Okay bestie, welcome to the Kernel API Manual entry for acpi_lpss_save_ctx(9) — it's lowkey giving “save the private registers of an LPSS device” energy, and we're gonna understand it together. 🫶✨

🎀 NAME 🎀

acpi_lpss_save_ctx — Save the private registers of LPSS device 💅

---

✨ SYNOPSIS ✨

void acpi_lpss_save_ctx (struct device *dev , struct lpss_private_data
       *pdata );

---

🫶 ARGUMENTS 🫶

• dev — the LPSS device 💻
• pdata — pointer to the private data of the LPSS device 🎀

---

💖 DESCRIPTION 💖

So here's the vibe: most LPSS devices have private registers, and those registers may loose their context when the device is powered down. 😭 Yes, “loose” — that's literally the spelling in the original, bestie, we're not fixing it, we're respecting the icon.

acpi_lpss_save_ctx saves those registers into the prv_reg_ctx array. That's it. That's the whole main-character job. 🔥👑

No cap: this is the save-side bestie. The restore-side one is waiting in SEE ALSO, iykyk. 🦋
