STRUCT TEGRA_CLK_PLL_OUT(9)

✨ struct tegra_clk_pll_out(9) ✨

okay so bestie, we're in the Kernel API Manual today and the vibe is very "hardware clock divider realness". this is the struct tegra_clk_pll_out page — it's giving PLL divider down clock energy, and honestly? she ate. let's get into it 💅

---

🌸 NAME 🌸

struct tegra_clk_pll_out — the PLL divider down clock. literally that's her whole job. no cap.

---

🎀 SYNOPSIS 🎀

bestie. here's the whole struct, untouched, exactly as the kernel gods wrote it, don't come for me:

struct tegra_clk_pll_out {
    struct clk_hw   hw;
    void __iomem    *reg;
    u8 enb_bit_idx;
    u8 rst_bit_idx;
    spinlock_t *lock;
    u8 flags;
 };

---

💖 Members 💖

so these are the little guys that live inside her. let's meet the cast:

• hw — the handle that vibes between the common clock interfaces and the hardware-specific ones. she's the bridge, she's the main character, she translates for both sides ✨
• reg — the register that's holding the PLL divider. that's where the divider actually lives, <italic>*reg</italic> is a void __iomem pointer btw so she's memory-mapped and mysterious 🦋
• enb_bit_idx — the bit index that enables/disables the PLL divider. flip her one way, divider's on; other way, she's off 😴
• rst_bit_idx — the bit index that resets the PLL divider. chaotic but necessary. push it and she starts over 🔥
• lock — the register lock, a spinlock_t * fr. keeps everyone from touching the registers at the same time, because sharing is caring but racing is not 🌸
• flags — hardware-specific flags. mysterious. iconic. hardware-dependent so nobody can tell you exactly what's in there 👑

also ngl, enb_bit_idx, rst_bit_idx and flags are all u8 — small but mighty, and don't you forget it 💜

and that's the page!! mwah 💋 this one shipped from ./drivers/clk/tegra and it's dated October 2026 — so yeah, she's from the future, she's ahead of her time, and she's still struct tegra_clk_pll_out(9). iykyk. go read your kernel source bestie 🌈⭐
