STRUCT ROCKCHIP_USB2PHY(9)

💖 NAME 💖

struct rockchip_usb2phy — the driver data for the usb2.0 phy, bestie. that's it, that's the whole vibe ✨

🌸 SYNOPSIS 🌸

okay so here's the whole struct, every single field, no cap:

struct rockchip_usb2phy {
    struct device   *dev;
    struct regmap   *grf;
    struct regmap   *phy_base;
    struct clk_bulk_data    *clks;
    struct clk      *clk480m;
    struct clk_hw   clk480m_hw;
    int num_clks;
    struct reset_control    *phy_reset;
    enum usb_chg_state      chg_state;
    enum power_supply_type  chg_type;
    u8 dcd_retries;
    struct extcon_dev       *edev;
    int irq;
    const struct rockchip_usb2phy_cfg       *phy_cfg;
    struct rockchip_usb2phy_port    ports[USB2PHY_NUM_PORTS];
 };

🧚 MEMBERS 🧚

the way each one of these has a whole personality, let's go 🫶

• dev — pointer to device. the main character, fr.
• grf — the General Register Files regmap.
• phy_base — the USB PHY regmap. yes bestie, a separate regmap, keep up 💅
• clks — array of phy input clocks. an array, so like, multiple.
• clk480m — clock struct of phy output clk.
• clk480m_hw — clock struct of phy output clk management.
• num_clks — number of phy input clocks. it counts them. iconic.
• phy_reset — phy reset control.
• chg_state — states involved in USB charger detection.
• chg_type — USB charger types.
• dcd_retries — the retry count used to track Data contact detection process. it's giving perseverance 💀
• edev — extcon device for notification registration
• irq — muxed interrupt for single irq configuration
• phy_cfg — phy register configuration, assigned by driver data.
• ports — phy port instance. hi little port 🎀

lowkey go read all of these too, iykyk:

okay that's the whole page, mwah 💋 this one lives at ./drivers/phy/rockchip and it's dated October 2026 — like, from the future?? anyway, it's part of the Kernel API Manual, and that's the tea 🍓✨ periodt.
