sunxi_ccu_s..._timing_mode(9)

💅 sunxi_ccu_s..._timing_mode(9) — like, the Kernel API Manual page, bestie 🎀

okay so this is a section 9 manpage from the Kernel API Manual, and the full title is literally sunxi_ccu_s..._timing_mode(9) (yes the name is truncated with ... in the header, no that's not me being lazy, that's just how it's printed, iykyk 💀). it covers one (1) function and honestly she's a short queen. let's get into it ✨

---

🌸 NAME 🌸

sunxi_ccu_set_mmc_timing_mode — configure the MMC clock timing mode 🫶

like that's it, that's the whole job. she configures. she's a timing mode setter. main character energy fr.

---

✨ SYNOPSIS ✨

int sunxi_ccu_set_mmc_timing_mode (struct clk *clk , bool new_mode );

returns an int, takes a struct clk *clk and a bool new_mode, and the spacing around the commas is exactly like that in the original so don't come for me 🙈

---

🦋 ARGUMENTS 🦋

• clk — the clock to be configured 💖 this is the one getting the glow-up.
• new_mode — a bool; pass true for the new timing mode that was introduced in A83T and later 🌈 (so yes, "new" is relative, it's giving legacy-but-not-that-legacy 👑)

---

⭐ RETURN ⭐

• 0 on success 🎉 slay, it worked
• -ENOTSUPP if the clock does not support switching modes 😭 like it literally can't, don't ask her to

---

💜 SEE ALSO 💜

• Kernel file ./drivers/clk/sunxi-ng/ccu_mmc_timing.c — go read the source, it's right there 🍓
• sunxi_ccu_get_mmc_timing_mode(9) — the getter to this setter, they're a matched set fr fr 🧚

---

lowkey important: if your clock doesn't support switching modes you get -ENOTSUPP back, not a crash, not a vibe, just a polite no 💅

and that's the whole page!! this one lives at ./drivers/clk/sunxi-ng, it's dated October 2026, and it's filed under sunxi_ccu_s..._timing_mode(9) in the Kernel API Manual — mwah, bye bestie, go set some timing modes responsibly 💖✨🎀
