✨ kempld_write32(9) ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally all about kempld_write32 — the little function that writes a 32-bit register. it's giving "one job, does it well" energy 💅

---

🌸 NAME 🌸

kempld_write32 — write 32 bit register 🫶

---

🎀 SYNOPSIS 🎀

void kempld_write32 (struct kempld_device_data *pld , u8 index , u32 data );

that's the whole signature, no cap. it returns void, so don't be out here expecting a return value, bestie 😭

---

🦋 ARGUMENTS 🦋

• pld — the kempld_device_data structure that describes the PLD 👑
• index — the register index on the chip 🔥
• data — the new register value ⭐

---

💖 DESCRIPTION 💖

okay so here's the thing, and it's lowkey important: kempld_get_mutex must be called prior to calling this function. like, before. not after. not during. before. 🙈

fr fr, lock the mutex first or you're gonna have a bad time 😭
