I don't think so. When debugging, I printed the actual clock frequencies, and they looked as expected. And "arch/powerpc/platforms/512x/clock.c" has this: 385 static struct clk fec_clk = { 386 .name = "fec_clk", 387 .flags = CLK_HAS_CTRL, 388 .reg = 0, 389 .bit = 13, 390 .calc = unity_clk_calc, 391 .parent = &ips_clk, 392 }; which looks OK to me.
