tegra_dfll_register(9)

💖 NAME 💖

okay bestie, this is the tegra_dfll_register(9) page from the Kernel API Manual ✨ and it’s literally about probing a Tegra DFLL device. no cap.

tegra_dfll_register — probe a Tegra DFLL device 🎀

---

🌸 SYNOPSIS 🌸

int tegra_dfll_register (struct platform_device *pdev , struct tegra_dfll_soc_data *soc );

---

🦋 ARGUMENTS 🦋

• pdev — DFLL platform_device * 👑
• soc — per-SoC integration and characterization data for this DFLL instance 🫶

---

✨ DESCRIPTION ✨

so basically this probes and initializes a DFLL device instance 💅 it’s intended to be called by a SoC-specific shim driver that passes in per-SoC integration and configuration data via soc — iykyk.

it returns 0 on success or -err on failure. that’s the whole vibe check 😭

bestie, this is the “probe and initialize” moment. if it works you get 0; if it doesn’t, you get -err. periodt.
