[PATCH 0/4] STi device-tree display subsystem rework

[PATCH 0/4] STi device-tree display subsystem rework

[Raphael Gallais-Pou]

This serie aims to rework the display-subsystem node, which was
previously included directly within the SoC node.  This was wrong
because it is an abstraction and describes how IPs behave together, not
what the hardware is.  Instead, extract display-subsystem outside of the
SoC node, and let IPs describe their connections.  Doing so helps the
readability, and eases the understanding of the hardware.

Several nodes have been renamed to stick to the generic names defined in
the device-tree specification.

This series depends on another sent a few days ago.  It is not critical
though, since not having it only triggers warnings when building
deprecated device-trees.  Please see link below.

[PATCH 1/4] drm/sti: check dma_set_coherent_mask return value

[Raphael Gallais-Pou]

Return value for DMA allocation was not checked.  Check it and return
error code in case of failing.

[PATCH 2/4] drm/sti: make use of drm_of_component_probe

[Raphael Gallais-Pou]

Enhance the probing sequence by using the ports property of the
display-subsystem node.

That done, it becomes possible to handle the display-substem node
outside of the soc node within the device-tree and not have each IP
blocks as children of the display-subsystem node.

[PATCH 3/4] ARM: dts: sti: extract display subsystem out of soc

[Raphael Gallais-Pou]

The display subsystem represent how IPs are interacting together and
have nothing to do within the SoC node.

Extract it from the SoC node and let IPs nodes in the Soc node.

Several nodes did not use conventional name:
 * sti-display-subsystem -> display-subsystem
 * sti-controller -> display-controller
 * sti-tvout -> encoder
 * sti-hda -> analog
 * sti-hqvdp -> plane

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: base-commit b9a572f471993d3e8bf874fcb57f331d66650440 not known, ignoring
 Base: attempting to guess base-commit...
 Base: tags/v6.16-rc1-11-g2436e190bbdd (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
