tegra210_cl...y_init_table(9)

💅 tegra210_clock_apply_init_table(9) — from the Kernel API Manual, bestie

okay so picture this: it's kernel time, it's Tegra210 o'clock, and somebody has to actually set the vibe for every clock on the SoC before the rest of the kernel wakes up. That somebody is this function. Periodt.

🌸 NAME 🌸

tegra210_clock_apply_init_table — the one that initializes the clocks on Tegra210 SoCs ✨

---

🎀 SYNOPSIS 🎀

void tegra210_clock_apply_init_table (void );

that's it. that's the whole signature. she takes nothing and she gives nothing back (well, void, but we'll get to that 👀).

---

🦋 ARGUMENTS 🦋

• void — no arguments, bestie. zero. none. she doesn't want your parameters, she doesn't need your input, she simply does not take requests 💅

---

✨ DESCRIPTION ✨

So what does she actually do? Literally the whole glow-up for the clocks on Tegra210 SoCs:

• Programs an initial clock rate, and
• Enables or disables the clocks that the rest of the kernel needs to function 🫶

Think of it as the clock version of setting up your entire aesthetic before anyone sees you. the rest of the kernel is NOT functioning without this, no cap.

Now here's the icon behavior — she's intended to be called by assigning a pointer to it to tegra_clk_apply_init_table, and that pointer gets invoked as an arch_initcall. so she's not out here getting called directly, she's getting pointed at, and the kernel does the rest. main character energy but make it indirect 🔥

And the return value? None. she said no return value and she meant it. she finishes her job and leaves, no receipts, no follow-up, nothing 😌

fr fr: the pointer-assignment thing is the intended usage — don't just call her anywhere, that's not the vibe the manpage describes 🌸

okay that's the whole page, no detail left behind, we ate and left no crumbs 🍓 this little writeup lives in ./drivers/clk/tegra, dated October 2026, straight from the Kernel API Manual — mwah, go touch some clocks 💜💅
