✨ ice_tspll_init(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one lives in section 9 and it's literally all about waking up the TSPLL. yes we're doing clock stuff today, buckle up 🎀

🌸 NAME 🌸

ice_tspll_init — initializes the TSPLL using the settings that came straight from firmware 🫶

⭐ SYNOPSIS ⭐

int ice_tspll_init (struct ice_hw *hw );

🦋 ARGUMENTS 🦋

• hw — a pointer to the HW structure 👑 that's it, that's the whole argument list, she's low maintenance

💅 DESCRIPTION 💅

So basically this function sets up the Clock Generation Unit of the E82X/E825 device ✨ like, it takes the config from firmware and makes the clock gen unit actually be a clock gen unit. main character energy fr fr 🕐👑

🔥 RETURN 🔥

• 0 — slay, it worked 💖 success
• other error codes — it's giving "failed to read/write/cfg CGU" 😭 so like, if reading, writing, or configuring the CGU didn't go through, you get a different error code back

ngl if you're not getting 0 back, something in the read/write/cfg pipeline said no 💀
