Subject: ath79: fix eth0 PLL registers on WD My Net Wi-Fi Range Extender
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f36990eae77c3a22842a2c418378c5dd40dec366;p=openwrt%2Fstaging%2Fnbd.git

ath79: fix eth0 PLL registers on WD My Net Wi-Fi Range Extender

This replaces the register bits for RGMII delay on the MAC side in favor
of having the RGMII delay on the PHY side by setting the phy-mode
property to rgmii-id (RGMII internal delay), which is supported by the
at803x driver.  Speed 1000 is fixed as a result, so now all ethernet
speeds function.
