Hi,
This patch series depends on:
https://patchwork.kernel.org/patch/11765789/
https://patchwork.kernel.org/patch/11760437/

USB nodes appear to finally be picked for the Qcom tree while the VQMMC LDO
is still pending.

I am still interested in this and was planning to send the updated
versions anyway soon.
I Will respin these and reorder the nodes.

Regards,
Robert
