STRUCT STM32_DFSDM(9)

🎀 struct stm32_dfsdm(9) 🎀

okay so bestie, welcome to the struct stm32_dfsdm(9) page from the Kernel API Manual — it’s giving major shared driver lore energy 💖. This is the common data for the stm32 FDSDM driver (for all instances), so every instance is literally sharing this whole vibe. No cap.

✨ NAME ✨

struct stm32_dfsdm — the stm32 FDSDM driver common data (for all instances) 🫶

🌟 SYNOPSIS 🌟

       struct stm32_dfsdm {
           void __iomem    *base;
           phys_addr_t phys_base;
           struct regmap *regmap;
           struct stm32_dfsdm_filter *fl_list;
           unsigned int num_fls;
           struct stm32_dfsdm_channel *ch_list;
           unsigned int num_chs;
           unsigned int spi_master_freq;
        };

💅 Members 💅

• base — the control registers base CPU addr, periodt 💅
• phys_base — the DFSDM IP register physical address, iconic.
• regmap — the regmap for register read/write, fr fr.
• fl_list — the filter resources list 🎀
• num_fls — how many filter resources are available, literally.
• ch_list — the channel resources list 🦋
• num_chs — how many channel resources are available, no cap.
• spi_master_freq — the SPI clock out frequency ⭐
