sdhci_versal...lk_set_phase(9)

✨ sdhci_versal_sampleclk_set_phase(9) ✨

okay bestie, so we're deep in the Kernel API Manual today — like, we left userspace entirely and we're hanging out in driver land, and honestly? it's giving main character energy 🎀 this one's all about the SD Input Clock Tap Delays, no cap.

---

🌸 NAME 🌸

sdhci_versal_sampleclk_set_phase — literally just sets the SD Input Clock Tap Delays 💅 that's it, that's the whole vibe.

---

🦋 SYNOPSIS 🦋

int sdhci_versal_sampleclk_set_phase (struct clk_hw *hw , int degrees );

---

💖 ARGUMENTS 💖

• hw — pointer to the hardware clock structure. like, the clock thing itself, the actual object, she's the main character here 🕰️
• degrees — the clock phase shift, and it lives in the range 0 - 359. yes, degrees, like a circle, because that's how phase shifts roll ✨

---

🔥 DESCRIPTION 🔥

so what does she actually do?? she sets the SD Input Clock Tap Delays — specifically for the Input path 💫 that's the entire description. short, sweet, iconic. no notes.

---

⭐ RETURN ⭐

0 on success, and an error value on error 😭 (iykyk — kernel functions are so real for this).

ngl bestie, always check the return value. 0 = slay, anything else = vibe check failed 💀

🫶 friendly reminder that sdhci_versal_sdcardclk_set_phase(9) is a different function — she's the output-path sister, don't get them twisted bestie 💅
