STRUCT AD5791_PLATFORM_DATA(9)

💖 struct ad5791_platform_data(9) 💖

okay bestie, so this is a page from the Kernel API Manual — yes, that Kernel API Manual — and it's all about struct ad5791_platform_data, the little bundle of platform specific information you hand over so the AD5791 driver knows what's up. she's small, she's tidy, she's giving "three fields and a dream" energy ✨

🌸 NAME 🌸

struct ad5791_platform_data — platform specific information

like, literally just the platform-specific deets. that's the whole vibe check. 🫶

---

🦋 SYNOPSIS 🦋

struct ad5791_platform_data {
    u16 vref_pos_mv;
    u16 vref_neg_mv;
    bool use_rbuf_gain2;
 };

three members, no cap. here's the tea on each one 👇

---

🎀 Members 🎀

• vref_pos_mv — Vdd Positive Analog Supply Volatge (mV). yeah, the source spells it "Volatge" 😭 — we're keeping it, it's iconic, we don't gatekeep typos here. it's a u16 and it's in millivolts, periodt.
• vref_neg_mv — Vdd Negative Analog Supply Volatge (mV). the negative twin 💜 same deal: u16, millivolts, matching energy.
• use_rbuf_gain2 — ext. amplifier connected in gain of two configuration. it's a bool, so it's a yes/no slay: flip it when your external amp is wired up in that gain-of-two setup. 🔥

ngl, all three of these are exactly what the driver gets handed at probe time — nothing more, nothing less. don't go inventing fields, bestie, she has a strict guest list 💅

🌈 SEE ALSO 🌈

• Kernel file ./include/linux/iio/dac/ad5791.h — go read the header, it's the main character of this whole situation 👑

and that's the whole page, bestie!! shipped from ./include/linux/iio/dac, dated October 2026, and yes the page itself is titled struct ad5791_platform_data(9) — she said "put my name on it" and honestly? deserved. 🎀🦋💖✨🍓
