Subject: ARM: dts: Add Gemini DMA controller
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9eeb02247723c2ce881319368ce22982f1c7b1ef;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: Add Gemini DMA controller

This adds the Faraday Technology FTDMAC020 DMA controller to
the Gemini SoC DTSI file. It is only used for memcpy work so
we can activate it for all users of the chipset.
