Arch Linux USB3 Issues?

[decontainerized]

Hi! I flashed the SPI on my Rock64 4GB board so that I could boot from an external hard drive.

I then put ARM Arch Linux on the hard drive and it boots from the USB2 ports but the USB3 does not work at all. Regardless of what device I plug into it, even after the OS is running from the drive connected to USB2. It worked fine on Kernel 4.4 but seems to be broken in the latest.

Code:

Linux 4.17.2-1-ARCH #1 SMP Sun Jun 17 13:11:24 MDT 2018 aarch64 GNU/Linux

I see on ayu-fan's rock64 mainline kernel repo that there is a PR to fix USB3. 

Does anyone know when this fix will be applied to the mainline Linux kernel? 

Thanks!

I was able to get the USB 3 port working using the default archlinuxarm kernel (4.18 rc3) by replacing the rk3328-arm64.dtb file in the /boot/dtbs folder with the one from Ayufan's mainline kernel image.  https://github.com/ayufan-rock64/linux-m...l/releases

I'm sure there is a patch that needs to be applied somewhere upstream, but I wasn't able to locate the .dts files in this image in order to generate it.  Maybe Ayufan might point us in the right direction.

Nice! So I just replace the file and reboot? 

Thanks for the info!
