Subject: [PATCH 5/7] media: dt-bindings: allwinner: document H6 Hantro G2 binding
Date: Mon, 22 Nov 2021 19:47:00 +0100	[thread overview]
Message-ID: <20211122184702.768341-6-jernej.skrabec@gmail.com> (raw)
In-Reply-To: <20211122184702.768341-1-jernej.skrabec@gmail.com>

Allwinner H6 contains older Hantro G2 core, primarly used for VP9 video
decoding. It's unclear for now if HEVC is also supported.

Describe it's binding.
