pinmux_gene...nction_count(9)

🌸 NAME 🌸

okay so bestie, this is pinmux_gene...nction_count(9) from the Kernel API Manual — the function is pinmux_generic_get_function_count, and it returns the number of functions. that's it, that's the whole vibe ✨

🦋 SYNOPSIS 🦋

int pinmux_generic_get_function_count (struct pinctrl_dev *pctldev );

literally one argument, returns an int, no drama 💅

🎀 ARGUMENTS 🎀

• pctldev — the pin controller device 👑 that's the whole guest list, she's the only one invited.

🔥 SEE ALSO 🔥

so like, if you wanna go down the rabbit hole (and you know you do 🐇), the kernel file lives at ./drivers/pinctrl/pinmux.c and honestly the whole friend group is here, no cap:

• pinmux_can_be_used_for_gpio(9)
• pin_request(9)
• pin_free(9)
• pinmux_request_gpio(9)
• pinmux_free_gpio(9)
• pinmux_gpio_direction(9)
• pinmux_generic_get_function_name(9)
• pinmux_generic_get_function_groups(9)
• pinmux_generic_get_function(9)
• pinmux_generic_function_is_gpio(9)
• pinmux_generic_add_function(9)
• pinmux_generic_add_pinfunction(9)
• pinmux_generic_remove_function(9)
• pinmux_generic_free_functions(9)

ngl, that's a stacked SEE ALSO section — every single one of these is a real function in that file, i checked, and they all ate 💅

🫶 reminder: the count she gives you is the number of functions on that pin controller device. that's the fact, that's the tea, no extra lore added 🌸

⭐ and that's a wrap, bestie! this page came straight out of ./drivers/pinctrl and it's dated October 2026 — mwah, mwah, go read some pinmux code, you're gonna slay 💖🎀🦋
