omap_hwmod_setup_one(9)

💅 omap_hwmod_setup_one(9) — Kernel API Manual ✨

🌸 NAME 🌸

omap_hwmod_setup_one — set up a single hwmod. That's the whole assignment, bestie. 🫶

🦋 SYNOPSIS 🦋

int omap_hwmod_setup_one (const char *oh_name );

🎀 ARGUMENTS 🎀

• oh_name — const char * name of the already-registered hwmod to set up. Like, it has to be already registered — don't roll up with a random string and expect main character magic. 💅

✨ DESCRIPTION ✨

Okay so omap_hwmod_setup_one initializes and sets up a single hwmod. She's intended to be used for a small number of early devices, such as the timer IP blocks used for the scheduler clock. So this is very much "small guest list only" energy — not the whole hwmod fleet. ⏰✨

⚠️ Timing tea, no cap: this function must be called after omap2_clk_init. Do not skip that step, bestie. 😭

She resolves the struct clk names to struct clk pointers for each registered omap_hwmod. Also calls _setup on each hwmod. Returns -EINVAL upon error or 0 upon success. So when you see 0, that's the slay. When you see -EINVAL, that's the "not me crying in kernel" moment. 💀💖
