From: Thierry Reding <treding@xxxxxxxxxx> Tegra XHCI controler can be placed in ELPG (Engine Level PowerGated) state for power saving when all of the connected USB devices are in suspended state. This patch series includes clk, phy and pmc changes that are required for properly place controller in ELPG and bring controller out of ELPG. I've rebased this on v5.12-rc2 and fixed two minor issues that checkpatch had pointed out. One of the patches compared to v7 was already merged into v5.12, so that rebased out. Greg, you had previously indicated[0] that you'd be willing for me to take the USB patches through the Tegra tree to resolve the complicated dependencies within this series, but I don't think you ever gave a formal Acked-by. Should I take your comments to be equivalent and just add them to the USB patches? Vinod, as discussed earlier, please take a look and provide an Acked-by if you're okay with me taking this through the Tegra tree for v5.13.
