Hello Soeren! It will take me some time to prepare a proper patch, I just found the documentation of your patman tool. I am using Guix and created a package definition for U-Boot with these three fixes using regexp substitutions.
My time is quite limited for this weekend. I guess that you would be much faster preparing these three simple changes as a patch. So I would be glad, if you prepare a patch. A proper commit message could be this: “This patch works around issues of low-speed USB keyboards with the dwc2 USB interface. There was a need to press a key when "USB0: scanning bus 0 for devices..." was printed or otherwise there was the error "Timeout poll on interrupt endpoint" and the keyboard was not usable. This patch reverts the workaround from 5da2dc9789abecb1b018beb0c93f4c38c2985bc6 for non-working keyboards.” Stefan > Am 29.02.2020 um 13:04 schrieb Soeren Moch <sm...@web.de>: > > > > On 29.02.20 00:46, Marek Vasut wrote: >> On 2/26/20 12:04 PM, Soeren Moch wrote: >>> Adding Marek as USB maintainer.
