STRUCT AD2S1200_STATE(9)

💅 struct ad2s1200_state(9) 🎀

okay so this is from the Kernel API Manual bestie, and it's literally the whole tea on struct ad2s1200_state — the little struct that holds all the driver-instance-specific data. she's small, she's specific, she's giving main character energy for exactly one driver 🦋

✨ NAME ✨

struct ad2s1200_state — driver instance specific data. that's it, that's the vibe 💖

---

🌸 SYNOPSIS 🌸

struct ad2s1200_state {
    struct mutex lock;
    struct spi_device *sdev;
    struct gpio_desc *sample;
    struct gpio_desc *rdvel;
    __be16 rx;
 };

like look at her. five fields. immaculate. no cap 👑

---

💫 Members 💫

• lock — this one is the bodyguard 🫶 it protects both the GPIO pins and the rx buffer. everything guarded, nothing out here unguarded, periodt.
• sdev — the spi device. literally the device. iconic.
• sample — GPIO pin SAMPLE.
• rdvel — GPIO pin RDVEL.
• rx — buffer for spi transfers. that's where the bytes land 💅

lowkey reminder bestie: if you touch the GPIO pins or the rx buffer without holding lock, that's not slay, that's a bug 🙈
