__zynqmp_clock_get_parents(9)

💅 __zynqmp_clock_get_parents — the Kernel API Manual, but make it cute

okay so bestie, this is a kernel function from the ZynqMP clock driver (./drivers/clk/zynqmp/clkc.c), and it's literally just vibing in the kernel API manual. it's giving "lowkey important, highkey niche" 💖

---

✨ NAME ✨

__zynqmp_clock_get_parents — get parents info of clock from firmware response data 🎀

like, the firmware sent you a little package of parent-clock data and this function is the one that unpacks it. no cap.

---

🌸 SYNOPSIS 🌸

int __zynqmp_clock_get_parents (struct clock_parent *parents , struct
parents_resp *response , u32 *nparent );

---

🦋 ARGUMENTS 🦋

• parents — clock parents, aka the place where the parent info is gonna live. it's a struct clock_parent *, periodt 🫶
• response — clock parents data received from firmware. this is the raw tea straight from the firmware, struct parents_resp * 💌
• nparent — number of parent. literally the count of parents, u32 *, iconic 🌈

---

⭐ RETURN ⭐

0 on success, else error+reason 😭 — so if you get anything other than 0, that's your sign something went sideways and there's a reason attached.

lowkey reminder: this page is from the ./drivers/clk/zynqmp corner of the kernel and it's dated October 2026, so bestie, that's the version tea — don't come for me if your tree is different, fr fr 🙈

stay slay, go read your kernel source 💜✨
