• configs — Configuration to set. the actual configs, plural, living in an unsigned long *.
• num_configs — Number of configurations. how many of those configs you're handing over. very "tell me how many are coming to the party" of her 💖

🧚 and that's the page!! brought to you by the <rainbow>Kernel API Manual</rainbow>, from ./drivers/pinctrl, dated October 2026, and yes the footer still says zynqmp_pinconf_group_set(9) because she's the main character and she's in the title and the footer. obsessed. bye bestie, go set some group configs 💅✨🍓
