Subject: [PATCH v2 7/9] media: hantro: IMX8M: add variant for G2/HEVC codec
Date: Thu, 18 Feb 2021 20:18:42 +0100 [thread overview]
Message-ID: <20210218191844.297869-8-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20210218191844.297869-1-benjamin.gaignard@collabora.com>
Add variant to IMX8M to enable G2/HEVC codec.
Define the capabilities for the hardware up to 3840x2160.
Retrieve the hardware version at init to distinguish G1 from G2.
