sdhci_s3c_get_min_clock(9)

🌸 NAME 🌸

okay so bestie, this is sdhci_s3c_get_min_clock(9) — yes, from the Kernel API Manual — and it’s literally the callback to get the minimal supported clock value. no cap, that’s the whole name vibe 💅

✨ SYNOPSIS ✨

the signature is giving:

unsigned int sdhci_s3c_get_min_clock (struct sdhci_host *host );

🎀 ARGUMENTS 🎀

• host — the SDHCI host being queried 🫶

💅 DESCRIPTION 💅

okay so here’s the tea: to init mmc host properly, a minimal clock value is needed. literally required for a clean setup ✨

for high system bus clock’s values, the standard formula gives values out of allowed range — not me, that’s just what happens 😭. the clock still can be set to lower values, though, if a clock source other than the system bus is selected. so yeah, the lower-value option is still there when that other clock source is picked 🦋
