💅 si476x_core_stop(9) 💅

okay so bestie, this is a kernel API manual page, and we're about to get into the si476x_core_stop function — it's literally the chip power-down function, and it's giving "turn off the lights, the party's over" energy. no cap. 🫶

✨ SYNOPSIS ✨

int si476x_core_stop (struct si476x_core *core , bool soft );

like, that's the whole vibe right there. 💖

🎀 ARGUMENTS 🎀

  • core — Core device structure. this is, like, the main character struct you're working with. the core device. periodt. 👑
  • soft — When set, function sends a POWER_DOWN command instead of bringing reset line low. so like, if you set this to true, it's a soft power down (sending the POWER_DOWN command, very gentle, very demure 🎀). if not, it brings the reset line low the old-school way. either way, the chip goes night-night. 😴

🌸 DESCRIPTION 🌸

Power down the chip by performing following actions. literally just powering it down, bestie. here's the step-by-step:

  1. Disable IRQ or stop the polling worker. yep, gotta shut down the interrupt party first. no more interruptions, we're closed. 🙈
  2. Send the POWER_DOWN command if the power down is soft or bring reset line low if not. so like — soft power down? POWER_DOWN command. not soft? reset line goes low. either way, chip is donezo. 💀

The function returns zero in case of success or negative error code otherwise. so like, 0 means slay, negative means something went wrong. not me checking that return value every single time. 😭

🦋 SEE ALSO 🦋

Kernel file ./drivers/mfd/si476x-i2c.c — and like, literally all the sister functions, bestie. the whole friend group:

go read them. they're all iconic in their own way. 💜

⚠️ okay bestie, real talk — this function returns zero on success or a negative error code otherwise. don't forget to check it. iykyk. 🫶

💖 sign-off 💖

so like, this whole thing lives in ./drivers/mfd and it's from October 2026, and the manual page name is si476x_core_stop(9) — which, honestly, is the main character energy we deserve. go power down that chip, bestie. slay. ✨💅🌈
