The power domains on the GX SoCs are very similar to G12A. The only known differences so far are: - The GX SoCs do not have the HHI_VPU_MEM_PD_REG2 register (for the VPU power-domain) - The GX SoCs have an additional reset line called "dvin" Add a new compatible string and adjust the reset line expectations for these SoCs.
