Welcome to the Kernel API Manual, bestie ✨ — this page is all about zl3073x_update_hwreg(9) and it's lowkey iconic 💅.

🌸 NAME 🌸

zl3073x_update_hwreg — Update certain bits in HW register

✨ SYNOPSIS ✨

int zl3073x_update_hwreg (struct zl3073x_dev *zldev , u32 addr , u32
       value , u32 mask );

🎀 ARGUMENTS 🎀

• zldev — zl3073x device pointer 🫶
• addr — HW register address 📍
• value — Value to be written into HW register ✍️
• mask — Bitmask indicating bits to be updated 🎯

💖 DESCRIPTION 💖

Okay so the vibe is: it reads the given HW register, updates the requested bits specified by value and mask, and writes the result back to the HW register. That's the whole flow, no cap 💅✨.

🔥 RETURN 🔥

0 on success, <0 on error 😭 — yes bestie, that's the return contract exactly.
