STRUCT PMIC_ARB_VER_OPS(9)

🌸 struct pmic_arb_ver_ops(9) 🌸

okay so this is the Kernel API Manual page for struct pmic_arb_ver_ops, and bestie, it is exactly what it sounds like: the little table of function pointers that lets this driver be like "oh you're on v1? bet. oh you're on v2? say less" 💅 version-dependent functionality, living its best polymorphic life.

✨ NAME ✨

struct pmic_arb_ver_ops — version dependent functionality.

🦋 SYNOPSIS 🦋

struct pmic_arb_ver_ops {
    const char *ver_str;
    int (*get_core_resources)(struct platform_device *pdev, void __iomem
*core);
    int (*get_bus_resources)(struct platform_device *pdev, struct
device_node *node, struct spmi_pmic_arb_bus *bus);
    int (*init_apid)(struct spmi_pmic_arb_bus *bus, int index);
    int (*ppid_to_apid)(struct spmi_pmic_arb_bus *bus, u16 ppid);
    int (*offset)(struct spmi_pmic_arb_bus *bus, u8 sid, u16 addr, enum
pmic_arb_channel ch_type);
    u32 (*fmt_cmd)(u8 opc, u8 sid, u16 addr, u8 bc);
    int (*non_data_cmd)(struct spmi_controller *ctrl, u8 opc, u8 sid);
    void __iomem *(*owner_acc_status)(struct spmi_pmic_arb_bus *bus, u8
m, u16 n);
    void __iomem *(*acc_enable)(struct spmi_pmic_arb_bus *bus, u16 n);
    void __iomem *(*irq_status)(struct spmi_pmic_arb_bus *bus, u16 n);
    void __iomem *(*irq_clear)(struct spmi_pmic_arb_bus *bus, u16 n);
    u32 (*apid_map_offset)(u16 n);
    void __iomem *(*apid_owner)(struct spmi_pmic_arb_bus *bus, u16 n);
    int (*check_chnl_status)(struct spmi_controller *ctrl, u32 status,
u8 sid, u16 addr, u32 offset);
 };

like, look at all those function pointers 🫶 she's basically a vtable and she knows it.

👑 Members 👑

okay, one by one, no skipping, we don't do that here:

• ver_str — the version string. her name tag at the party 🎀
• get_core_resources — initializes the core, observer and channels
• get_bus_resources — requests per-SPMI bus register resources
• init_apid — finds the apid base and count
• ppid_to_apid — finds the apid for a given ppid.
• offset — on v1 it's the offset of per-ee channel. on v2 it's the offset of per-ee and per-ppid channel. glow-up fr 💅
• fmt_cmd — formats a GENI/SPMI command.
• non_data_cmd — on v1 it issues an spmi non-data command. on v2, no HW support, so it returns -EOPNOTSUPP. 😭 not her getting ghosted by the hardware
• owner_acc_status — on v1, address of PMIC_ARB_SPMI_PIC_OWNERm_ACC_STATUSn; on v2, address of SPMI_PIC_OWNERm_ACC_STATUSn.
• acc_enable — on v1, address of PMIC_ARB_SPMI_PIC_ACC_ENABLEn; on v2, address of SPMI_PIC_ACC_ENABLEn.
• irq_status — on v1, address of PMIC_ARB_SPMI_PIC_IRQ_STATUSn; on v2, address of SPMI_PIC_IRQ_STATUSn.
• irq_clear — on v1, address of PMIC_ARB_SPMI_PIC_IRQ_CLEARn; on v2, address of SPMI_PIC_IRQ_CLEARn.
• apid_map_offset — offset of PMIC_ARB_REG_CHNLn
• apid_owner — on v2 and later, address of SPMI_PERIPHn_2OWNER_TABLE_REG
• check_chnl_status — checks channel status and returns error code if any

heads up bestie: this page is literally just a struct + its member docs, so there's no extra lore hiding in here. what you see is what you get 💖

and that's the whole page!! brought to you by the source in ./drivers/spmi 💫 dated October 2026 ⭐ slay, go forth and support all the versions 🦋💜
