sdhci_arasan..._recalc_rate(9)

💖 NAME 💖

sdhci_arasan_sampleclk_recalc_rate — bestie, this one just returns the sampling clock rate ✨

okay so real talk, we're in the Kernel API Manual rn and this function is literally the vibe check for your sampling clock 💅

---

🎀 SYNOPSIS 🎀

unsigned long sdhci_arasan_sampleclk_recalc_rate (struct clk_hw *hw ,
unsigned long parent_rate );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the hardware clock structure 🫶 like, the whole clock's main character energy lives here
• parent_rate — the parent rate, and no cap it should be the rate of clk_xin 💫

---

🌸 DESCRIPTION 🌸

So it returns the current actual rate of the sampling clock 👑 not the theoretical one, not the one you wished for, the actual one, periodt.

And like, why do we care? Because this is what you use to communicate with our PHY 🔥 that's the whole point, iykyk.

---

✨ RETURN ✨

The sample clock rate 💖 that's it, that's the return value, she's simple and she ate 🌈
