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 New warnings running 'make CHECK_DTBS=y for arch/arm64/boot/dts/ti/' for 20250310-sets-bxs-4-64-patch-v1-v3-0-143b3dbef02f@imgtec.com: arch/arm64/boot/dts/ti/k3-am625-verdin-wifi-dahlia.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-wifi-dev.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-beagleplay.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-wifi-mallow.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-wifi-ivy.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-nonwifi-dahlia.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-nonwifi-yavia.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-nonwifi-dev.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am62-lp-sk.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-wifi-yavia.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-nonwifi-mallow.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-phyboard-lyra-rdk.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-sk.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml# arch/arm64/boot/dts/ti/k3-am625-verdin-nonwifi-ivy.dtb: gpu@fd00000: power-domain-names: ['a'] is too short from schema $id: http://devicetree.org/schemas/gpu/img,powervr-rogue.yaml#
This GPU is found in the TI AM68 family of SoCs, with initial support added to the k3-j721s2 devicetree and tested on a TI SK-AM68 board. A suitable firmware binary can currently be found in the IMG linux-firmware repository[1] as powervr/rogue_36.53.104.796_v1.fw. No new UAPI will be necessary for this platform as it is sufficiently similar to the already supported AXE-1-16M. UMD support is close to being complete. We're now able to pass >90% of Vulkan conformance on our Mesa development branch. The compiler has been undergoing a significant rework needed to accomodate the BXS-4-64, as well as to make it more flexible to support additional Rogue GPUs going forward. The first part of this rework landed in Mesa in [2], and more MRs will follow in the coming weeks. There are several dt-bindings changes at the beginning of this series. We expect the result to be versatile enough to handle all Imagination Rogue GPUs while being a strong foundation to build bindings for the newer Volcanic architecture (for which we're currently developing support). The DTS changes at the end of the series are marked [DO NOT MERGE]. Once the series is reviewed, we will request these be taken through the relevant tree.
