ti_bandgap_writel(9)

✨ ti_bandgap_writel(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, that manual — and today's main character is ti_bandgap_writel. it's short, it's sweet, it's giving "small but essential," and honestly? we love her for it. 💅

---

🌸 NAME 🌸

ti_bandgap_writel — a simple little write helper function, no cap. that's literally the whole job description and she's thriving.

---

🎀 SYNOPSIS 🎀

void ti_bandgap_writel (struct ti_bandgap *bgp , u32 val , u32 reg );

that's it. that's the whole signature. three args, void return, zero drama. ✨

---

💖 ARGUMENTS 💖

• bgp — pointer to the ti_bandgap structure, aka the whole vibe container 🫶
• val — the desired register value that you want written, like the message you're about to send 📩
• reg — the desired register (that's the offset, iykyk) that's getting written to 🎯

---

🦋 DESCRIPTION 🦋

so what does she actually do? she's the helper function for writing bandgap registers — and the way she does it is by using the io remapped area. that's the whole flex. literally it. 😌

think of her as the group-chat admin who just quietly makes sure your message lands in the right place. no extra steps, no attitude, just a register write through the remapped io space. iconic behaviour, honestly. 👑

💀 heads up bestie: the manpage gives you exactly this much and no more — it doesn't spell out any extra behaviour, so don't go inventing any. we stan a page that knows its limits.

and that's the page, bestie!! 💖 this one came from the source ./drivers/thermal/ti-soc-thermal — which is also the title-ish bit at the bottom of the original, so yeah — dated October 2026, all official and everything. go write some registers. slay. 🎀✨🦋
