STRUCT AD5770R_STATE(9)

✨ struct ad5770r_state(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 — this is the page for struct ad5770r_state, which is literally just the driver instance specific data for the AD5770R DAC driver. like, it's the lil bundle of state that keeps track of one driver instance. that's it, that's the vibe check. 🦋

🌸 SYNOPSIS 🌸

struct ad5770r_state {
    struct spi_device               *spi;
    struct regmap                   *regmap;
    struct gpio_desc                *gpio_reset;
    struct ad5770r_out_range        output_mode[AD5770R_MAX_CHANNELS];
    int vref;
    bool ch_pwr_down[AD5770R_MAX_CHANNELS];
    bool internal_ref;
    bool external_res;
    u8 transf_buf[2];
};

🎀 Members 🎀

• spi — an spi_device. that's the SPI device handle, bestie, iykyk 🫶
• regmap — a regmap, the register map handle the driver does its register poking through ✨
• gpio_reset — the gpio descriptor for the reset line 🔥
• output_mode — this array contains channels output ranges 💅 (one entry per channel, built on AD5770R_MAX_CHANNELS)
• vref — the reference value, an int, iconic 👑
• ch_pwr_down — the powerdown flags, a bool array indexed over AD5770R_MAX_CHANNELS 😴
• internal_ref — the internal reference flag 💫
• external_res — the external 2.5k resistor flag 🍓
• transf_buf — a cache aligned buffer for spi read/write, u8 transf_buf[2], no cap ⭐
