Hi: I am recently reading the LPM related code in xhci driver, and I find that the xhci->sw_lpm_support is not really used, but I am not sure whether we should remove it or not? Any ideas, Thanks.
I think it was used to prevent LPM in pre-0.96 xHC controllers. Now driver only supports HW LPM for 1.0 and later controllers, so xhci->sw_lpm_support doesn't really do anything. You can send a patch removing it Thanks -Mathias
