[OpenWrt-Devel] [PATCH 3/3 v3] ARM: dts: Add devicetree for Storlink/Storm SL93512R
Linus Walleij

Wed Jul 11 15:47:20 EDT 2018
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.
Signed-off-by: Linus Walleij <linus.walleij at linaro.org>

ChangeLog v2->v3:
- Use a fixed link for the ethernet port to the Vitesse
DSA router chip.
ChangeLog v1->v2:
- Rename wrongly named "ethernet-phy" to "mdio"
- Drop device_type from the ethernet phy
