There is no "fsl,ls1028a-gpu" compatible string. It is solely for the proprietary driver which will never be open source. Lately, linux gained support for the open source etnaviv driver for the GPU (although there is still support for the DisplayPort PHY missing to get actual graphics output). Thus, instead of supporting some proprietary driver, switch over to the open source one, which also have an official device tree binding.
