musb_set_host(9)

🌸 NAME 🌸

hiii bestie 💖 welcome to musb_set_host(9) — straight outta the Kernel API Manual, and she's here to set and initialize host mode ✨ no cap.

✨ SYNOPSIS ✨

int musb_set_host (struct musb *musb );

🎀 ARGUMENTS 🎀

• musb — the musb controller driver data. that's the whole vibe 🫶

🦋 DESCRIPTION 🦋

okay so, at least some musb revisions need to enable the devctl session bit in peripheral mode to switch to host mode 👀 that's just how she goes.

This initializes things to host mode and sets A_IDLE 💅 and yeah, the SoC glue needs to advance state further based on the phy provided VBUS state — so the glue is doing its own little main character moment after this 🌈.

💀 heads up bestie: the SoC glue code may need to wait for musb to settle on enable before calling this, specifically to avoid babble. not me warning you about babble 😭 it's giving "please let her cook first."
