✨ lmk04832_check_vco_ranges 💅

okay so bestie, welcome to the Kernel API Manual — this one's a little function with main character energy, and it lives in lmk04832_check_vco_ranges(9) 🎀

---

💖 NAME

lmk04832_check_vco_ranges — literally checks whether the VCO frequency you're asking for actually fits inside the VCO ranges 🌸

---

🦋 SYNOPSIS

int lmk04832_check_vco_ranges (struct lmk04832 *lmk , unsigned long rate );

---

🍓 ARGUMENTS

• lmk — your reference to the lmk device, like your plus-one at the function call 🫶
• rate — the desired output rate for the VCO, i.e. the vibe you're going for ✨

---

👑 DESCRIPTION

okay so the LMK04832 has 2 internal VCO, and each one has its own independent operating ranges — no cap, they don't share 💀

so what you do is: use the device_info structure to figure out which VCO to use based on rate. that's the whole assignment. iconic, honestly 🌈

---

🔥 RETURN

returns the VCO_MUX value — or a negative errno if things did not, in fact, slay 😭
