cdns3_allow_enable_l1(9)

okay bestie, this page is from the Kernel API Manual, and the function is cdns3_allow_enable_l1(9) — it's giving tiny USB gadget gatekeeper energy 🎀✨

🌸 NAME 🌸

cdns3_allow_enable_l1 — enable/disable permits to transition to L1. no cap, that's the whole vibe 💅

✨ SYNOPSIS ✨

void cdns3_allow_enable_l1 (struct cdns3_device *priv_dev , int enable
);

🎀 ARGUMENTS 🎀

• priv_dev — the Extended gadget object, aka the device we're doing this little operation on 🫶
• enable — turns the permit to transition to L1 on or off, literally that's it bestie 🔥

🦋 DESCRIPTION 🦋

okay so here's the L1 permit tea ☕: if bit USB_CONF_L1EN is set and the device receives an Extended Token packet, then the controller answers with an ACK handshake ✨

if bit USB_CONF_L1DS is set and the device receives an Extended Token packet, then the controller answers with a NYET handshake 💀 that's the whole situation, iconic behavior honestly 👑
