STRUCT RZV2H_CPG_PRIV(9)

✨ NAME ✨

okay so welcome to the Kernel API Manual entry for struct rzv2h_cpg_priv(9), bestie! The name is struct rzv2h_cpg_priv — Clock Pulse Generator Private Data. It's giving "the CPG's own private little data bundle," and honestly? iconic. 💅

🦋 SYNOPSIS 🦋

struct rzv2h_cpg_priv {
    struct device *dev;
    void __iomem *base;
    spinlock_t rmw_lock;
    struct clk **clks;
    unsigned int num_core_clks;
    unsigned int num_mod_clks;
    struct rzv2h_reset *resets;
    unsigned int num_resets;
    unsigned int last_dt_core_clk;
    struct clk_ops *ff_mod_status_ops;
    atomic_t *mstop_count;
    struct reset_controller_dev rcdev;
    struct rzv2h_pll_dsi_info pll_dsi_info[MAX_CPG_DSI_PLL];
};

🌸 Members 🌸

• dev — the CPG device. the main-character device reference, periodt.
• base — the CPG register block base address. that's where the registers live, no cap.
• rmw_lock — protects register accesses. it's the read-modify-write bodyguard keeping accesses from stepping on each other.
• clks — Array containing all Core and Module Clocks. literally the whole clock lineup.
• num_core_clks — Number of Core Clocks in clks[]. the headcount for the core-clock section.
• num_mod_clks — Number of Module Clocks in clks[]. the headcount for the module-clock section.
• resets — Array of resets. yep, the reset squad.
• num_resets — Number of Module Resets in info->resets[]. the reset tally.
• last_dt_core_clk — ID of the last Core Clock exported to DT. that's the DT export boundary, bestie.
• ff_mod_status_ops — Fixed Factor Module Status Clock operations. the ops for that clock flavor.
• mstop_count — Array of mstop values. a whole array of mstop counts, slay.
• rcdev — Reset controller entity. the reset-controller representation.
• pll_dsi_info — Array of PLL DSI information, holds the limits and parameters. it's giving PLL DSI details with limits and parameters included. 🫶
