title: Plugin: GPIO
---
## Introduction
This plugin sets GPIO outputs either high or low before and/or after an
update has been deployed.
## GUID Generation
These device use GPIO `gpiochip_info.label` values, e.g.
* `GPIO\ID_INT3450:00`
## Quirk Use
This plugin uses the following plugin-specific quirks:
### GpioForUpdate
The GPIO bit to set before the update is deployed e.g. `INT3450:00,SPI_MUX,high`.
After the update has finished, the bits are returned to the default state.
For example, to set GPIO pin 2 low for the duration of the ColorHug device update
this could be added to the quirk file:
[USB\VID_273F&PID_1001]
GpioForUpdate=fake-gpio-chip,2,low
Since: 1.7.6
## External Interface Access
This plugin requires ioctl `GPIO_GET_CHIPINFO_IOCTL` and `GPIO_V2_GET_LINE_IOCTL`
access on `/dev/gpiochip*` devices.
## Version Considerations
This plugin has been available since fwupd version `1.7.6`.
