What is the "raspberry_pi" integration?

I recently migrated from Supervised to HA OS 11 and the top integration on the list of integration startup times is consistently a “raspberry_pi” integration. When I click on the integration name to open the corresponding HA integration web page, I get a “This page does not exist” error:
My integrations list also does not show a “raspberry_pi” integration, only an “rpi_power” integration which I know is just the power supply checker integration.

What is the “raspberry_pi” integration?
