Revision 8c781bf77a339748839bfd5eedfe2ad3e0e05c4a authored by Albert Lee on 26 June 2007, 05:43:15 UTC, committed by Jeff Garzik on 02 July 2007, 14:12:34 UTC
Recently the PLL input clock of pata_pdc2027x is sometimes detected higer than expected (e.g. 20.027 MHz compared to 16.714 MHz). It seems sometimes the mdelay() function is not as precise as it used to be. Per Alan's advice, HT or power management might affect the precision of mdelay(). This patch calls gettimeofday() to mesure the time elapsed and calculate the PLL input clock accordingly.
