STRUCT PISOSR_GPIO(9)

🎀 struct pisosr_gpio(9) 🎀

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for struct pisosr_gpio, and no cap, it's a little cutie. 💖

💅 NAME 💅

struct pisosr_gpio — literally the GPIO driver data. that's it, that's the vibe. 🦋

✨ SYNOPSIS ✨

struct pisosr_gpio {
    struct gpio_chip chip;
    struct spi_device *spi;
    u8 *buffer;
    size_t buffer_size;
    struct gpio_desc *load_gpio;
    struct mutex lock;
 };

ngl, look at her. six fields, all iconic in their own way. 👑

🌸 Members 🌸

• chip — the GPIO controller chip itself. main character energy fr. 🫶
• spi — a pointer to the SPI device. iykyk. 🌈
• buffer — the buffer for device reads. she holds the data, that's her job. 💜
• buffer_size — the size of that buffer. because buffer without buffer_size is giving "unfinished sentence". 😭
• load_gpio — the GPIO pin used to load input into the device. lowkey the most important pin here. 🔥
• lock — a mutex that protects read sequences. do not skip the lock, bestie, that's how you get chaos. 💀

⭐ SEE ALSO ⭐

• Kernel file ./drivers/gpio/gpio-pisosr.c — go read it, it's right there. 📖

and that's the whole page, periodt. 💅
