STRUCT SUNXI_NAND_CHIP(9)

💖 NAME 💖

struct sunxi_nand_chip — literally the place where all your NAND chip device info lives, bestie ✨

okay so first things first, this whole page is from the Kernel API Manual, and the thing we're stanning today is struct sunxi_nand_chip — it's giving "one struct to hold all the deets about a NAND chip device" and honestly? iconic.

🦋 SYNOPSIS 🦋

struct sunxi_nand_chip {
    struct list_head node;
    struct nand_chip nand;
    struct sunxi_nand_hw_ecc ecc;
    unsigned long clk_rate;
    u32 timing_cfg;
    u32 timing_ctl;
    u8 *user_data_bytes;
    int nsels;
    struct sunxi_nand_chip_sel sels[];
};

like, that's the whole vibe right there 💅

🎀 Members 🎀

• node — this is the lil list glue, used to store NAND chips into a list 🔗
• nand — the base NAND chip structure, the main character energy of the whole thing 👑
• ecc — the ECC controller structure, keeping your data's skin clear ✨
• clk_rate — the clk_rate that this NAND chip needs, no cap ⏰
• timing_cfg — the TIMING_CFG register value for this NAND chip 🎚️
• timing_ctl — the TIMING_CTL register value for this NAND chip 🎛️
• user_data_bytes — an array of user data lengths for all the ECC steps, every single one, we don't skip 🍓
• nsels — how many CS lines this NAND chip requires, counted and everything 🔢
• sels — the array of CS lines descriptions, the whole squad 🌈
