Unlike the the very close A740 GPU on the SM8550 SoC, the A750 GPU doesn't have an HWCFG block but a separate register set. The missing registers are added in the a6xx.xml.h file that would require a subsequent sync and the non-existent hwcfg is handled in a6xx_set_hwcg(). The A750 GPU info are added under the adreno_is_a750() macro and the ADRENO_7XX_GEN3 family id. This adds: - the GMU and SMMU bindings - DRM driver changes - DT nodes Dependencies: None Tested using Mesa's !26934 Merge Request [0] on the SM8650-QRD and with kmscube & vkcube to test basic rendering.
