STRUCT ROCKCHIP_USB2PHY_CFG(9)

🌸 NAME 🌸

struct rockchip_usb2phy_cfg(9) — straight outta the Kernel API Manual — is literally the usb-phy configuration struct, and she’s serving main-character energy. 💅✨

🎀 SYNOPSIS 🎀

okay so here’s the exact struct, bestie, no edits, no cap:

struct rockchip_usb2phy_cfg {
    unsigned int    reg;
    unsigned int    num_ports;
    int (*phy_tuning)(struct rockchip_usb2phy *rphy);
    struct usb2phy_reg      clkout_ctl;
    struct usb2phy_reg      clkout_ctl_phy;
    const struct rockchip_usb2phy_port_cfg
port_cfgs[USB2PHY_NUM_PORTS];
    const struct rockchip_chg_det_reg       chg_det;
 };

💖 Members 💖

• reg — the address offset of grf for usb-phy config. yes, literally the little address coordinate for this config in GRF. 📍
• num_ports — specify how many ports that the phy has. count ’em, bestie. 🔢
• phy_tuning — phy default parameters tuning. her tuning hook, signature and all: int (*phy_tuning)(struct rockchip_usb2phy *rphy). 🛠️
• clkout_ctl — register to enable output clk of phy, when set in GRF. note the “when set in GRF” part, iykyk. ⏰
• clkout_ctl_phy — register to enable output clk of phy, when set inside phy. same clock-output goal, different setting spot. 🫶
• port_cfgs — usb-phy port configurations. it’s port_cfgs[USB2PHY_NUM_PORTS], a const struct rockchip_usb2phy_port_cfg situation. 🔌
• chg_det — charger detection registers. it’s const struct rockchip_chg_det_reg, and yes, charger detection said hi. 🔋

bestie, go peek at Kernel file ./drivers/phy/rockchip/phy-rockchip-inno-usb2.c, plus enum usb_chg_state(9), struct rockchip_chg_det_reg(9), struct rockchip_usb2phy_port_cfg(9), struct rockchip_usb2phy_port(9), and struct rockchip_usb2phy(9). that’s the whole squad. 💖
