arm: dts: socfpga: use reset-name "stmmaceth-ocp" instead of "ahb"
[ Upstream commit 62a40a0d5634834790f7166ab592be247390d857 ]
The ahb reset is deasserted in probe before first register access, while the
stmmacheth-ocp reset needs to be asserted every time before changing the phy
mode in Arria10[1].
Changed in Upstream to "ahb"(331085a423b arm64: dts: socfpga: change the
reset-name of "stmmaceth-ocp" to "ahb" ).This change was intended for arm64
socfpga and it is not applicable to Arria10.
Further with STMMAC-SELFTEST Driver enabled, ethtool test also FAILS.
$ ethtool -t eth0
