💅 cdns_i2c_shutdown(9) 💅

okay so welcome to the Kernel API Manual page for cdns_i2c_shutdown(9), bestie. This is the little shutdown helper for the I2C controller vibes. 🦋

✨ NAME ✨

cdns_i2c_shutdown — prepare the I2C controller for system shutdown. 💖

🌸 SYNOPSIS 🌸

void cdns_i2c_shutdown (struct platform_device *pdev );

🎀 ARGUMENTS 🎀

• pdev — handle to the platform device structure. 🫶

🔥 DESCRIPTION 🔥

So what it does: it marks the adapter as suspended and resets the controller. That's the whole slay. Why? To make sure there's a clean handoff during system reboot or kexec. No messy leftover controller energy, periodt. 👑
