| |
Defines VBUS detect and VBUS boost for the QCS404 EVB.
Detect: VBUS present/absent is presented to the SoC via a GPIO on the EVB. Define the pin mapping for later use by gpio-usb-conn.
Boost: An external regulator is used to trigger VBUS on/off via GPIO. This patch defines the relevant GPIO in the EVB dts.
