STRUCT CLK_WZRD(9)

🎀 NAME 🎀

Hiii bestie 💖 welcome to the struct clk_wzrd(9) page from the Kernel API Manual. This one is all about struct clk_wzrd — the clock wizard private data structure — and it’s lowkey the struct’s whole little info stash ✨. It ate and left no crumbs, fr fr.

✨ SYNOPSIS ✨

Okay so here’s the struct, exactly as written — no edits, no cap 🫶:

       struct clk_wzrd {
           struct notifier_block nb;
           void __iomem *base;
           struct clk *clk_in1;
           struct clk *axi_clk;
           struct clk_hw *clks_internal[wzrd_clk_int_max];
           unsigned int speed_grade;
           bool suspended;
           struct clk_hw_onecell_data clk_data;
        };

💅 Members 💅

• nb — Notifier block. Yep, that’s the member, bestie 💜.
• base — Memory base. The memory-base member, periodt 🧚.
• clk_in1 — Handle to input clock 'clk_in1' 🎀.
• axi_clk — Handle to input clock 's_axi_aclk' 🌸.
• clks_internal — Internal clocks. The internal clocks crew, literally 💅.
• speed_grade — Speed grade of the device. It’s giving device speed-grade realness ✨.
• suspended — Flag indicating power state of the device. Power-state flag behavior, iykyk 😭.
• clk_data — Output clock data. The output clock data, slay 💖.

Go read those too, bestie — main character kernel-file energy fr fr 🔥.
