STRUCT DENALI_CHIP_SEL(9)

✨ NAME ✨

struct denali_chip_sel — per-CS data of Denali NAND

okay so real talk, this little struct is straight out of the Kernel API Manual (that's section 9 bestie, the kernel interfaces girlies) and it's literally the vibe-holder for one chip select on a Denali NAND controller. per-CS. periodt. 🦋

🌸 SYNOPSIS 🌸

struct denali_chip_sel {
    int bank;
    u32 hwhr2_and_we_2_re;
    u32 tcwaw_and_addr_2_data;
    u32 re_2_we;
    u32 acc_clks;
    u32 rdwr_en_lo_cnt;
    u32 rdwr_en_hi_cnt;
    u32 cs_setup_cnt;
    u32 re_2_re;
 };

no cap, that's the whole glow-up. nine fields, all doing their own little thing 💅

💜 Members 💜

• bank — the bank id of the controller that this CS is hooked up to 🫶
• hwhr2_and_we_2_re — the value of timing register HWHR2_AND_WE_2_RE ✨
• tcwaw_and_addr_2_data — the value of timing register TCWAW_AND_ADDR_2_DATA ✨
• re_2_we — the value of timing register RE_2_WE ✨
• acc_clks — the value of timing register ACC_CLKS ✨
• rdwr_en_lo_cnt — the value of timing register RDWR_EN_LO_CNT ✨
• rdwr_en_hi_cnt — the value of timing register RDWR_EN_HI_CNT ✨
• cs_setup_cnt — the value of timing register CS_SETUP_CNT ✨
• re_2_re — the value of timing register RE_2_RE ✨

like, yes, it's a lot of timing registers, but every single one is a real field and every single one mirrors a real register name, so don't come for me 😭 just copy them exactly, iykyk

that's the whole page bestie, sourced from ./drivers/mtd/nand/raw, dated October 2026, and yes it's struct denali_chip_sel(9) — mwah, bye 🧚💖
