pinctrl_provide_dummies(9)
πΈ pinctrl_provide_dummies β NAME πΈ
okay so this is pinctrl_provide_dummies, bestie β it's the little function that tells the pinctrl core "hey, dummy state support? yes please" β¨ and it lives in the Kernel API Manual, which is literally the group chat of kernel docs π
β¨ SYNOPSIS β¨
void pinctrl_provide_dummies (void );
π ARGUMENTS π
voidβ no arguments. that's it. that's the whole vibe. nothing to pass, nothing to configure, she takes zero input and serves pure energy π«Ά
π DESCRIPTION π
okay so here's the tea β β usually this function gets called by platforms that don't have pinctrl driver support, but that still run alongside some shared drivers which are out here using pinctrl APIs anyway π like imagine showing up to the party when you don't even have an invite, that's those shared drivers fr fr.
so after you call this function, the pinctrl core will return successfully and create a dummy state for the driver, so everything keeps going smoothly instead of absolutely falling apart πβ¨ it's giving "fake it till you make it" but make it kernel infrastructure, no cap π₯
lowkey iconic of the kernel to just... hand you a fake state so your driver doesn't crash. main character energy honestly π
