💅 aspeed_g6_sig_expr_set — like, the whole vibe

okay so bestie, real talk: this is a page from the Kernel API Manual, and it's all about aspeed_g6_sig_expr_set. Yes the name is a mouthful, no we are not shortening it, it's iconic and we respect it. 🎀

---

✨ NAME ✨

aspeed_g6_sig_expr_set — configures a pin's signal by applying an expression's descriptor state, for all the descriptors in that expression. That's it, that's the whole job. She's focused, she's efficient, she slays. 💅

---

🦋 SYNOPSIS 🦋

int aspeed_g6_sig_expr_set (struct aspeed_pinmux_data *ctx , const
       struct aspeed_sig_expr *expr , bool enable );

Like, three things go in, an int comes out. Simple as. ✨

---

🔥 ARGUMENTS 🔥

• ctx — the pinmux context. She's the main character of the story, holding all the state together. 👑
• expr — the expression that's associated with the function whose signal you're about to configure. Basically the little permission slip for the pin. 🎫
• enable — a bool, and it's giving very binary queen energy:
  • true → enable a function's signal through a pin's signal expression ✅
  • false → disable the function's signal ❌

no in-between, no "maybe", no "let's see how it goes". periodt. 🫶

---

🌈 RETURN 🌈

• 0 — the expression is configured exactly as you requested. a win, a slay, an ate. 💖
• a negative error code — otherwise. 😭 that's it, that's the whole deal, no extra lore here.

---

🌸 SEE ALSO 🌸

• the Kernel file ./drivers/pinctrl/aspeed/pinctrl-aspeed-g6.c — go read the source, iykyk, it's right there. 📖✨

ngl bestie, this one's short but she's mighty — every descriptor in the expression gets the state applied, not just one, so don't come for her for being "too much". she's thorough. 🧚
