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. Signed-off-by: Linus Walleij <redacted> --- The driver has been merged to the DMA tree. The clock and reset lines are added with numerical values as we do not want to depend on <dt-bindings/*> headers in the merge window. Will be fixed post-rc1. --- arch/arm/boot/dts/gemini.dtsi | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)
