✨ cdns3_set_register_bit — kernel API manual energy ✨

okay bestie, so this page is cdns3_set_register_bit(9) from the kernel API manual, and honestly? she's small but she's mighty. lowercase function, uppercase vibes. let's get into it 💅

---

🌸 NAME 🌸

cdns3_set_register_bit — literally sets a bit in the given register. that's it. that's the whole job. and she does it flawlessly.

---

🎀 SYNOPSIS 🎀

void cdns3_set_register_bit (void __iomem *ptr , u32 mask );

no return value, no drama, just vibes and a bit flip 🦋

---

💖 ARGUMENTS 💖

• ptr — the address of the device controller register that's gonna get read and then changed. yes, read and changed. she's a read-modify-write situation, iykyk ✨
• mask — the bits you're requesting to set. like, the specific bits. not all of them. be precise, bestie 🎯
