✨ ks8851_wrreg16 — 16-bit register write moment 💅

okay so this is a page from the Kernel API Manual, bestie — yep, the actual kernel docs, and this one's about a tiny-but-iconic little function called ks8851_wrreg16. she's not flashy, she's not huge, she's just out here writing 16-bit register values to a chip and honestly? we respect her for it 🫶

---

✨ NAME ✨

ks8851_wrreg16 — literally just: write a 16-bit register value to the chip 🎀

---

🌸 SYNOPSIS 🌸

void ks8851_wrreg16 (struct ks8851_net *ks , unsigned int reg , unsigned
int val );

that's the whole vibe. no return value, no drama, just vibes and a write 💜

---

🦋 ARGUMENTS 🦋

• ks — the chip state, aka where all the chip's little secrets live. this is the main character of the argument list ngl 👑
• reg — the register address, i.e. which little slot in the chip we're talking to 💅
• val — the value you want to write, i.e. the actual message you're sending 🍓

---

💖 DESCRIPTION 💖

so basically: you issue a write, and val gets put into the register specified by reg. that's it. that's the function. she eats and leaves no crumbs 🔥

like, no cap, it really is that simple — reg points at the register, val is the 16-bit value going in, and the chip is updated accordingly. periodt ✨
