Huh, I don't think I would have cleaned up DT bindings in exchange for
adding driver code like this. But the code

Existing bindings for the gpu are based on the downstream android kgsl
driver (a subset of the downstream bindings). But that isn't really
how we want the upstream bindings to look.
For now we have held off on adding gpu nodes to upstream dt files, but
now that all the dependencies are in place f
This was never documented or used in upstream dtb. It is used by
downstream bindings from android device kernels. But the quirks are
a property of the gpu revision, and as such are redundant to be listed
separately in dt. Instead, move the quirks to the device table.

The original way we determined the gpu version was based on downstream
bindings from android kernel. A cleaner way is to get the version from
the compatible string.
Note that no upstream dtb uses these bindings. But the code still
supports falling back to the legacy bindings (with a warning), so
The plan is to use the OPP bindings. For now, remove the documentation
for qcom,gpu-pwrlevels, and make the driver fall back to a safe low
clock if the node is not present.
Note that no upstream dtb use this node. For now we keep compatibility
with this node to avoid breaking compatibility with
Suggested by Rob Herring. We still support the old names for
compatibility with downstream android dt files.
