Hi,
I recently updated my meson-gxl-s805x-libretech-ac (la frite) board from
5.7 to 5.8, but USB seems to be broken? Given the USB phy warning, I
take it that this is related to commit 2f9139c2609fd71 (arm64: dts:
amlogic: use the new USB control driver for GXL and GXM)?
This is an unmodified 5.8.9 build of the aarch64 defconfig:

And then nothing.
I see similar issues on kernelci, E.G.:
https://storage.kernelci.org/chrome-platform/for-kernelci/v5.9-rc1-2-gf048ccd37a8b/arm64/defconfig/gcc-8/lab-baylibre/baseline-meson-gxl-s805x-libretech-ac.html
Before I dig deeper, am I missing something? Is this a known issue?
