STRUCT ADF4350_PLATFORM_DATA(9)

💅 struct adf4350_platform_data(9) — Kernel API Manual 🎀

okay bestie, so this is a page from the Kernel API Manual and it's all about struct adf4350_platform_data — the little vibe-check bundle that tells the ADF4350 driver what your hardware actually looks like. platform specific information, that's the whole gig. no cap, it's short and it's iconic. ✨

🌸 NAME 🌸

struct adf4350_platform_data — platform specific information. that's it, that's the name, she's giving exactly what it says on the tin 🫶

---

✨ SYNOPSIS ✨

here's the whole struct, character for character, do not touch, do not "fix", she's perfect:

struct adf4350_platform_data {
    char name[32];
    unsigned long           clkin;
    unsigned long           channel_spacing;
    unsigned long long      power_up_frequency;
    unsigned short          ref_div_factor;
    bool ref_doubler_en;
    bool ref_div2_en;
    unsigned r2_user_settings;
    unsigned r3_user_settings;
    unsigned r4_user_settings;
 };

💖 Members 💖

okay so let's go through every single field, no skipping, we're doing the full tour 🧚

• name — Optional device name. cute little label, entirely optional, she can stay nameless if she wants 💅
• clkin — REFin frequency in Hz. that's your reference input frequency, in Hz, periodt.
• channel_spacing — Channel spacing in Hz (influences MODULUS). yes it literally influences MODULUS, that's the note, we're not editing it 🙈
• power_up_frequency — Optional, If set in Hz the PLL tunes to the desired frequency on probe. so if you set it, the PLL just slides right into that frequency on probe. lowkey convenient.
• ref_div_factor — Optional, if set the driver skips dynamic calculation and uses this default value instead. you're basically telling the driver "don't do the math, bestie, I already did it" 🔥
• ref_doubler_en — Enables reference doubler.
• ref_div2_en — Enables reference divider.
• r2_user_settings — User defined settings for ADF4350/1 REGISTER_2. your house, your rules, your register ✨
• r3_user_settings — User defined settings for ADF4350/1 REGISTER_3.
• r4_user_settings — User defined settings for ADF4350/1 REGISTER_4.

fr fr, three separate registers of user-defined settings — REGISTER_2, REGISTER_3, REGISTER_4 — and the driver hands them straight to you. iykyk 👑

that's the whole page bestie, every field, every Hz, every REGISTER. this one's from ./include/linux/iio/frequency, dated October 2026, filed under struct adf43...latform_data(9) — slay, 10/10, no notes 🌈💖🌸
