That's not related to the commit.

Combine relevant patches into one patchsets, so we see entire picture. Best regards, Krzysztof

The IMG BXM-4-64 GPU is integrated into the T-Head TH1520 SoC. This commit adds the compatible string "img,img-bxm-4-64" to the device tree match table in the drm/imagination driver, enabling support for this GPU. By including this GPU in the compatible devices list, the driver can initialize and manage the BXM-4-64 GPU on the TH1520 SoC, providing graphics acceleration capabilities upstream. This commit doesn't touch the img,powervr-rogue.yaml on purpose, as the new dt-bindings schema was proposed [1], but not merged yet.
