STRUCT STMPE_VARIANT_INFO(9)

🌸 NAME 🌸

struct stmpe_variant_info — variant-specific information. Okay bestie, this is the Kernel API Manual page for that exact struct, and it’s giving extremely niche kernel-struct main character energy. ✨

✨ SYNOPSIS ✨

struct stmpe_variant_info {
    const char *name;
    u16 id_val;
    u16 id_mask;
    int num_gpios;
    int af_bits;
    const u8 *regs;
    struct stmpe_variant_block *blocks;
    int num_blocks;
    int num_irqs;
    int (*enable)(struct stmpe *stmpe, unsigned int blocks, bool
enable);
    int (*get_altfunc)(struct stmpe *stmpe, enum stmpe_block block);
    int (*enable_autosleep)(struct stmpe *stmpe, int autosleep_timeout);
};

💅 Members 💅

Vibe check on every member, because they all matter — no skipping, fr fr. 💖

• name — part name 🎀
• id_val — content of CHIPID register ⭐
• id_mask — bits valid in CHIPID register for comparison with id_val 💅
• num_gpios — number of GPIOS 🌈
• af_bits — number of bits used to specify the alternate function 🦋
• regs — variant specific registers. 📁
• blocks — list of blocks present on this device 🧚
• num_blocks — number of blocks present on this device 🔥
• num_irqs — number of internal IRQs available on this device ⚡
• enable — callback to enable the specified blocks. Called with the I/O lock held. 👑
• get_altfunc — callback to get the alternate function number for the specific block 🎯
• enable_autosleep — callback to configure autosleep with specified timeout 🌙

bestie note: enable is literally called with the I/O lock held — that detail is iconic and important, so don’t lose it. 💅
