs various kind of internal buffers for
frame processing. Internal buffer size calculation depends
on hardware architecture, color format, resolution and codec.

Add APIs to calculate min count and size of different
internal buffers for different codecs for iris3.
