omap_device_enable(9)

✨ omap_device_enable(9) — from the Kernel API Manual ✨

okay so bestie, this is a kernel API manual page, and it's literally about waking up an omap_device and making it fully alive 💅

---

🌸 NAME 🌸

omap_device_enable — fully activate an omap_device 🫶

🎀 SYNOPSIS 🎀

int omap_device_enable (struct platform_device *pdev );

🦋 ARGUMENTS 🦋

• pdev — the platform device you want to activate ✨ like, the one you're bringing to life, no cap

💖 DESCRIPTION 💖

So the way this works is: this function does whatever is necessary for the hwmods underlying the omap_device od to be accessible and ready to operate 🔥

What does "whatever is necessary" mean? Generally it involves:

• enabling clocks ⏰
• setting SYSCONFIG registers 📝
• and in the future it may involve remuxing pins 📍 (yes, future, as in not yet, don't come for me)

Heads up bestie: device drivers should call this function indirectly via pm_runtime_get*(). Like, that's the vibe — don't call it straight up, iykyk 🙈

Return values, listen up:

• Returns -EINVAL if you call it when the omap_device is already enabled 💀 (it's giving "girl, it's already on")
• Otherwise it passes along the return value of _omap_device_enable_hwmods 👑
