Subject: Re: [PATCH v6 0/5] Add SS/HS-USB changes for Qualcomm SM8150 chipset
Hi Kishon/Vinod,
Is this series good, and can be picked up? Noticed that there was
another recent change to the QMP PHY driver as well:
https://patchwork.kernel.org/cover/11514761/
Did you want me to rebase my changes on top of that, or the current
changes are sufficient?
Thanks
Wesley
