STRUCT SDHCI_ARASAN_CLK_OPS(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME

struct sdhci_arasan_clk_ops — the Clock Operations for the Arasan SD controller, bestie 💖

okay so real talk, this is one of those little structs living inside the Kernel API Manual (yes, the actual Linux kernel docs, we're fancy now 👑), and it's basically the plug-in panel for all the clock stuff the Arasan SD host controller needs to do its job ✨

✨ SYNOPSIS

struct sdhci_arasan_clk_ops {
    const struct clk_ops *sdcardclk_ops;
    const struct clk_ops *sampleclk_ops;
 };

like, that's it. two pointers. two. that's the whole struct 💅 but the way that those two pointers carry so much responsibility? it's giving main character energy fr fr.

💅 Members

  • sdcardclk_ops — the operations for the output clock 🕐✨ literally the ones that handle the clock going out, the whole reason your card gets a signal at all, no cap.
  • sampleclk_ops — the operations for the sample clock 🎀 the one that does the sampling side of things, its own whole vibe, its own whole set of ops.
both are const struct clk_ops * btw — pointers to const, so nobody's out here rewriting the clk_ops tables at 3am. we love a read-only situation 🫶

🦋 SEE ALSO

okay bestie, buckle in, because this list is long and every single one of these is real and you're gonna need them 😭 all of them live in the kernel file ./drivers/mmc/host/sdhci-of-arasan.c — that's the whole neighbourhood 🏡

like, that's twenty-one entries. twenty-one!! not me counting them. okay I counted them. and you should read all of them, iykyk 🔥

so yeah, that's the whole page — short struct, iconic energy, zero filler 💜

this lil' beauty ships under ./drivers/mmc/host and the docs are dated October 2026 — go read it again sometime, mwah 😘🎀
