pub const WIFI_SDIO: u32 = 9;Expand description
A WiFi radio on an SDIO host at a fixed SoC address (the Pi 4’s CYW43455 behind the Arasan, the
VisionFive 2 Lite’s AIC8800 behind a DesignWare dw_mmc). The
kernel grants the host’s window - and, where it can, the radio’s power control - to the service
whose request names this kind, never to a service because of its name.
