💅 zynqmp_pm_clock_getparent — the one from the Kernel API Manual (section 9), bestie 🎀

okay so picture this: you're deep in the kernel API manual, section 9, and you meet zynqmp_pm_clock_getparent. she's giving "small function, big main character energy" ✨ and honestly? she ate. this is the page that tells you how a master asks the firmware which parent a clock is currently vibing with. iykyk 🦋

✨ NAME ✨

zynqmp_pm_clock_getparent — literally just: get the clock parent for the given id 💖

🌸 SYNOPSIS 🌸

int zynqmp_pm_clock_getparent (u32 clock_id , u32 *parent_id );

look at her. three pieces. signature stays exactly like that, don't you dare touch the spacing, she's iconic 🫶

🦋 ARGUMENTS 🦋

  • clock_id — the ID of the clock. yes, that clock. the one you're being nosy about 👀
  • parent_id — the parent id. this is where the answer gets dropped off, so keep it safe, bestie 🎀

⭐ DESCRIPTION ⭐

so the whole lore here is short and sweet: this function is what a master calls when it wants to get the parent index for any clock. that's it. that's the vibe. she's a getter, she gets 💅

no drama, no side quests — just "hey firmware, what's this clock's parent index?" and the firmware says something back. periodt 🔥

🌈 RETURN 🌈
