✨ wm831x_set_bits(9) ✨

okay so bestie, welcome to the Kernel API Manual page for wm831x_set_bits(9) — yeah it's a section 9 page, that's the kernel API zone, we're with the drivers girlies now 💅

💖 NAME 💖

wm831x_set_bits — set the value of a bitfield in a WM831x register 🌸

like literally, you pick a register, you pick which bits (the mask), you hand over a value, and it sets them. no cap.

🎀 SYNOPSIS 🎀

int wm831x_set_bits (struct wm831x *wm831x , unsigned short reg ,
unsigned short mask , unsigned short val );

that's the whole signature, copied exactly, don't come for me about the spacing 🫶

👑 ARGUMENTS 👑

  • wm831x — the device you're writing to ✨ like, the actual WM831x chip you've got feelings about.
  • reg — the register you're writing to 💖 the one address that's getting the attention today.
  • mask — mask of bits to set 🎯 this is your little spotlight, it says which bits we're touching.
  • val — the value to set, and bestie listen: it's unshifted 😭 so don't go shifting it yourself and then acting surprised, iykyk.
ngl the unshifted note is the whole vibe check of this function — it's doing the shifting for you, that's the point. periodt.
