STRUCT PLATFORM_NAND_CHIP(9)

💅 struct platform_nand_chip(9) 💅

okay bestie, welcome to the Kernel API Manual — we're looking at struct platform_nand_chip, and it is literally the chip level device structure, no cap ✨

🎀 NAME 🎀

struct platform_nand_chip — chip level device structure 💖

✨ SYNOPSIS ✨

       struct platform_nand_chip {
           int nr_chips;
           int chip_offset;
           int nr_partitions;
           struct mtd_partition *partitions;
           int chip_delay;
           unsigned int options;
           unsigned int bbt_options;
           const char **part_probe_types;
        };

🌸 Members 🌸

• nr_chips — max. number of chips to scan for 🔥 literally the upper limit on how many chips you're scanning for, bestie.
• chip_offset — chip number offset ✨ it's the offset for the chip number, periodt.
• nr_partitions — number of partitions pointed to by partitions (or zero) 🎀 so how many partitions partitions points at, or 0 if there are none.
• partitions — mtd partition list 🦋 the actual list of mtd partitions.
• chip_delay — R/B delay value in us ⏳ yes, R/B delay value, measured in us.
• options — Option flags, e.g. 16bit buswidth 👑 option flags go here, like 16bit buswidth.
• bbt_options — BBT option flags, e.g. NAND_BBT_USE_FLASH 💅 BBT option flags live here too, like NAND_BBT_USE_FLASH.
• part_probe_types — NULL-terminated array of probe types 🧚 a NULL-terminated array of probe types, iykyk.
