STRUCT SPMI_PMIC_ARB(9)

🦋 struct spmi_pmic_arb(9) 🦋

okay bestie, welcome to the Kernel API Manual — this is the page for struct spmi_pmic_arb, literally the SPMI PMIC Arbiter object ✨ she's the main character of the arbiter world, no cap.

🌸 NAME 🌸

struct spmi_pmic_arb — the SPMI PMIC Arbiter object 💅 that's it, that's the name, she's iconic

✨ SYNOPSIS ✨

struct spmi_pmic_arb {
    void __iomem            *rd_base;
    void __iomem            *wr_base;
    void __iomem            *core;
    resource_size_t core_size;
    void __iomem            *apid_map;
    u8 channel;
    u8 ee;
    const struct pmic_arb_ver_ops *ver_ops;
    int max_periphs;
    struct spmi_pmic_arb_bus *buses[PMIC_ARB_MAX_BUSES];
    int buses_available;
 };

like, look at her. she's got range 🫶

🎀 Members 🎀

• rd_base — the read register base, and where it lives is giving version dependent ngl: on v1 it's the "core" register base, on v2 it's the "observer" register base off DT 🌈
• wr_base — the write register base, same situation fr: on v1 it's the "core" register base, on v2 it's the "chnls" register base off DT 💜
• core — the core register base, but like… for v2 and above only (see above, bestie, I literally just told you 👀)
• core_size — the size of that core register base ⭐
• apid_map — on v8, the APID mapping table register base 🔥
• channel — the execution environment channel to use for accesses, iykyk
• ee — the current Execution Environment 💫
• ver_ops — the version dependent operations, so she knows how to act depending on what version she's dealing with 🧚
• max_periphs — Number of elements in apid_data[] 🍓
• buses — per arbiter buses instances, like one for each, okay 💖
• buses_available — number of buses registered 👑
