<id>urn:sha1:64bc5bd055a0b8cf96328287a8d60facdaae9edf</id>
<content type='text'>
Arm has introduced a new v10 GPU architecture that replaces the Job Manager
interface with a new Command Stream Frontend. It adds firmware driven
command stream queues that can be used by kernel and user space to submit
jobs to the GPU.

Add the initial schema for the device tree that is based on support for
RK3588 SoC. The minimum number of clocks is one for the IP, but on Rockchip
platforms they will tend to expose the semi-independent clocks for better
power management.

v6:
- Add Maxime's and Heiko's acks

v5:
- Move the opp-table node under the gpu node

v4:
- Fix formatting issue

v3:
- Cleanup commit message to remove redundant text
- Added opp-table property and re-ordered entries
- Clarified power-domains and power-domain-names requirements for RK3588.
- Cleaned up example

Note: power-domains and power-domain-names requirements for other platforms
are still work in progress, hence the bindings are left incomplete here.

v2:
- New commit

The Imagination PowerVR Series5 "SGX" GPU is part of several SoCs from
multiple vendors. Describe how the SGX GPU is integrated in these SoC,
including register space and interrupts. Clocks, reset, and power domain
information is SoC specific.

<content type='text'>
This binding will be used for GPUs starting from Series6 (Rogue)
and later. A different binding document will describe Series5.
With that the name "img,powervr" is too generic, rename to
"img,powervr-rogue" to avoid confusion.

Pull drm updates from Dave Airlie:
 "This contains two major new drivers:

   - imagination is a first driver for Imagination Technologies devices,
     it only covers very specific devices, but there is hope to grow it

   - xe is a reboot of the i915 GPU (shares display) side using a more
     upstream focused development model, and trying to maximise code
     sharing. It's not enabled for any hw by default, and will hopefully
     get switched on for Intel's Lunarlake.

  This also drops a bunch of the old UMS ioctls. It's been dead long
  enough.

  amdgpu has a bunch of new color management code that is being used in
  the Steam Deck.

<id>urn:sha1:f1d797b6da5e4a7cacc04eb9a49fe1a421169ff3</id>
<content type='text'>
When number of clock varies between variants, the Devicetree bindings
coding convention expects to have widest constraints in top-level
definition of the properties and narrow them in allOf:if:then block.

This is more readable and sometimes allows to spot some errors in the
bindings.
