STRUCT MU3C_IPPC_REGS(9)

💅 struct mu3c_ippc_regs(9) 💅

okay bestie, welcome to the Kernel API Manual entry for this little kernel struct 💖. It's giving “MTK ssusb ip port control registers” realness, and we're gonna keep every field exactly where it belongs. No cap.

✨ NAME ✨

struct mu3c_ippc_regs — MTK ssusb ip port control registers

• @ip_pw_ctr0~3: ip power and clock control registers
• @ip_pw_sts1~2: ip power and clock status registers

🌸 SYNOPSIS 🌸

Here's the struct in all its little-endian glory — copy it exactly, bestie, every field and every reserved slot included:

struct mu3c_ippc_regs {
    __le32 ip_pw_ctr0;
    __le32 ip_pw_ctr1;
    __le32 ip_pw_ctr2;
    __le32 ip_pw_ctr3;
    __le32 ip_pw_sts1;
    __le32 ip_pw_sts2;
    __le32 reserved0[3];
    __le32 ip_xhci_cap;
    __le32 reserved1[2];
    __le64 u3_ctrl_p[MU3C_U3_PORT_MAX];
    __le64 u2_ctrl_p[MU3C_U2_PORT_MAX];
    __le32 reserved2;
    __le32 u2_phy_pll;
    __le32 reserved3[33];
};
