STRUCT MARVELL_NFC_TIMINGS(9)

💖 struct marvell_nfc_timings(9) 💖

✨ NAME ✨

okay so struct marvell_nfc_timings — straight out of the Kernel API Manual — is giving NAND controller timings expressed in NAND Controller clock cycles. that’s the whole vibe: timing values, clock cycles, NAND controller. no cap. 💅

🦋 SYNOPSIS 🦋

       struct marvell_nfc_timings {
           unsigned int tRP;
           unsigned int tRH;
           unsigned int tWP;
           unsigned int tWH;
           unsigned int tCS;
           unsigned int tCH;
           unsigned int tADL;
           unsigned int tAR;
           unsigned int tWHR;
           unsigned int tRHW;
           unsigned int tR;
        };

look at her. iconic struct energy, all unsigned int fields, absolutely serving kernel API realness. 👑

🎀 Members 🎀

• tRP — ND_nRE pulse width. literally the pulse width, bestie. ✨
• tRH — ND_nRE high duration. how long it stays high, periodt.
• tWP — ND_nWE pulse time. yes, pulse time. 🩷
• tWH — ND_nWE high duration. high-key just the high duration.
• tCS — enable signal setup time. setup era. 🎀
• tCH — enable signal hold time. hold it, hold it. 💅
• tADL — address to write data delay. the delay from address to write data.
• tAR — ND_ALE low to ND_nRE low delay. low-to-low delay, iykyk.
• tWHR — ND_nWE high to ND_nRE low for status read. status-read specific, no cap. 🌸
• tRHW — ND_nRE high duration, read to write delay. two things at once, main character energy. 🌟
• tR — ND_nWE high to ND_nRE low for read. read-specific, slay.

bestie, if you’re going deeper, the kernel file is ./drivers/mtd/nand/raw/marvell_nand.c, and these are the linked faves:

• struct marvell_nand_chip(9)
• struct marvell_nfc_caps(9)
• struct marvell_nfc(9)
• TO_CYCLES(9)

and that’s the cute little sign-off: this page is from the Kernel API Manual, source path ./drivers/mtd/nand/raw, dated October 2026, and it’s the page for struct marvell_nfc_timings(9). go off, bestie 🫶✨
