struct ws16c48_gpio(9)

okay bestie, this is the Kernel API Manual page for struct ws16c48_gpio 💅 it's the private data structure for a GPIO device, and we are going to read every single field together, no skips, fr fr.

🎀 NAME 🎀

struct ws16c48_gpio — GPIO device private data structure

✨ SYNOPSIS ✨

struct ws16c48_gpio {
    struct regmap *map;
    raw_spinlock_t lock;
    u8 irq_mask[WS16C48_NUM_IRQS / WS16C48_NGPIO_PER_REG];
};

• map — regmap for the device. it's the device's regmap, periodt.
• lock — synchronization lock to prevent I/O race conditions. it's giving "wait your turn bestie" so the I/O doesn't get messy.
• irq_mask — I/O bits affected by interrupts. that's the mask for the I/O bits the interrupts are touching.

🌈 SEE ALSO 🌈

• Kernel file ./drivers/gpio/gpio-ws16c48.c — go read it, iykyk 👑

and that's the whole page, bestie 🎀 huge shoutout to the ./drivers/gpio source and the October 2026 date — struct ws16c48_gpio(9) out 💖
