00d9220ec5 dt-bindings: display: msm: gmu: move sram property to gpu bindings
The sram property was incorrectly added to the GMU binding when it
really belongs with the GPU binding instead. Let's go ahead and
move it.

While changes are being made here, let's update the sram property
description to mention that this property is only valid for a3xx and
a4xx GPUs. The a3xx/a4xx example in the GPU is replaced with what was
in the GMU.

b435f8b4f6 dt-bindings: drm/msm/gpu: document second interconnect
Some A3xx and all A4xx Adreno GPUs do not have GMEM inside the GPU core
and must use the On Chip MEMory (OCMEM) in order to be functional.
There's a separate interconnect path that needs to be setup to OCMEM.
Let's document this second interconnect path that's available. Since
there's now two available interconnects, let's add the
interconnect-names property.

b8be1cd9b0 drm/msm: drop interrupt-names
Each GPU core only uses one interrupt so we don't to look up
an interrupt by name and thereby we don't need interrupt-names.

720c3bb802 drm/msm: drop _clk suffix from clk names
Suggested by Rob Herring.  We still support the old names for
compatibility with downstream android dt files.

1db7afa491 drm/msm: drop qcom,chipid
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 that
we are still compatible with the gpu dt node from android device
kernels.

1a4a66ddc7 drm/msm: remove qcom,gpu-pwrlevels bindings
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 downstream android
dt files.

efdbd7345f dt-bindings: consolidate display related bindings
This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
