💅 usb_ss_write_phycreg(9) — Kernel API Manual, bestie edition

okay so listen, this is a page from the Kernel API Manual and it's about one tiny little function that writes to a SSPHY register. It's giving "small but crucial", it's giving "don't touch unless you know what you're doing" 💖

✨ NAME ✨

usb_ss_write_phycreg — Write SSPHY register 🎀

🦋 SYNOPSIS 🦋

int usb_ss_write_phycreg (struct usb_phy *phy_dwc3 , u32 addr , u32 val );

so it takes three things and hands you back an int, no cap ✨

🌸 ARGUMENTS 🌸

• phy_dwc3 — the QCOM DWC3 phy context, aka the whole vibe of the phy you're working with 🫶
• addr — the SSPHY address you wanna write to. like, the destination, the target, the place 💅
• val — the value you're actually writing there. the payload. the main character 🔥

ngl there's no return value documented on this page, so just take your int and go, bestie 😭

💜 SEE ALSO 💜

• Kernel file ./drivers/phy/qualcomm/phy-qcom-ipq806x-usb.c — go read the source, it's literally right there 🧚
• usb_phy_write_readback(9)
• usb_ss_read_phycreg(9) — the read counterpart, because reading and writing are a package deal 💫

and that's the whole page, periodt 💀 mwah, go write some registers responsibly. this lil gem lives under ./drivers/phy/qualcomm and the manual clocked in at October 2026 🌈⭐🍓

slay, you're done here 💖
