STRUCT PMIC_GPIO_PAD(9)

💅 NAME 💅

struct pmic_gpio_pad — the little guy that keeps your current GPIO settings, bestie 💖

✨ SYNOPSIS ✨

okay so here's the whole struct, no cap, every field exactly as it lives:

struct pmic_gpio_pad {
    u16 base;
    bool is_enabled;
    bool out_value;
    bool have_buffer;
    bool output_enabled;
    bool input_enabled;
    bool analog_pass;
    bool lv_mv_type;
    unsigned int    num_sources;
    unsigned int    power_source;
    unsigned int    buffer_type;
    unsigned int    pullup;
    unsigned int    strength;
    unsigned int    function;
    unsigned int    atest;
    unsigned int    dtest_buffer;
 };

like… she's giving "small struct, big responsibilities" and honestly? iconic. 👑

🎀 Members 🎀

here's the vibe check on every single field, one by one, no skipping, we don't do that here 🫶

• base — the address base in the SPMI device. like, where she lives. 🏠
• is_enabled — gets set to false when the GPIO should be put in high Z state. so false = "girl's not driving anything rn", ok?? 😭
• out_value — the cached pin output value. she remembers what you last told her. 🧠
• have_buffer — set to true if the GPIO output could be configured in push-pull, open-drain or open-source mode. if this is false, don't even ask her to pick a buffer mode, it's not happening 🙈
• output_enabled — set to true if GPIO output logic is enabled. 🔥
• input_enabled — set to true if GPIO input buffer logic is enabled. ✨
• analog_pass — set to true if the GPIO is in analog-pass-through mode. letting it all flow through, main character energy tbh 🌊
• lv_mv_type — set to true if the GPIO subtype is GPIO_LV(0x10) or GPIO_MV(0x11). lowkey a little name-tag check 💅
• num_sources — number of power-sources supported by this GPIO. how many vibes she can plug into ⚡
• power_source — the current power-source used. which one she's running on rn 🔌
• buffer_type — push-pull, open-drain or open-source. the whole personality of the output 🦋
• pullup — constant current which flow trough GPIO output buffer. yes that's the original wording of the concept, we're keeping it, she pulls 🔥
• strength — No, Low, Medium, High. literally a slider, pick your fighter 💪
• function — see pmic_gpio_functions[]. she has a whole roster, go look 👀
• atest — the ATEST selection for GPIO analog-pass-through mode. 🧪
• dtest_buffer — the DTEST buffer selection for digital input mode. 🎯

friendly reminder bestie: is_enabled being false means high Z state — that's the "hands off, I'm not driving this" setting, not a bug, don't come for her 💀
