ab8500_fg_b..._hw_register(9)

💅 ab8500_fg_battok_init_hw_register — from the Kernel API Manual, bestie ✨

okay so this is a page straight out of the Kernel API Manual, and it's about one tiny little function living inside the AB8500 fuel gauge driver. Short page, but honestly? Iconic. Let's get into it 🫶

---

🌸 NAME 🌸

ab8500_fg_battok_init_hw_register — init battok levels 💖

That's it. That's the whole job. It sets up the battok levels, periodt.

---

✨ SYNOPSIS ✨

int ab8500_fg_battok_init_hw_register (struct ab8500_fg *di );

so it returns an int (iykyk, that's the classic "did it work or not" situation 👀) and it takes exactly one pointer. no cap.

---

🎀 ARGUMENTS 🎀

• di — pointer to the ab8500_fg structure. that's your one and only input, bestie. just a pointer to the ab8500_fg struct, living its main character life 🌟

🦋 SEE ALSO 🦋

okay this is the part where the page goes absolutely off. the source of all this is the kernel file:

./drivers/power/supply/ab8500_fg.c

lowkey a reminder: this page is only about init-ing the battok levels. everything else? go read its own page, bestie 🧚
