pinmux_generic_add_function(9)

🌸 NAME 🌸

pinmux_generic_add_function — adds a function group. That's literally the whole assignment, bestie: it adds a function group. This page is from the Kernel API Manual, and we're about to make it make sense. 💅

✨ SYNOPSIS ✨

int pinmux_generic_add_function (struct pinctrl_dev *pctldev , const
       char *name , const char * const *groups , const unsigned int ngroups ,
       void *data );

Okay so this is the incantation. It returns an int, and it takes five arguments. Copy the names exactly, no improvising, fr fr. 🫶

🎀 ARGUMENTS 🎀

• pctldev — pin controller device. It's the pin controller bestie in question.
• name — name of the function. Yes, the function's name. Iconic.
• groups — array of pin groups. Not one group, an array of them.
• ngroups — number of pin groups. This is the count for that groups array.
• data — pin controller driver specific data. The driver's own little payload.
