Subject: [PATCH v11 9/9] media: hantro: IMX8M: add variant for G2/HEVC codec
Date: Tue, 25 May 2021 18:12:38 +0200 [thread overview]
Message-ID: <20210525161238.1191168-10-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210525161238.1191168-1-benjamin.gaignard@collabora.com>
Add variant to IMX8M to enable G2/HEVC codec.
Define the capabilities for the hardware up to 3840x2160.
G2 doesn't have a postprocessor, uses the same clocks and has it
own interrupt.
