💅 stm32_dfsdm_stop_dfsdm(9)

okay bestie, so this is a page straight out of the Kernel API Manual — we're talking kernel-level, driver-adjacent, extremely niche and honestly kind of iconic 🎀

✨ NAME ✨

stm32_dfsdm_stop_dfsdm — literally just stops the global DFSDM interface. that's the whole gig. no cap 💅

---

🌸 SYNOPSIS 🌸

int stm32_dfsdm_stop_dfsdm (struct stm32_dfsdm *dfsdm );

that's it. one arg, returns an int, go off 👑

---

🦋 ARGUMENTS 🦋

• dfsdm — the handle you use to retrieve the dfsdm context. like, it's your little backstage pass to the whole situation 🎟️

---

💖 DESCRIPTION 💖

so what it does is: disable the interface if n_active_ch is null. that's the vibe. no channels active? interface gets shut down, periodt 🫶

fr fr read that condition carefully — the disable only happens when n_active_ch is null. don't be out here assuming it always nukes the interface 💀

• the kernel file ./drivers/iio/adc/stm32-dfsdm-core.c — that's where the magic lives, go look 👀
• struct stm32_dfsdm_dev_data(9)
• stm32_dfsdm_start_dfsdm(9) — the inverse icon, the "we're so back" to this one's "it's over" ✨
