[OpenWrt-Devel] [PATCH] ramips mt7620: ArcherC20i USB support and more

[Gunnar Thorburn]

Hi,

The patch (actually the entire file) was contributed on the OpenWrt 
forum:
https://forum.openwrt.org/viewtopic.php?pid=281794#p281794
My contribution is that I have tested it and that I am trying to submit 
it here.

I can confirm that:
  1) My ArcherC20i works fine with the patch applied
  2) USB works (which it does not do in CC without the patch)

If the changes not related to USB (ehci/ohci) are questionable, I would 
be happy to resubmit a patch for just USB. I am sorry about the spaces 
and tabs. The clean patch below looks much nicer.

   Gunnar T.
