Re: [RESEND PATCH 1/1] arm64: dts: Add Variscite DART-SD410 Evaluation board dts
From: Leonid Segal

Hello,
Thank you very much for the tips.
I have updated the documentation and schematics of our web site.
I also tried to implement all other fixes, but seems that I cannot file the git
you are talking about.
The patches i sent were done to:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
and there is no -next branch.
I tried to check out the linaro git:
http://git.linaro.org/landing-teams/working/qualcomm/kernel.git
there is a -next branch, but the USB section is in old format.
I tried to complile the latest version from
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
the usb there in new format, but nothing works (even LEDS) on Dragonboard too.
So, I think I am missing something global on the way.
If you can help me with it, I will appreciate it.
Thank you, Leonid.
