STRUCT WCD934X_DDATA(9)

💖 struct wcd934x_ddata(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — and today's main character is struct wcd934x_ddata, aka the wcd934x driver data 🎀 like literally the lil' bundle of everything the wcd934x driver needs to keep track of. she's giving "backstage pass holder" energy, ngl. 🌸

✨ SYNOPSIS ✨

no cap, here's the whole struct in all her glory — copy it exactly, don't be weird about it:

struct wcd934x_ddata {
    struct regulator_bulk_data supplies[WCD934X_MAX_SUPPLY];
    struct regmap_irq_chip_data *irq_data;
    struct regmap *regmap;
    struct clk *extclk;
    struct device *dev;
    int irq;
 };

🦋 Members 🦋

• supplies — the wcd934x regulator supplies, bestie. yes, plural, she's an array of struct regulator_bulk_data, and there's WCD934X_MAX_SUPPLY of them because hydration is important 💅
• irq_data — the wcd934x irq_chip data, pointer to struct regmap_irq_chip_data. she's the interrupt lore keeper ✨
• regmap — the wcd934x regmap pointer, a struct regmap *. the register map bestie herself 🫶
• extclk — the External clock, struct clk *. she ticks, she tocks, she keeps everything on beat ⏰🎀
• dev — the device instance of the wcd934x slim device, a struct device *. this is the "who am i, really" field 😭
• irq — the irq for wcd934x, a plain old int. one number, endless interruptions 💀

real talk: this struct is just a cozy lil' container, but every pointer in here is load-bearing, so don't go yeeting fields out unless you actually know what you're doing 🙈
