STRUCT CPG_MSSR_PRIV(9)

💖 NAME 💖

okay bestie, welcome to the manual page for struct cpg_mssr_priv(9) from the Kernel API Manual — it’s literally the Clock Pulse Generator / Module Standby and Software Reset Private Data struct, and it’s giving main-character private-data energy ✨

🌸 SYNOPSIS 🌸

struct cpg_mssr_priv {
    struct cpg_mssr_pub pub;
  #ifdef CONFIG_RESET_CONTROLLER;
    struct reset_controller_dev rcdev;
  #endif;
    struct device *dev;
    enum clk_reg_layout reg_layout;
    struct device_node *np;
    unsigned int num_core_clks;
    unsigned int num_mod_clks;
    unsigned int last_dt_core_clk;
    const u16 *status_regs;
    const u16 *control_regs;
    const u16 *reset_regs;
    const u16 *reset_clear_regs;
    struct {
      u32 mask;
      u32 val;
    } smstpcr_saved[ARRAY_SIZE(mstpsr_for_gen4)];
    unsigned int *reserved_ids;
    unsigned int num_reserved_ids;
    struct clk *clks[];
};

🫶 Members 🫶

• pub — data passed to the clock registration callback 💌
• rcdev — optional reset controller entity, sitting pretty behind the CONFIG_RESET_CONTROLLER guard 🎀
• dev — the CPG/MSSR device 🧚
• reg_layout — CPG/MSSR register layout 🗂️
• np — device node in DT for this CPG/MSSR module 🌳
• num_core_clks — number of Core Clocks in clks[] 👑
• num_mod_clks — number of Module Clocks in clks[] 🧩
• last_dt_core_clk — ID of the last Core Clock exported to DT 🆔
• status_regs — pointer to status registers array 📌
• control_regs — pointer to control registers array 🎛️
• reset_regs — pointer to reset registers array 🔁
• reset_clear_regs — pointer to reset clearing registers array 🧼
• smstpcr_saved — saved SMSTPCR[] state: [].mask: mask of SMSTPCR[] bits under our control; [].val: saved values of SMSTPCR[] 💾
• reserved_ids — temporary used, reserved id list 🙈
• num_reserved_ids — temporary used, number of reserved id list 🔢
• clks — array containing all Core and Module Clocks ⏰
