prm_register(9)

✨ NAME ✨

okay bestie, welcome to prm_register(9) — she's straight out of the Kernel API Manual, and she registers per-SoC low-level data with the PRM 🎀

💖 SYNOPSIS 💖

int prm_register (struct prm_ll_data *pld );

Yep, she takes one argument and hands you back an int, periodt.

🫶 ARGUMENTS 🫶

• pld — low-level per-SoC OMAP PRM data & function pointers to register. This is the whole payload, bestie.

🔥 DESCRIPTION 🔥

Okay so here's the tea: prm_register registers per-SoC low-level OMAP PRM data and function pointers with the OMAP PRM common interface. Very main character energy, very “let me introduce myself to the common layer” 💅

The caller must keep the data pointed to by pld valid until it calls prm_unregister and it returns successfully. Like, actually returns successfully — no cap. Don't let that data go poof early 😭

Return vibe check:

• 0 — success, slay ✨
• -EINVAL — if pld is NULL
• -EEXIST — if prm_register has already been called without an intervening prm_unregister

bestie, if you already registered without unregistering first, that’s a -EEXIST situation. The kernel is literally telling you “girl, we’ve been here” 💀
