[PATCH v5 1/3] media: dt-binding: media: Add rk3568-vepu binding

From: Nicolas Frattaroli
Date: Sun Jun 12 2022 - 11:54:44 EST


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.
