pcs_allocate_pin_table(9)

✨ pcs_allocate_pin_table(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — pcs_allocate_pin_table(9) if we're being formal, which we are 💅

---

🌸 NAME 🌸

pcs_allocate_pin_table — adds all the pins for the pinctrl driver ✨

like, all of them. every single pin. she's a completionist, no cap 🎀

---

🦋 SYNOPSIS 🦋

int pcs_allocate_pin_table (struct pcs_device *pcs );

---

💜 ARGUMENTS 💜

• pcs — pcs driver instance. that's it, that's the whole argument list. one (1) friend, and she's the driver instance 🫶

---

🔥 DESCRIPTION 🔥

so here's the vibe: if things go sideways — and you know things go sideways — the resources get freed in pcs_free_resources. cleanup is handled, she's got a whole recovery arc, we love a responsible queen 😭💖

now, the main character note 👑: if your hardware needs holes in the address space, the move is to just set up multiple driver instances. like, don't try to make one instance do gymnastics — multiple instances, multiple problems solved. periodt.

real talk though: this page does not spell out what happens beyond that, so don't go inventing behaviour, bestie — that's all the manual gives us 💅
