This patch fixes two problems: - 1) The device tree isn't currently providing sti-ethclk which is required by the dwmac glue code to correctly configure the ethernet PHY clock speed. This means depending on what the bootloader/jtag has configured this clock to, and what switch/hub the board is plugged into you most likely will NOT successfully negotiate a ethernet link. 2) The stmmaceth clock was associated with the wrong clock. It was referencing the PHY clock rather than the interconnect clock which clocks the IP. This patch also brings us closer to not having to boot the upstream kernel with the clk_ignore_unused parameter.
