linux.git/Documentation/devicetree/bindings/gpu, branch v5.8

Merge tag 'devicetree-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2020-06-05T03:11:25+00:00

Pull devicetree updates from Rob Herring:

 - Convert various DT (non-binding) doc files to ReST

 - Various improvements to device link code

 - Fix __of_attach_node_sysfs refcounting bug

 - Add support for 'memory-region-names' with reserved-memory binding

 - Vendor prefixes for Protonic Holland, BeagleBoard.org, Alps, Check
   Point, Würth Elektronik, U-Boot, Vaisala, Baikal Electronics,
   Shanghai Awinic Technology Co., MikroTik, Silex Insight

 - A bunch more binding conversions to DT schema. Only 3K to go.

 - Add a minimum version check for schema tools

 - Treewide dropping of 'allOf' usage with schema references. Not needed
   in new json-schema spec.

 - Some formatting clean-ups of schemas

dt-bindings: gpu: mali-utgard: add mediatek, mt7623-mali compatible

2020-05-16T19:03:06+00:00

The MediaTek MT7623 SoC contains a Mali-450, so add a compatible for it
and define its own vendor-specific properties.

dt-bindings: mali-midgard: Allow dma-coherent

2020-05-15T03:16:29+00:00

Add the boolean dma-coherent property to the list of allowed properties,
since some boards (Arm Juno) integrate the GPU this way.

dt-bindings: gpu: add power-domains #cooling-cells to arm,mali-bifrost.yaml

2020-05-11T22:25:14+00:00

A test with the command below gives this error:

arch/arm64/boot/dts/rockchip/px30-evb.dt.yaml: gpu@ff400000:
'#cooling-cells', 'power-domains'
do not match any of the regexes: 'pinctrl-[0-9]+'

With the conversion to yaml it also filters things
in a node that are used by other drivers like
'#cooling-cells' and 'power-domains'
for Rockchip px30 gpu nodes,
so add them to 'arm,mali-bifrost.yaml'.

dt-bindings: gpu: mali-utgard: Add the #cooling-cells property

2020-04-20T22:22:21+00:00

The GPU can be one of the big heat sources on a SoC. Allow the
"#cooling-cells" property to be specified for ARM Mali Utgard GPUs so
the GPU clock speeds (and voltages) can be reduced to prevent a SoC from
overheating.

dt-bindings: Clean-up schema indentation formatting

2020-04-16T21:59:22+00:00

Fix various inconsistencies in schema indentation. Most of these are
list indentation which should be 2 spaces more than the start of the
enclosing keyword. This doesn't matter functionally, but affects running
scripts which do transforms on the schema files.

dt-bindings: Add missing 'additionalProperties: false'

2020-03-31T15:03:17+00:00

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

dt-bindings: Clean-up schema errors due to missing 'addtionalProperties: false'

2020-03-27T14:27:58+00:00

Numerous schemas are missing 'additionalProperties: false' statements which
ensures a binding doesn't have any extra undocumented properties or child
nodes. Fixing this reveals various missing properties, so let's fix all
those occurrences.

Fix all the warnings in the DT binding schema examples when built with
'W=1'. This is in preparation to make that the default for examples.
