[PATCH v2] ARM: dts: Add DTS file for D-Link DIR-685
Linus Walleij
linus.walleij at linaro.org
Sat Aug 5 14:44:36 PDT 2017
This adds a device tree file for the Gemini-based D-Link DIR-685
router, supporting all devices that are currently supported in
the main DTSI SoC file.

ChangeLog v1->v2:
- Drop bootargs, use stdout-path = "uart0:115200n8";
- Give sensible names to GPIO keys and GPIO LEDs
