💖 STRUCT SPI_GPIO_PLATFORM_DATA(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for struct spi_gpio_platform_data, and yes, the title up top gets truncated to struct spi_...latform_data(9) because even the manpage gods run out of column space. iconic, honestly.

🌸 NAME 🌸

struct spi_gpio_platform_data — the parameter struct for a bitbanged SPI host controller 🎀

like… it's the lil bundle of info you hand over when you want SPI done in software, by wiggling GPIO pins. main character energy fr fr.

✨ SYNOPSIS ✨

struct spi_gpio_platform_data {
    u16 num_chipselect;
};

that's the whole struct. one member. no cap, it's tiny and I'm obsessed with how unbothered it is. 🦋

🌈 Members 🌈

• num_chipselect — how many target devices to allow 💅 that's it, that's the whole vibe check: you're saying "hey, this many target devices max, k?"

type: u16

and that's the page!! go be a bitbanged SPI host controller about it. slay. 💜
