bcm63xx_select_phy_mode(9)

💅 bcm63xx_select_phy_mode(9) — the Kernel API Manual bestie era 💖

🌸 NAME 🌸

bcm63xx_select_phy_mode — Select between USB device and host mode.

✨ SYNOPSIS ✨

Omg okay here's the exact incantation, bestie, no cap:

void bcm63xx_select_phy_mode (struct bcm63xx_udc *udc , bool is_device
       );

🎀 ARGUMENTS 🎀

• udc — Reference to the device controller.
• is_device — true for device, false for host. Pick your era 👑

🦋 DESCRIPTION 🦋

Lowkey this should probably be reworked to use the drivers/usb/otg infrastructure — yes, that's literally the note, bestie 😭.

By default, the AFE/pullups are disabled in device mode, until bcm63xx_select_pullup is called. That's the whole default vibe check.
