X-Git-Tag: v2019.10-rc4~6^2~9
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a3ce94b6024b93e7ab2ceaf7a6dc08c590bb3f5a;p=oweals%2Fu-boot.git

arm: dts: ls1028a-qds: define the MDIO MUX

Add the device-tree structure describing the MUX in board dts.

QDS board has an on-board RGMII PHY and 4 slots for extension cards.
All these can be accessed over MDIO through a MDIO MUX controlled
over I2C.
