-Subject: [PATCH 23/57] 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.
