ARM: dts: Add devicetree for Storlink/Storm SL93512R
The Storlink Gemini324 EV-Board also known as Storm Semiconductor SL93512R_BRD is ground zero for the Gemini devices. We add a device tree so we can support it, it turns out to be pretty trivial. Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
