From: Thierry Reding <treding@xxxxxxxxxx> Hi, this series of patches is an attempt to split up JC's large patch adding ELPG support into more manageable chunks. The original patch can be found here: http://patchwork.ozlabs.org/patch/1115804/ That patch was part of a larger series that also added a couple more features to more aggressively save power. This series is more limited in scope and at the same time tries to address most of the comments that were voiced during review of JC's original posting. Note that this series is primarily targetted at getting system suspend and resume to work properly on Jetson TX2 and later, now that we can actually resume from system sleep on these systems. The code should also work on Tegra210 and earlier, though Tegra210 is still missing a bit of the very low-level plumbing to make the system resume properly from sleep. I've verified that after this I can successfully use the XHCI on Jetson TX2 after a system suspend/resume cycle. Note that I've claimed ownership of these patches because they differ from JC's patches significantly in many areas and are also a bit crippled compared to JC's original in terms of features. I've credited JC in the commit message, but didn't want him to get any blame from me potentially messing this up. JC, if you think this is still in line with what you had in mind, let me know and I'll restore your authorship.
