STRUCT AD7303_STATE(9)

✨ NAME ✨

okay so bestie, this page is from the Kernel API Manual, and it’s all about struct ad7303_state — literally driver instance specific data. no cap, it’s giving “one struct to hold the per-instance state” energy. 🫶

🌸 SYNOPSIS 🌸

here’s the whole struct, copied exactly so you can vibe-check it:

       struct ad7303_state {
           struct spi_device *spi;
           uint16_t config;
           uint8_t dac_cache[2];
           struct regulator *vdd_reg;
           struct regulator *vref_reg;
           struct mutex lock;
           __be16 data;
        };

💅 Members 💅

• spi — the device for this driver instance. it’s literally the SPI device this driver instance is attached to 🫶
• config — cached config register value. keeping that register value cached, periodt ✨
• dac_cache — current DAC raw value (chip does not support readback). yes bestie, that parenthetical is real: the chip does not support readback 😭
• vdd_reg — reference to VDD regulator. highkey just a reference to the VDD regulator 🔥
• vref_reg — reference to VREF regulator. same vibe, but for VREF 💜
• lock — protect writes and cache updates. the lock is there to protect writes and cache updates, no cap 🔒
• data — spi transfer buffer. literally the SPI transfer buffer 🎀
