This series covers 2 primary tasks:

1) Resubmit prior work:

[RESEND PATCH v5 3/4] arm64: dts: rockchip: Enable dmc and dfi nodes on gru.
https://lore.kernel.org/lkml/20210308233858.24741-2-daniel.lezcano@linaro.org/
[RESEND PATCH v5 2/4] arm64: dts: rk3399: Add dfi and dmc nodes.
https://lore.kernel.org/lkml/20210308233858.24741-3-daniel.lezcano@linaro.org/

This series was partially merged a while back, but the remaining 2
patches were blocked mostly on stylistic grounds (alpha/numerical
ordering).

2) Integrate many updates, bugfixes, and clarifications that were done
by Rockchip and Google engineers when first launching this platform.
Many of these were not integrated in the earlier series (e.g., the OPPs
changed before production; earlier patchsets used pre-production
numbers).

Along the way, it seemed worthwhile to convert the binding docs to a
schema. Among other reasons, it actually helped catch several errors and
omissions in translation between downstream device trees and the version
that actually landed upstream.

See the patches for further details.

Regards,
Brian
