dwc3_ref_clk_period(9)

💅 dwc3_ref_clk_period 💅

okay so bestie, this page is literally about dwc3_ref_clk_period — the reference clock period configuration 🕰️✨ and yes, it's a kernel function, we're doing big brain stuff today.

so the tea is: the default reference clock period depends on your hardware configuration. periodt. but for systems whose reference clock differs from that default, this function will set the clock period in the DWC3_GUCTL register. slay 💅🔥

✨ SYNOPSIS ✨

void dwc3_ref_clk_period (struct dwc3 *dwc );

like, it returns nothing (void) and takes exactly one arg. no cap. 🫶

🎀 ARGUMENTS 🎀

• dwc — pointer to our controller context structure 💖 that's the whole vibe, she just needs the context struct and she's good to go.

ngl this one is short and sweet — no giant option list, no scary errors, just clock period business. a little main character moment in core.c 🌸
