Subject: ipq806x: fix ethernet for Nokia AC400i
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8443da363ebe72161ddfd75d01ec67afe52d0f63;p=thirdparty%2Fopenwrt.git

ipq806x: fix ethernet for Nokia AC400i

In previous versions of OpenWrt, ethernet was partially working,
sometimes depending on initialization state left by bootloader.
Since the switch to NSS drivers, it is completely broken.

- swap GMAC to PHY address mapping
- use rgmii internal delay
- drop `fixed-link` rates
- add pinctrl settings for rgmii0
- declare reset GPIO 51 (used for both PHYs)
- disable hibernation
