STRUCT SOPHGO_CFG_OPS(9)

✨ struct sophgo_cfg_ops(9) ✨

okay so bestie, we're in the Kernel API Manual today, and the star of the show is struct sophgo_cfg_ops — literally the pin configuration operations table. it's giving "the hookup board for pinctrl" energy and honestly? iconic. 🎀

---

🌸 NAME 🌸

struct sophgo_cfg_ops — pin configuration operations. that's it, that's the whole vibe. 💅

---

✨ SYNOPSIS ✨

struct sophgo_cfg_ops {
    int (*pctrl_init)(struct platform_device *pdev, struct sophgo_pinctrl *pctrl);
    int (*verify_pinmux_config)(const struct sophgo_pin_mux_config *config);
    int (*verify_pin_group)(const struct sophgo_pin_mux_config *pinmuxs, unsigned int npins);
    int (*dt_node_to_map_post)(struct device_node *cur, struct sophgo_pinctrl *pctrl, struct sophgo_pin_mux_config *pinmuxs, unsigned int npins);
    int (*compute_pinconf_config)(struct sophgo_pinctrl *pctrl, const struct sophgo_pin *sp, unsigned long *configs, unsigned int num_configs, u32 *value, u32 *mask);
    int (*set_pinconf_config)(struct sophgo_pinctrl *pctrl, const struct sophgo_pin *sp, u32 value, u32 mask);
    void (*set_pinmux_config)(struct sophgo_pinctrl *pctrl, const struct sophgo_pin *sp, u32 config);
 };

like, look at her. seven function pointers, all slaying in their own lane. 🦋

okay let's meet the cast, one by one, no skips, we're doing all seven:

• pctrl_init — the soc specific init callback. every good story starts with an init, periodt. 🌱
• verify_pinmux_config — verifies the pinmux config for a pin. just one little pin getting its vibe check. 🔍
• verify_pin_group — verifies the whole pinmux group. now the entire friend group is under review, ngl. 👯
• dt_node_to_map_post — post init for the pinmux config map. the afterparty of the device tree mapping, lowkey essential. 🎉
• compute_pinconf_config — computes the pinconf config. math but make it pads. 🧮
• set_pinconf_config — sets the pinconf config, and heads up bestie: the caller holds lock. so like, don't just walk in and start touching things, the lock is held. 💀
• set_pinmux_config — sets the mux config, and again, for the people in the back: the caller holds lock. same rule, no cap. 🔒

• Kernel file ./drivers/pinctrl/sophgo/pinctrl-sophgo.h
• struct sophgo_vddio_cfg_ops(9) — her sibling, go say hi 🫶

fr fr bestie, go read the header file before you go poking at these pointers. the lock thing is not a drill. 💀✨

and that's the page!! 🎀 this whole thing lives over in ./drivers/pinctrl/sophgo, dated October 2026, and it's for struct sophgo_cfg_ops(9) — mwah, go forth and configure pins responsibly, ily 💖🔥
