🌸 NAME 🌸

rza1_set_mux — grab pins from a group and slap their mux settings on them 🫶

like, it retrieves pins from a group and applies their mux settings, no cap. that's the whole vibe.

✨ SYNOPSIS ✨

int rza1_set_mux (struct pinctrl_dev *pctldev , unsigned int selector ,
       unsigned int group );

returns an int, takes three args, and yes the spacing is exactly like that, don't come for me, that's just how it's written 💀

🦋 ARGUMENTS 🦋

  • pctldev — the pin controller device 👑 this is your main character, the pinctrl device the whole thing operates on.
  • selector — the function selector 🎯 the function you're picking, iykyk.
  • group — the group selector 🌈 which group of pins you're repping.

three args, very demure, very mindful 🧚
