sdhci_zynqmp...lk_set_phase(9)

💅 sdhci_zynqmp_sdcardclk_set_phase — a Kernel API Manual moment 🎀

okay so bestie, we're in the Kernel API Manual today and this page is literally about sdhci_zynqmp...lk_set_phase(9) — yes the title's got that truncated group-chat nickname energy, iykyk. let's get into it 🦋

✨ NAME ✨

sdhci_zynqmp_sdcardclk_set_phase — Set the SD Output Clock Tap Delays 🌸

✨ SYNOPSIS ✨

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

✨ ARGUMENTS ✨

• hw — a pointer to the hardware clock structure, bestie. that's your entry ticket 🎟️
• degrees — the clock phase shift, and it lives between 0 - 359. not 360, not negative, we stay in our lane 💅

✨ DESCRIPTION ✨

Set the SD Output Clock Tap Delays for the Output path. that's the whole vibe. it's giving precise timing, it's giving clock-tap-delay realness ⏰✨

✨ RETURN ✨

0 on success, and an error value on error 😭 (yes that's it, that's the return section, we keep it iconic and brief 🫶)
