STRUCT ROCKCHIP_CPUCLK(9)

💖 NAME 💖

okay bestie, welcome to the struct rockchip_cpuclk(9) page from the Kernel API Manual — this is literally about struct rockchip_cpuclk: information about clock supplied to a CPU core. yep, that's the whole vibe. 🎀

✨ SYNOPSIS ✨

here's the struct in all its glory, copied exactly so u can trust it, no cap:

       struct rockchip_cpuclk {
           struct clk_hw                           hw;
           struct clk                              *alt_parent;
           void __iomem                            *reg_base;
           struct notifier_block                   clk_nb;
           unsigned int                            rate_count;
           struct rockchip_cpuclk_rate_table       *rate_table;
           const struct rockchip_cpuclk_reg_data   *reg_data;
           spinlock_t *lock;
        };

okay so every field is doing main character work here:

• hw — handle between ccf and cpu clock. iykyk. 💅
• alt_parent — alternate parent clock to use when switching the speed of the primary parent clock. it's giving backup-parent energy. 🦋
• reg_base — base register for cpu-clock values. 📌
• clk_nb — clock notifier registered for changes in clock speed of the primary parent clock. bestie is on speed-watch. 👀
• rate_count — number of rates in the rate_table. counting the rates, periodt. 🔢
• rate_table — pll-rates and their associated dividers. iconic little table fr fr. 🌸
• reg_data — cpu-specific register settings. cpu-specific, exactly as it says. ✨
• lock — clock lock. protecting the vibe, lowkey essential. 🔒
