Rene Herman 055b93c9e3 USB: ehci: stop vt6212 bus hogging ... The VIA VT6212 defaults to only waiting 1us between passes over EHCI's async ring, which hammers PCI badly ... and by preventing other devices from accessing the bus, causes problems like drops in IDE throughput, a problem that's been bugging users of those chips for several years. A (partial) datasheet for this chip eventually turned up, letting us see how to make it use a VIA-specific register to switch over to the the normal 10us value instead, as suggested by the EHCI specification Solution noted by Lev A. Melnikovsky. It's not clear whether this register exists on other VIA chips; we know that it's ineffective on the vt8235. So this patch only applies to chips that seem to be incarnations of the (discrete) vt6212. Signed-off-by: Rene Herman <rene.herman@gmail.com> Tested-by: Lev A.
