✨ stm32_adc_conf_scan_seq ✨

okay bestie, buckle up 💖 this one lives in the Kernel API Manual and it's literally the glow-up artist for your regular channels — it builds the scan sequence, no cap.

---

🌸 NAME 🌸

stm32_adc_conf_scan_seq — build regular channels scan sequence 🎀

---

🦋 SYNOPSIS 🦋

int stm32_adc_conf_scan_seq (struct iio_dev *indio_dev , const unsigned
long *scan_mask );

---

💅 ARGUMENTS 💅

• indio_dev — the IIO device, aka the main character of this whole operation 👑
• scan_mask — the channels that are gonna get converted, hand-picked by you 🫶

---

🔥 DESCRIPTION 🔥

Conversion sequence — here's the tea 🍓: first it applies the sampling time settings for all the channels. Every single one. Not a vibe check skipped.

Then it configures the ADC scan sequence based on whichever channels you selected in scan_mask ✨.

The way it does this: it adds channels to the SQR registers, going from scan_mask LSB to MSB (lowkey important order, don't come for me), and then it programs the sequence length. Periodt. 💀
