STRUCT IOH_GPIO(9)

✨ NAME ✨

okay so bestie, this page is all about struct ioh_gpio — the GPIO private data structure — and we are absolutely in the Kernel API Manual, section 9. no cap, that's the whole name vibe. 💅

🎀 SYNOPSIS 🎀

here is the struct in all its exact glory, copied character for character so you can screenshot it for the group chat:

       struct ioh_gpio {
           void __iomem *base;
           struct ioh_regs __iomem *reg;
           struct device *dev;
           struct gpio_chip gpio;
           struct ioh_gpio_reg_data ioh_gpio_reg;
           u32 gpio_use_sel;
           int ch;
           int irq_base;
           raw_spinlock_t *spinlock;
        };

• base — the PCI base address of Memory mapped I/O register. literally the address energy. 🌈
• reg — the Memory mapped IOH GPIO register list. ✨
• dev — pointer to device structure. 🫶
• gpio — data for GPIO infrastructure. 👑
• ioh_gpio_reg — Memory mapped Register data is saved here when suspend 😴
• gpio_use_sel — save the GPIO_USE_SEL1~4 register for PM 💅
• ch — indicate GPIO channel 🎀
• irq_base — save base of IRQ number for interrupt 🔥
• spinlock — shared register access lock 🔒
