Subject[PATCH v4 04/12] dt-bindings: gpu: mali-bifrost: Add sub-schema for MT8192's power domains
Date
MediaTek MT8192 (and similar) needs five power domains for the
Mali GPU and no sram-supply: change the binding to allow so by
also introducing power-domain-names in the generic binding;
while at it, also disallow the newly introduced power-domain-names
for all non-MediaTek bindings.

Fixes: 5d82e74a97c2 ("dt-bindings: Add compatible for Mali Valhall (JM)")

Since the changes are small, I kept the Reviewed-by tags that were
released on the previous version of this patch.
If that was wrong, please advertise so.
