Date: Mon, 25 May 2015 11:55:43 +0200 From: Richard Cochran <richardcochran@...il.com> To: <netdev@...r.kernel.org> Cc: David Miller <davem@...emloft.net>, Christian Riesch <christian.riesch@...cron.at>, Stefan Sorensen <stefan.sorensen@...ctralink.com> Subject: [PATCH net 1/3] net: dp83640: fix broken calibration routine. Currently, the calibration function that corrects the initial offsets among multiple devices only works the first time. If the function is called more than once, the calibration fails and bogus offsets will be programmed into the devices. In a well hidden spot, the device documentation tells that trigger indexes 0 and 1 are special in allowing the TRIG_IF_LATE flag to actually work. This patch fixes the issue by using one of the special triggers during the recalibration method.
