Subject: media: dt-bindings: rk3568-vepu: Add RK3588 VEPU121
From: Emmanuel Gil Peyrot <linkmauve@linkmauve.fr>
This encoder-only device is present four times on this SoC, and should
support everything the rk3568 vepu supports (so JPEG, H.264 and VP8
encoding). No fallback compatible has been added, since the operating
systems might already support RK3568 VEPU and want to avoid registering
four of them separately considering they can be used as a cluster.

Subject: media: hantro: Disable multicore support
Avoid exposing equal Hantro video codecs to userspace. Equal video
codecs allow scheduling work between the cores. For that kernel support
is required, which does not yet exist. Until that is implemented avoid
exposing each core separately to userspace so that multicore can be
added in the future without breaking userspace ABI.
This was written with Rockchip RK3588 in mind (which has 4 Hantro H1
cores), but applies to all SoCs.

Subject: media: hantro: Add RK3588 VEPU121
RK3588 handling is exactly the same as RK3568. This is not
handled using fallback compatibles to avoid exposing multiple
video devices on kernels not having the multicore disable
patch.

Subject: arm64: dts: rockchip: Add VEPU121 to RK3588
From: Emmanuel Gil Peyrot <linkmauve@linkmauve.fr>
RK3588 has 4 Hantro G1 encoder-only cores. They are all independent IP,
but can be used as a cluster (i.e. sharing work between the cores).
These cores are called VEPU121 in the TRM. The TRM describes one more
VEPU121, but that is combined with a Hantro H1. That one will be handled
using the VPU binding instead.
