Subject: kirkwood: Add missing phy-mode and fixed links
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fff9316268e44d70cd618d32376a085ab8205e89;p=openwrt%2Fstaging%2Fthess.git

kirkwood: Add missing phy-mode and fixed links

Copied from original Andrew's Lunn commit message:

    The DSA framework has got more picky about always having a phy-mode
    for the CPU port. The Kirkwood Ethernet is an RGMII port. Set the
    switch to impose the RGMII delays.

    Additionally, the cpu label has never actually been used in the
    binding, so remove it.

This commit backport change from upstream and fix downstream EA3500 dts.
