✨ ti_bandgap_build(9) ✨

okay so this one lives in the Kernel API Manual and it's basically the glow-up phase for a bandgap sensor — bestie, let's get into it 💅

---

🌸 NAME 🌸

ti_bandgap_build — parse the DT and set up a struct ti_bandgap

---

🎀 SYNOPSIS 🎀

struct ti_bandgap * ti_bandgap_build (struct platform_device *pdev );

---

🦋 ARGUMENTS 🦋

• pdev — pointer to the device struct platform_device. that's it, that's the whole input, she's low maintenance 💖

---

💫 DESCRIPTION 💫

so what this does is: it reads the device tree properties, and it does it according to the bandgap matching version — like, it checks which version it's dealing with first, no cap. 🔍

then, based on the bandgap version and whatever capabilities come with it, it builds a struct ti_bandgap out of the required DT entries. it's giving "custom-fit outfit made from your device tree" energy, honestly. main character struct construction 👑

---

⭐ RETURN ⭐

returns a valid bandgap structure if it worked (slay ✨). if it didn't work, it returns an ERR_PTR return value — and bestie, you must verify that with IS_ERR. like, do not skip the vibe check on this one, fr fr 🚨
