💅 sdhci_arasan_register_sdcardclk — the Kernel API Manual, bestie edition 🌸

okay so real talk, this is from the Kernel API Manual and it's the page for sdhci_arasan_register_sdcardclk, which lowkey has the longest name ever but we move 💖

✨ NAME ✨

sdhci_arasan_register_sdcardclk — literally just registers the sdcardclk so a PHY can use it. that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

int sdhci_arasan_register_sdcardclk (struct sdhci_arasan_data
*sdhci_arasan , struct clk *clk_xin , struct device *dev );

three args, one int coming back at you, no cap ✨

🌈 ARGUMENTS 🌈

  • sdhci_arasan — our very own private data structure 🫶 like, ours, our little guy.
  • clk_xin — pointer to the functional clock ⭐
  • dev — pointer to our struct device 👑

💜 DESCRIPTION 💜

so some PHY devices are nosy (affectionate) and genuinely need to know what the actual card clock is 🌸 and the way they find out? we hand them a clock through the common clock framework so they can go query it themselves. it's giving "here bestie, look it up" 😭✨

🔥 RETURN 🔥

0 on success 🎉 and an error value on error 😭💀 (yes that's the whole return section, it ate and left no crumbs)
