ENUM I3C_CCC_SETXTIME_SUBCMD(9)

💅 enum i3c_ccc_setxtime_subcmd(9) — Kernel API Manual, bestie edition

okay so real talk, this page is one of those tiny kernel API pages under the manual name Kernel API Manual, and honestly it's giving "I exist, I'm iconic, I'm just not gonna explain myself." ✨

🌸 NAME 🌸

enum i3c_ccc_setxtime_subcmd — the SETXTIME sub-commands, periodt.

🦋 SYNOPSIS 🦋

    I3C_CCC_SETXTIME_DT ,
    I3C_CCC_SETXTIME_ENTER_ASYNC_MODE0 ,
    I3C_CCC_SETXTIME_ENTER_ASYNC_MODE1 ,
    I3C_CCC_SETXTIME_ENTER_ASYNC_MODE2 ,
    I3C_CCC_SETXTIME_ENTER_ASYNC_MODE3 ,
    I3C_CCC_SETXTIME_ASYNC_TRIGGER ,
    I3C_CCC_SETXTIME_TPH ,

};

ngl bestie, that trailing blank line before the closing brace? that's canon. leave it alone. 💀

💖 Constants 💖

so here's the thing — the source doc literally has nothing written for any of these, and I'm not gonna make stuff up because that's not the vibe (that's lying, actually 🙈). Every single one is marked -- undescribed -- in the original, and here they all are, in order, with full name integrity:

• I3C_CCC_SETXTIME_ST — -- undescribed --
• I3C_CCC_SETXTIME_DT — -- undescribed --
• I3C_CCC_SETXTIME_ENTER_ASYNC_MODE0 — -- undescribed --
• I3C_CCC_SETXTIME_ENTER_ASYNC_MODE1 — -- undescribed --
• I3C_CCC_SETXTIME_ENTER_ASYNC_MODE2 — -- undescribed --
• I3C_CCC_SETXTIME_ENTER_ASYNC_MODE3 — -- undescribed --
• I3C_CCC_SETXTIME_ASYNC_TRIGGER — -- undescribed --
• I3C_CCC_SETXTIME_TPH — -- undescribed --
• I3C_CCC_SETXTIME_TU — -- undescribed --
• I3C_CCC_SETXTIME_ODR — -- undescribed --

lowkey ten constants, highkey zero descriptions. the audacity 😭 ten out of ten, no notes, we love a mystery.
