_ensure_mpu_hwmod_is_setup(9)

💅 _ensure_mpu_hwmod_is_setup(9) 💅

okay so welcome to the Kernel API Manual page for _ensure_mpu_hwmod_is_setup(9). This is the little behind-the-scenes helper that makes sure the MPU subsystem's hwmod data is init'ed and set up. Let's get into it, bestie 🫶✨

🌸 NAME 🌸

_ensure_mpu_hwmod_is_setup — ensure the MPU SS hwmod is init'ed and set up. Periodt. 💅

✨ SYNOPSIS ✨

void _ensure_mpu_hwmod_is_setup (struct omap_hwmod *oh );

🎀 ARGUMENTS 🎀

• oh — pointer to the hwmod currently being set up (usually not the MPU). So it's the hwmod you're dealing with right now, and most of the time it is not the MPU. 💖

🦋 DESCRIPTION 🦋

Okay so here's the tea: if the hwmod data corresponding to the MPU subsystem IP block hasn't been initialized and set up yet, do so now. This must be done first, since sleep dependencies may be added from other hwmods to the MPU. It's intended to be called only by omap_hwmod_setup*(). And there is no return value — it's void, so don't wait around for a little gift back, bestie. 🎁

⚠️ Behind-the-scenes helper alert: it's intended to be called only by omap_hwmod_setup*(), so don't just sprinkle it around like confetti, okay? 💀
