There's build-time dependencies throughout the series, so it'd be good if they can all go through either the PHY or USB trees. Kishon, Greg, any comments on these patches? Unfortunately, the USB patches in this series have a build-time dependency on the PHY patches, so this should all go through one tree. Since this all culminates in the XHCI driver, merging this through the USB tree might be best, provided that Kishon provides his Acked-by on the PHY patches. Alternatively, I can create a set of branches with the correct dependencies and send out pull requests for the three subsystems if that's preferrable. Let me know how you want to handle these. Thanks, Thierry

I have no objection for the usb patches to go through your tree as they are hardware-specific. thanks, greg k-h

Kishon, I haven't heard back from you on this yet. We missed v5.12 but I'd like to get this into v5.13 since it's the last missing piece to get suspend and resume working properly on a number of boards. Are you okay if I take this through the Tegra tree to satisfy the interdependencies between clk, PHY and USB patches? I've already got Acked-by's from the clock and USB maintainers. I want to tentatively take this into linux-next to give it a bit of soak time before the ARM SoC -rc6 cut-off. Please let me know if you'd prefer to apply these to your tree so I can back them out of the Tegra tree again. Thanks, Thierry

Yes please CC me on all things phy (MAINTAINERS should have told you so) If you can resend me and cc linux-phy@lists.infradead.org, I would take a look. FWIW since this goes thru Greg, the window closes earlier than merge window

For Tegra the patches go through ARM SoC and that usually means I have to send pull requests by -rc6. JC, do you have time to resend this batch this week? If not I can do it, too. Thierry
