arm64: Add DTS support for FSL's LS2085A SoC
This patch adds the device tree support for FSL LS2085A SoC based on ARMv8 architecture. Following levels of DTSI/DTS files have been created for the LS2085A SoC family: - fsl-ls2085a.dtsi: DTS-Include file for FSL LS2085A SoC. - fsl-ls2085a-simu.dts: DTS file for FSL LS2085a software simulator model. In addition, this patch adds build support for FSL's LS2085A simulator model in arm64 dts Makefile.
