tegra124_clock_init(9)

🌸 tegra124_clock_init(9) — from the Kernel API Manual 💅

okay so bestie, grab your iced coffee, because we're talking about tegra124_clock_init — the Tegra124-specific clock initialization girlie. she's in the kernel API manual, she's iconic, she's lowkey the reason your SoC clocks even wake up in the morning. ✨

✨ NAME ✨

tegra124_clock_init — Tegra124-specific clock initialization. that's it, that's the vibe. 🎀

---

🦋 SYNOPSIS 🦋

void tegra124_clock_init (struct device_node *np );

no cap, that's the whole signature. she returns nothing, she takes one thing, she slays. 💅

---

💖 ARGUMENTS 💖

• np — a struct device_node * pointing at the DT node for the SoC CAR IP block. that's her one (1) job: know which device tree node she's working with. 🫶

---

👑 DESCRIPTION 👑

so here's the tea, bestie: this function registers most of the SoC clocks for the Tegra124 system-on-chip. most of this code is shared between the Tegra124 and Tegra132 SoCs, although some of the initial clock settings and CPU clocks differ — yes, they're siblings, not twins, and the differences are real. 👯

she's intended to be called by the OF init code when a DT node with the "nvidia,tegra124-car" string is encountered, and she's declared with CLK_OF_DECLARE. so the OF init code sees that magic string, and boom — she gets summoned. 🪄

no return value. none. zero. she gives nothing back and honestly? main character energy. 💀
