STRUCT ROCKCHIP_USB2PHY_PORT_CFG(9)

💖 struct rockchip_usb2phy_port_cfg(9) 💖

okay so bestie, this is a page straight out of the Kernel API Manual — the manual name is literally struct rockc...phy_port_cfg(9) (yes, the header truncates it like that, it's giving "we ran out of room on the label"). It's the struct that holds all the usb-phy port configuration for Rockchip's USB2 PHY. Let's get into it 🎀

✨ NAME ✨

struct rockchip_usb2phy_port_cfg — usb-phy port configuration. that's it, that's the whole vibe. it's the config struct. it holds registers. it's iconic 💅

🌸 SYNOPSIS 🌸

struct rockchip_usb2phy_port_cfg {
    struct usb2phy_reg      phy_sus;
    struct usb2phy_reg      bvalid_det_en;
    struct usb2phy_reg      bvalid_det_st;
    struct usb2phy_reg      bvalid_det_clr;
    struct usb2phy_reg      disfall_en;
    struct usb2phy_reg      disfall_st;
    struct usb2phy_reg      disfall_clr;
    struct usb2phy_reg      disrise_en;
    struct usb2phy_reg      disrise_st;
    struct usb2phy_reg      disrise_clr;
    struct usb2phy_reg      idfall_det_en;
    struct usb2phy_reg      idfall_det_st;
    struct usb2phy_reg      idfall_det_clr;
    struct usb2phy_reg      idrise_det_en;
    struct usb2phy_reg      idrise_det_st;
    struct usb2phy_reg      idrise_det_clr;
    struct usb2phy_reg      ls_det_en;
    struct usb2phy_reg      ls_det_st;
    struct usb2phy_reg      ls_det_clr;
    struct usb2phy_reg      utmi_avalid;
    struct usb2phy_reg      utmi_bvalid;
    struct usb2phy_reg      utmi_id;
    struct usb2phy_reg      utmi_ls;
    struct usb2phy_reg      utmi_hstdet;
 };

no cap, every single member is a struct usb2phy_reg — consistent queen behavior 👑 twenty-four of them. we love a uniform cast.

🦋 Members 🦋

• phy_sus — phy suspend register. the "go to sleep" switch, lowkey 🦋
• bvalid_det_en — vbus valid rise detection enable register. turns the detector on 💖
• bvalid_det_st — vbus valid rise detection status register. tells you what the detector saw 👀
• bvalid_det_clr — vbus valid rise detection clear register. wipes the status clean, fresh start energy ✨
• disfall_en — host disconnect fall edge detection enable.
• disfall_st — host disconnect fall edge detection state.
• disfall_clr — host disconnect fall edge detection clear.
• disrise_en — host disconnect rise edge detection enable.
• disrise_st — host disconnect rise edge detection state.
• disrise_clr — host disconnect rise edge detection clear.
• idfall_det_en — id detection enable register, falling edge. (yes, falling edge, write that down 📝)
• idfall_det_st — id detection state register, falling edge.
• idfall_det_clr — id detection clear register, falling edge.
• idrise_det_en — id detection enable register, rising edge. (and this one's rising, don't mix them up bestie 😭)
• idrise_det_st — id detection state register, rising edge.
• idrise_det_clr — id detection clear register, rising edge.
• ls_det_en — linestate detection enable register.
• ls_det_st — linestate detection state register.
• ls_det_clr — linestate detection clear register.
• utmi_avalid — utmi vbus avalid status register. (that's "avalid" with two a's, keep it exactly like that 🙈)
• utmi_bvalid — utmi vbus bvalid status register.
• utmi_id — utmi id state register.
• utmi_ls — utmi linestate state register.
• utmi_hstdet — utmi host disconnect register. the disconnect gossip column fr fr 💀
