Subject: [PATCH v1 12/18] media: uapi: Add a control for HANTRO driver
Date: Wed, 17 Feb 2021 09:03:00 +0100 [thread overview]
Message-ID: <20210217080306.157876-13-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210217080306.157876-1-benjamin.gaignard@collabora.com>
The HEVC HANTRO driver needs to know the number of bits to skip at
the beginning of the slice header.
That is a hardware specific requirement so create a dedicated control
that this purpose.
