[PATCH 2/6] ARM: dts: hummingboard/cubox-i: add USB OC pinctrl configuration

Russell King rmk+kernel at arm.linux.org.uk
Sat Aug 23 02:11:26 PDT 2014


Hummingboard has no over current hardware, so disable the over current
detection for both ports.

Cubox-i has over current hardware, so appropriately configure this.
