STRUCT STM32_ADC_COMMON(9)

💅 NAME

struct stm32_adc_common — the stm32 ADC driver's common data, like the shared group chat for all the instances bestie, not just one 💖

okay so this is from the Kernel API Manual and it's literally the struct that every single stm32 ADC instance shares, no cap 👑

✨ SYNOPSIS

struct stm32_adc_common {
    void __iomem                    *base;
    phys_addr_t phys_base;
    unsigned long                   rate;
    int vref_mv;
    spinlock_t lock;
 };

🫶 MEMBERS

• base — the base cpu addr for the control registers 🎀 that's where the registers live in cpu-address-land
• phys_base — the base physical addr for those same control registers, iykyk ✨
• rate — the clock rate used for the analog circuitry 🌸 so like, the speed the analog bits are running at
• vref_mv — the vref voltage, measured in mv 💜
• lock — a spinlock_t, the classic spinlock 🌀 keeping things from stepping on each other

• the kernel file ./drivers/iio/adc/stm32-adc-core.h — go read it, it's giving source of truth 📖

bestie reminder: every field above is exactly what the kernel says, so don't go renaming anything 💀

that's the whole page, mwah 💋 this iconic little entry lives in ./drivers/iio/adc and it's dated October 2026 — periodt, go forth and read your headers 🧚💖🌟
