spi_get_gpio_descs(9)

👑 NAME

spi_get_gpio_descs — the little function that goes and grabs the chip select GPIOs for the controller, bestie 💅

Oh and hey, quick vibe check before we dive in: this page lives in the Kernel API Manual (yes, the actual kernel, the big one), so you know it's giving serious main character energy 🫶

✨ SYNOPSIS

int spi_get_gpio_descs(struct spi_controller *ctlr);

🎀 ARGUMENTS

• ctlr — the SPI controller you want to grab those GPIO descriptors for 💖 like, hand it the controller, it handles the chip selects. Periodt.
