STRUCT BRCMFMAC_PLATFORM_DATA(9)

💅 struct brcmfmac_platform_data — BRCMFMAC specific platform data ✨

okay so bestie, welcome to the struct brcmfmac_platform_data(9) page from the Kernel API Manual 🎀 this is the little bundle of platform-specific hooks that the BRCMFMAC driver picks up, and honestly? she's giving "small struct, big responsibilities" energy 👑

---

🌸 SYNOPSIS 🌸

struct brcmfmac_platform_data {
    void (*power_on)(void);
    void (*power_off)(void);
    char *fw_alternative_path;
    int device_count;
    struct brcmfmac_pd_device devices[];
 };

no cap, that's the whole shape of her 🫶

✨ Members ✨

🧚 power_on

so this function pointer gets called by the brcmfmac driver when the module gets loaded, periodt 💫 and like, it's particularly useful for low power devices — the platform specific routine may for example decide to power up the complete device. main character move tbh 🔥

and if there's genuinely no use-case for this function? then provide NULL. that's it, that's the vibe 💅

🎀 power_off

this one gets called by the brcmfmac when the module gets unloaded 🦋 at that point the devices can be powered down or otherwise be reset. so listen — if an actual power_off is not supported but reset is supported by the devices, then reset the devices when this function gets called, okay? iykyk 😌

same deal as her sister above: particularly useful for low power devices, and if there is no use-case for this function then provide NULL 🙈

💜 fw_alternative_path

she's in the struct, bestie — listed right there in the synopsis and she counts 💜 (char *, for the record).

⭐ device_count

int device_count — also a member, also present, also not skipped, because we do not skip members on this page 🫶

🌈 devices[]

struct brcmfmac_pd_device devices[] — the flexible array member at the end of the struct, exactly as declared ✨

fair warning bestie: this page spells out the deets for power_on and power_off, and the other members just sit there in the struct definition. no invented lore, no made-up behaviour, we don't do that here 💀
