STRUCT SCMI_PINCTRL_PROTO_OPS(9)

💅 NAME

struct scmi_pinctrl_proto_ops — bestie, this is literally the struct that holds all the operations the SCMI Pinctrl Protocol gives you ✨

🦋 SYNOPSIS

struct scmi_pinctrl_proto_ops {
    int (*count_get)(const struct scmi_protocol_handle *ph, enum scmi_pinctrl_selector_type type);
    int (*name_get)(const struct scmi_protocol_handle *ph, u32 selector, enum scmi_pinctrl_selector_type type, const char **name);
    int (*group_pins_get)(const struct scmi_protocol_handle *ph, u32 selector, const unsigned int **pins, unsigned int *nr_pins);
    int (*function_groups_get)(const struct scmi_protocol_handle *ph, u32 selector, unsigned int *nr_groups, const unsigned int **groups);
    int (*mux_set)(const struct scmi_protocol_handle *ph, u32 selector, u32 group);
    int (*settings_get_one)(const struct scmi_protocol_handle *ph, u32 selector, enum scmi_pinctrl_selector_type type, enum scmi_pinctrl_conf_type config_type, u32 *config_value);
    int (*settings_get_all)(const struct scmi_protocol_handle *ph, u32 selector, enum scmi_pinctrl_selector_type type, unsigned int *nr_configs, enum scmi_pinctrl_conf_type *config_types, u32 *config_values);
    int (*settings_conf)(const struct scmi_protocol_handle *ph, u32 selector, enum scmi_pinctrl_selector_type type, unsigned int nr_configs, enum scmi_pinctrl_conf_type *config_type, u32 *config_value);
    int (*pin_request)(const struct scmi_protocol_handle *ph, u32 pin);
    int (*pin_free)(const struct scmi_protocol_handle *ph, u32 pin);
 };

🎀 MEMBERS

okay so here's the whole friend group, one function pointer at a time 🫶

• count_get — hands you back the count of the registered elements in the given type. very "how many of y'all are there" energy 💖
• name_get — returns the name by index of the given type. it's giving "who are you again" but make it polite ✨
• group_pins_get — returns the set of pins assigned to the specified group. the whole squad, assembled 😭
• function_groups_get — returns the set of groups assigned to the specified function. like, which groups are matching the vibes of this function? 💅
• mux_set — sets the muxing function for groups of pins. muxing = the main character switch-up 🔥
• settings_get_one — returns one configuration parameter for the pin or group specified by config_type. just the one, no extra 🍓
• settings_get_all — returns all the configuration parameters for the pin or group. the full drop, no cap 👑
• settings_conf — sets the configuration parameter for the pin or group. this is the "actually do the thing" one 🌸
• pin_request — aquire the pin before selecting the mux setting. (yes, that's "aquire" — spelling stays exactly as the source says it, iykyk 🙈)
• pin_free — frees the pin, acquired by request_pin call. bye bestie, you're released 💜
