STRUCT AD5755_PLATFORM_DATA(9)

✨ struct ad5755_platform_data — the AD5755 DAC driver's platform data ✨

okay so bestie, this is a page from the Kernel API Manual, and it's all about struct ad5755_platform_data — literally the platform data for the AD5755 DAC driver 🎀 ngl it's a whole little config bundle you hand to the driver so it knows how you wired everything up. Let's get into it 💅

---

🌸 NAME 🌸

struct ad5755_platform_data — AD5755 DAC driver platform data. That's it, that's the name, periodt ✨

---

💖 SYNOPSIS 💖

here's the whole shape of it, character for character, no cap:

struct ad5755_platform_data {
    bool ext_dc_dc_compenstation_resistor;
    enum ad5755_dc_dc_phase dc_dc_phase;
    enum ad5755_dc_dc_freq dc_dc_freq;
    enum ad5755_dc_dc_maxv dc_dc_maxv;
    struct {
      enum ad5755_mode mode;
      bool ext_current_sense_resistor;
      bool enable_voltage_overrange;
      struct {
        bool enable;
        enum ad5755_slew_rate rate;
        enum ad5755_slew_step_size step_size;
      } slew;
    } dac[4];
   };

like, look at that nested struct energy 😭 there's a dac[4] array in there with its own little slew struct living inside it. main character nesting fr fr 🦋

👑 Members 👑

okay so every single one of these, in order, no skipping:

• ext_dc_dc_compenstation_resistor — tells you whether an external DC-DC converter compensation register is used. (yes bestie, that spelling is exactly how it's written in the source — we do not fix it, we respect it 💀)
• dc_dc_phase — the DC-DC converter phase.
• dc_dc_freq — the DC-DC converter frequency.
• dc_dc_maxv — the DC-DC maximum allowed boost voltage.
• dac — the per DAC instance parameters 🎀 (there's four of them, remember the dac[4]?)
• dac.mode — the mode to be used for the DAC output.
• dac.ext_current_sense_resistor — whether an external current sense resistor is used.
• dac.enable_voltage_overrange — whether to enable 20% voltage output overrange. twenty percent, iconic ✨
• dac.slew.enable — whether to enable digital slew.
• dac.slew.rate — the slew rate of the digital slew. slay rate, honestly 🔥
• dac.slew.step_size — the slew step size of the digital slew.

and that's the whole page, you ate that 🫶💜 this was struct ad5755_platform_data(9) from the Kernel API Manual, dated October 2026, living its best life at ./drivers/iio/dac — mwah, go read the driver now, ily, bye 🌈⭐
