Subject: [PATCH v5 1/3] media: dt-binding: media: Add rk3568-vepu binding
Date:   Sun, 12 Jun 2022 17:53:44 +0200

The RK3568 and RK3566 have a Hantro VPU node solely dedicated to
encoding. This patch adds a new binding to describe it, as it
does not really fit the rockchip-vpu binding, since there is no
decoder.
