STRUCT TEGRA_PINCTRL_SOC_DATA(9)

💅 struct tegra_pinctrl_soc_data(9) — Kernel API Manual 🎀

okay bestie, welcome to the glow-up doc for struct tegra_pinctrl_soc_data — it's the config blueprint for the Tegra pin controller driver, and honestly? it's giving "quietly runs the whole show" energy 👑

✨ NAME ✨

struct tegra_pinctrl_soc_data — the Tegra pin controller driver configuration 🦋

🌸 SYNOPSIS 🌸

struct tegra_pinctrl_soc_data {
    unsigned ngpios;
    const char *gpio_compatible;
    const struct pinctrl_pin_desc *pins;
    unsigned npins;
    const char * const *functions;
    unsigned nfunctions;
    const struct tegra_pingroup *groups;
    unsigned ngroups;
    bool hsm_in_mux;
    bool schmitt_in_mux;
    bool drvtype_in_mux;
    bool sfsel_in_mux;
 };

like, look at her. every field accounted for, no notes 💖

🌈 Members 🌈

• ngpios — how many GPIO pins the pin controller HW actually touches. the headcount, basically 🧮
• gpio_compatible — the device-tree GPIO compatible string. her official government name ✨
• pins — an array describing all the pins the pin controller affects. ⚠️ and here's the rule, no cap: all pins which are also GPIOs must be listed first within the array, and be numbered identically to the GPIO controller's numbering. so like, order matters, bestie. don't be chaotic with it 🫶
• npins — the number of entries in pins. the count 🌸
• functions — an array describing all the mux functions the SoC supports. the whole menu 💅
• nfunctions — the number of entries in functions. menu length, fr fr 🔢
• groups — an array describing all the pin groups the pin SoC supports. squad goals, grouped up 👯
• ngroups — the number of entries in groups. how many squads 🌟
• hsm_in_mux — High-speed mode field. 🚨 only applicable to devices with one pin per group. read that twice if you need to 💀
• schmitt_in_mux — Schmitt trigger field. 😭 same deal: only applicable to devices with one pin per group.
• drvtype_in_mux — Drivetype field. 🔥 again — only applicable to devices with one pin per group.
• sfsel_in_mux — Special function selection field. ⭐ and yep, only applicable to devices with one pin per group. the four *_in_mux booleans are all matching, it's giving coordinated outfit 🎀

lowkey important: those last four are only for devices with one pin per group. not a vibe check you get to skip 💜
