meson8_pmx_...other_groups(9)

💅 meson8_pmx_...other_groups(9) — the Kernel API Manual glow-up ✨

okay bestie, so this is a page from the Kernel API Manual (yes, the manual name is meson8_pmx_...other_groups(9) — the ellipsis is doing main character energy, we love that for it 🎀) and it's all about one little function that does one very specific thing. let's get into it 🦋

---

✨ NAME ✨

meson8_pmx_disable_other_groups — disables all the other groups that are using a given pin 💅 like, the pin picked its fave group and everyone else has to leave the group chat.

---

🌸 SYNOPSIS 🌸

void meson8_pmx_disable_other_groups (struct meson_pinctrl *pc ,
unsigned int pin , int sel_group );

note the void — this function returns literally nothing, it just does the thing and dips 😌

---

🫶 ARGUMENTS 🫶

• pc — the meson pin controller device, aka the whole vibe of the controller you're working with 🔥
• pin — the number of the pin, like its little ID card 🪪
• sel_group — the index of the selected group, or -1 if there isn't one 🙈

---

💖 DESCRIPTION 💖

so here's the tea ☕ — the function disables all pinmux groups that are using a pin, except the selected one. it's giving "you can stay, everyone else out" 🚪✨

and if sel_group is -1? then all the groups get disabled, which leaves the pin chilling in GPIO mode. no groups, no drama, just GPIO 🧚 periodt.

ngl bestie, that's the whole page 😭 it's short but it ate. go forth and disable those other groups 💜👑

and that's a wrap! 🌈 this came to you from the good people at ./drivers/pinctrl/meson, dated October 2026, under the Kernel API Manual umbrella. mwah 💋 see u in the next group chat 🎀💖
