What kind of patches are these ?
What sort of problem are those patches attempting to address ?

These seem to be randomly picked patches from Linux 4.7, 5.5 ... but 
there seem to be a huge amount of backports missing inbetween, which 
would create a tremendous maintenance burden of the DWC3 driver.

Can you please instead pick ALL the missing patches from Linux, so that 
the DWC3 driver is instead synchronized with Linux, rather than 
diverging and growing partial backports ?

It shouldn't be difficult, one approach I can think of is roughly this:
- figure out the original merge base from which the DWC3 driver was 
imported to U-Boot
- in U-Boot, revert all dwc3 patches on top of that import patch
- pick all Linux kernel dwc3 patches from that merge base and apply on 
top of this U-Boot with reverts
- Run rebase and drop the reverts, let git drop duplicate patches

Thank you
