STRUCT CLK_GPIO(9)

🌸 struct clk_gpio(9) 🌸

okay bestie, welcome to the Kernel API Manual 💅 this one's all about struct clk_gpio — the gpio gated clock, and it's literally iconic for reasons we're about to get into 🎀

---

✨ NAME ✨

struct clk_gpio — gpio gated clock, no cap 🫶

---

🦋 SYNOPSIS 🦋

struct clk_gpio {
    struct clk_hw   hw;
    struct gpio_desc *gpiod;
 };

---

💖 Members 💖

• hw — the handle between common and hardware-specific interfaces, the little bridge energy we love to see 🌈
• gpiod — the gpio descriptor, aka the gpio's main character paperwork 👑

---

🌸 Description 🌸

so basically this is a clock with a gpio control, right? it uses that gpio to enable and disable the parent clock or to switch between two parents by asserting or deasserting the gpio 🔥 the way it just flips a pin and the whole clock situation changes? obsessed.

it implements .enable, .disable and .is_enabled or .get_parent, .set_parent and .determine_rate — and which set you get depends on which clk_ops is used, iykyk 💅

• basic clock multiplexer which can be controlled with a gpio output(9) ⭐
• gated fixed clock, controlled with a gpio output and a regulator(9) 💜
• struct clk_gated_fixed(9) 👑

and that's the whole vibe, bestie — go forth and gate those clocks 💖
