STRUCT EEPROM_93CX6(9)

🦋 struct eeprom_93cx6(9) — like, the control struct era 💅

okay so bestie, welcome to the Kernel API Manual page for struct eeprom_93cx6 — literally the control structure you use for setting the commands when you're reading eeprom data. yes, that's the whole vibe. let's get into it ✨

---

✨ NAME ✨

struct eeprom_93cx6 — the control structure for setting the commands for reading the eeprom data. that's it, that's the gig 🎀

---

🌸 SYNOPSIS 🌸

lowkey just look at it. it's giving gorgeous little struct:

struct eeprom_93cx6 {
    void *data;
    void (*register_read)(struct eeprom_93cx6 *eeprom);
    void (*register_write)(struct eeprom_93cx6 *eeprom);
    int width;
    unsigned int quirks;
  #define PCI_EEPROM_QUIRK_EXTRA_READ_CYCLE       BIT(0);
    char drive_data;
    char reg_data_in;
    char reg_data_out;
    char reg_data_clock;
    char reg_chip_select;
 };

not the #define just vibing in the middle of the struct 😭 iconic honestly. copy it exactly, no cap.

• data — your private pointer for the driver. she's yours, nobody else touches her 💖
• register_read — the handler that reads the eeprom register. important: this function should set all the reg_* fields. all of them. every single one. don't leave a girl hanging 💅
• register_write — the handler that writes to the eeprom register, using all the reg_* fields. yeah, the same crew. she uses all of them 🌈
• width — the eeprom width. should be one of the PCI_EEPROM_WIDTH_* defines. should being the operative word here 👀
• quirks — eeprom or controller quirks. everybody's got their little quirks, right? 🦋
• drive_data — set if we're driving the data line. main character energy for the data line ⭐
• reg_data_in — register field to indicate data input 🍓
• reg_data_out — register field to indicate data output 🧚
• reg_data_clock — register field to set the data clock. tick tock ⭐
• reg_chip_select — register field to set the chip select 👑

💜 Description 💜

so the way that this works: this structure is used for the communication between the driver and the eeprom_93cx6 handlers for reading the eeprom. like, it's the group chat between your driver and the handler, and everybody knows their role. no chaos, just vibes 🌸
