9796853e9 ARM: STi: DT: Properly define sti-ethclk & stmmaceth for stih415/6 ... Browse Code »

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.
