dt-bindings: gpu: mali-bifrost: Add compatible for RZ/G3E SoC

2025-05-28T13:46:08+00:00

Add a compatible string for the Renesas RZ/G3E SoC variants that
include a Mali-G52 GPU. These variants share the same restrictions on
interrupts, clocks, and power domains as the RZ/G2L SoC, so extend
the existing schema validation accordingly.

dt-bindings: gpu: Add 'resets' property for GPU initialization

2025-04-24T10:07:37+00:00

All IMG Rogue GPUs include a reset line that participates in the
power-up sequence. On some SoCs (e.g., T-Head TH1520 and Banana Pi
BPI-F3), this reset line is exposed and must be driven explicitly to
ensure proper initialization.

To support this, add a 'resets' property to the GPU device tree
bindings.

dt-bindings: gpu: img: Add BXS-4-64 devicetree bindings

2025-04-15T11:21:49+00:00

Unlike AXE-1-16M, BXS-4-64 uses two power domains.

Like the existing AXE-1-16M integration, BXS-4-64 uses the single clock
integration in the TI k3-j721s2.

dt-bindings: gpu: img: Future-proofing enhancements

2025-04-15T11:21:49+00:00

The first compatible strings added for the AXE-1-16M are not sufficient to
accurately describe all the IMG Rogue GPUs. The current "img,img-axe"
string refers to the entire family of Series AXE GPUs, but this is
primarily a marketing term and does not denote a level of hardware
similarity any greater than just "Rogue".

The more specific "img,img-axe-1-16m" string refers to individual AXE-1-16M
GPU. For example, unlike the rest of the Series AXE GPUs, the AXE-1-16M
only uses a single power domain.

The situation is actually slightly worse than described in the first
paragraph, since many "series" (such as Series BXS found in the TI AM68
among others and added later in this series) contain cores with both Rogue
and Volcanic architectures.

Besides attempting to move away from vague groupings defined only
by marketing terms, we want to draw a line between properties inherent to
the IP core and choices made by the silicon vendor at integration time.
For instance, the number of power domains is a property of the IP core,
whereas the decision to use one or multiple clocks is a vendor one.

In the original compatible strings, we must use "ti,am62-gpu" to constrain
both of these properties since the number of power domains cannot be fixed
for "img,img-axe".

Work is currently underway to add support for volcanic-based Imagination
GPUs, for which bindings will be added in "img,powervr-volcanic.yaml".
As alluded to previously, the split between rogue and volcanic cores is
non-obvious at times, so add a generic top-level "img,img-rogue" compatible
string here to allow for simpler differentiation in devicetrees without
referring back to the bindings.

The currently supported GPU (AXE-1-16M) only requires a single power
domain. Subsequent patches will add support for BXS-4-64 MC1, which has
two power domains. Add infrastructure now to allow for this.

Also allow the dma-coherent property to be added to IMG Rogue GPUs, which
are DMA devices. The decision for coherency is made at integration time and
this property should be applied wherever it accurately describes the
vendor integration.

Note that the new required properties for power domains are conditional on
the new base compatible string to avoid an ABI break.

from all M lines."), Emma is no longer active in the Linux kernel and
dropped the V3D maintainership. Therefore, remove Emma as one of the DT
