Tested this on IB-NAS6210 (kirkwood, single GBE interface). Using mv643xx_eth as a module works again now and yields # cat /sys/kernel/debug/clk/tclk/ge[01]/clk_enable_count 2 1 as expected. - Simon -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
