STRUCT TI_ABB(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 struct ti_abb 🦋

okay bestie, so this page is all about the struct ti_abb — it's the ABB instance data 💅 and it lives in the Kernel API Manual (yes, the kernel, we're in our systems-programming era fr fr). let's get into it ✨

✨ NAME ✨

struct ti_abb — literally just the ABB instance data, that's the whole vibe 🎀

🧚 SYNOPSIS 🧚

here's the whole struct, no cap, copy it exactly:

struct ti_abb {
    struct regulator_desc rdesc;
    struct clk *clk;
    void __iomem *base;
    void __iomem *setup_reg;
    void __iomem *control_reg;
    void __iomem *int_base;
    void __iomem *efuse_base;
    void __iomem *ldo_base;
    const struct ti_abb_reg *regs;
    u32 txdone_mask;
    u32 ldovbb_override_mask;
    u32 ldovbb_vset_mask;
    struct ti_abb_info *info;
    int current_info_idx;
    u32 settling_time;
};

💅 Members 💅

okay so this is the main character section, each member gets its own little moment 👑

  • rdesc — the regulator descriptor. it's giving official-documentation energy 💖
  • clk — the clock (usually sysclk) that's supplying the ABB block. keeping the lights on, slay ⚡
  • base — base address of the ABB block. it's the home base, iykyk 🏠
  • setup_reg — the setup register of the ABB block ✨
  • control_reg — the control register of the ABB block. controls things, lowkey its whole job 🎮
  • int_base — interrupt register base address. interruptions? rude. but necessary 💀
  • efuse_base — (optional!) efuse base address for ABB modes. icon behavior, only shows up when it wants 🌈
  • ldo_base — (optional bb) LDOVBB vset override base address 🦋
  • regs — pointer to struct ti_abb_reg for the ABB block. pointing at its own lore 🔥
  • txdone_mask — the mask on int_base for the tranxdone interrupt 🎀
  • ldovbb_override_mask — mask to ldo_base for overriding the default LDO VBB vset with the value from efuse. like a glow-up for your vset, no cap 💜
  • ldovbb_vset_mask — mask to ldo_base for providing the VSET override ✨
  • info — array to per voltage ABB configuration. yes "per voltage", plural voltages, multi-tasking queen 👑
  • current_info_idx — the current index into info. it's keeping track, the way it stays organized is honestly goals 📋
  • settling_time — SoC specific settling time for LDO VBB. everything needs a minute to settle, respect it 🫶

bestie this whole thing lives under ./drivers/regulator in the kernel tree, dated October 2026, and it came from the Kernel API Manual — so when you cite it, cite it with your whole chest 💖 periodt 🫶✨
