STRUCT STMPE(9)

🌸 NAME 🌸

okay so this is struct stmpe(9) — the STMPE MFD structure, and bestie it's giving kernel-internals main character energy. It's a struct page, not a command, so no cap: we're looking at fields, not flags. 💅

✨ SYNOPSIS ✨

here's the whole struct, verbatim, because we do not mess with code:

struct stmpe {
    struct regulator *vcc;
    struct regulator *vio;
    struct mutex lock;
    struct mutex irq_lock;
    struct device *dev;
    struct irq_domain *domain;
    void *client;
    struct stmpe_client_info *ci;
    enum stmpe_partnum partnum;
    struct stmpe_variant_info *variant;
    const u8 *regs;
    int irq;
    int num_gpios;
    u8 ier[2];
    u8 oldier[2];
    struct stmpe_platform_data *pdata;
    u8 sample_time;
    u8 mod_12b;
    u8 ref_sel;
    u8 adc_freq;
};

💅 Members 💅

time for the member-by-member vibe check, bestie:

• vcc — optional VCC regulator.
• vio — optional VIO regulator.
• lock — lock protecting I/O operations.
• irq_lock — IRQ bus lock.
• dev — device, mostly for dev_dbg.
• client — client - i2c or spi.
• ci — client specific information.
• partnum — part number.
• variant — the detected STMPE model number.
• regs — list of addresses of registers which are at different addresses on different variants. Indexed by one of STMPE_IDX_*.
• irq — irq number for stmpe.
• num_gpios — number of gpios, differs for variants.
• ier — cache of IER registers for bus_lock.
• oldier — cache of IER registers for bus_lock.
• pdata — platform data.

🫶 tiny note: the struct also has domain, sample_time, mod_12b, ref_sel, and adc_freq in the code block above, but this page doesn't give each one its own member blurb, so I'm not inventing lore. Periodt.

shoutout to the footer info: this page comes from ./include/linux/mfd, dated October 2026, and it's struct stmpe(9) — bye bestie, slay your kernel adventures 💖✨🎀
