STRUCT EXYNOS_HSI2C_VARIANT(9)

💅 struct exynos_hsi2c_variant(9) — the kernel API manual, but make it cute

okay so bestie, welcome to the glow-up of struct exynos_hsi2c_variant, straight out of the kernel API manual. this is your main character struct, the one carrying the platform-specific HSI2C driver data. yes, that HSI2C. no cap, this one's a little baby struct but she's important 💖

---

✨ NAME ✨

struct exynos_hsi2c_variant — platform specific HSI2C driver data 🎀

like, literally what it says on the tin: it's the struct that holds the platform-specific config for the HSI2C module. iconic behavior.

---

🌸 SYNOPSIS 🌸

here's the whole vibe, verbatim, don't touch:

struct exynos_hsi2c_variant {
    unsigned int            fifo_depth;
    enum i2c_type_exynos    hw;
 };

two members. that's it. she's lowkey minimal and I respect it 🫶

---

🦋 Members 🦋

• fifo_depth — the fifo depth supported by the HSI2C module. yes bestie, the depth. of the fifo. that's the number, that's the whole job 💅
• hw — the hardware variant of Exynos I2C controller. type is enum i2c_type_exynos, so it's out here telling you which Exynos I2C controller you're dealing with 🧚

---

💜 Description 💜

so what does this struct actually do? it specifies the platform specific configuration of the HSI2C module. that's the assignment. that's the vibe check. she holds the per-platform deets and the driver reads them and everybody slays ✨

---

🔥 Note 🔥

ngl, this is the important footnote: a structure for driver specific platform data is used for future expansion of its usage. so like — it's built this way on purpose, so it can grow later. foresight! main character planning energy 👑

bestie pls don't go assuming anything beyond what's written here, the original said "future expansion" and that's the whole tea ☕
