STRUCT XGENE_GPIO_SB(9)

okay so bestie, you're in the Kernel API Manual, specifically struct xgene_gpio_sb(9), and it's literally the page for the GPIO-Standby private data structure 💅✨ Not me being obsessed with a private data struct, but here we are.

✨ NAME ✨

struct xgene_gpio_sb — GPIO-Standby private data structure. That's the whole name, periodt 🎀

🦋 SYNOPSIS 🦋

the exact shape of this struct, no cap:

       struct xgene_gpio_sb {
           struct gpio_generic_chip chip;
           void __iomem            *regs;
           struct irq_domain       *irq_domain;
           u16 irq_start;
           u16 nirq;
           u16 parent_irq_base;
        };

🌸 Members 🌸

• chip — Generic GPIO chip data. It's giving "generic chip but make it the main character" 💅
• regs — GPIO register base offset. The address math starts here, bestie ✨
• irq_domain — GPIO interrupt domain. Interrupt lore, no cap 🦋
• irq_start — GPIO pin that start support interrupt. So the interrupt-support era begins at this pin 🌸
• nirq — Number of GPIO pins that supports interrupt. Count 'em, bestie 🔥
• parent_irq_base — Start parent HWIRQ. Where the parent HWIRQ starts, periodt 👑
