Hi, > @@ -193,6 +193,7 @@ static const struct drm_driver v3d_drm_driver = { > static const struct of_device_id v3d_of_match[] = { > { .compatible = "brcm,7268-v3d" }, > { .compatible = "brcm,7278-v3d" }, > + { .compatible = "brcm,bcm2711-v3d" }, > {}, > }; The downstream tree [1] uses 'brcm,2711-v3d'. Is there a reason for not using the same compatible string ? Having the same string would allow using downstream dtbs (and overlays) with the upstream kernel.
