-Subject: [PATCH 16/25] MIPS: ralink: mt7620: fix usb issue during frequency
- scaling
-
-If the USB HCD is running and the cpu is scaled too low, then the USB stops
-working. Increase the idle speed of the core to fix this if the kernel is
-built with USB support.
-
-The values are taken from the Ralink SDK Kernel.
