Subject: net: dp83640: fix broken calibration routine.
From: Richard Cochran <[email protected]>
[ Upstream commit 397a253af5031de4a4612210055935309af4472c ]
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.
