This will be conflict with my R-Car D3 support patch.
https://patchwork.kernel.org/patch/9982267/
The R-Car D3 patch is not applied into usb.git yet though...

Hi Felipe-san,

Could you resolve this conflict on your side?
Or, should this r8a7743/5 patch be rebased on the R-Car D3 patch?

When after resolved the conflict:
