dt-bindings: gpu: mali-bifrost: Document nvmem for speedbin support

2023-03-31T09:43:30+00:00

Some SoCs implementing ARM Mali GPUs may be subject to speed binning
and the usable bin is read from nvmem: document the addition of nvmem
and nvmem-cells for 'speed-bin'.

dt-bindings: gpu: mali-bifrost: Add compatible for MT8195 SoC

2023-03-23T09:43:16+00:00

The MediaTek MT8195 SoC has a Mali G57 MC5 (Valhall-JM) and has the
same number of power domains and requirements as MT8192 in terms of
bindings.

dt-bindings: gpu: mali-bifrost: Add sub-schema for MT8192's power domains

2023-03-23T09:43:14+00:00

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.

dt-bindings: gpu: mali-bifrost: Fix power-domain-names validation

2023-03-23T09:43:13+00:00

Commit ("dt-bindings: gpu: mali-bifrost: Add Mediatek MT8183")
incorrectly introduced power domain names for MT8183, causing
validation issues.

Add power-domain-names to the base schema, allowing a maximum of
five elements; since platforms having a single power domain don't
need any actual domain name, disallow that for each sub-schema.

dt-bindings: gpu: mali-bifrost: Split out MediaTek power-domains variation

2023-03-23T09:43:11+00:00

In preparation for adding new bindings for new MediaTek SoCs, split out
the power-domains variation from the `else` in the current
mediatek,mt8183-mali conditional.

The sram-supply part is left in place to be disallowed for anything
that is not compatible with "mediatek,mt8183-mali" as this regulator
is MediaTek-specific and it is, and will ever be, used only for this
specific string due to the addition of the mediatek-regulator-coupler
driver.
