exynos5_dmc_probe(9)

okay so bestie, this is the tea on exynos5_dmc_probe(9) from the Kernel API Manual 💅✨

🎀 NAME 🎀

exynos5_dmc_probe — probe function for the DMC driver. That's the whole name vibe, periodt.

🌸 SYNOPSIS 🌸

The signature is literally:

int exynos5_dmc_probe (struct platform_device *pdev );

🦋 ARGUMENTS 🦋

• pdev — the platform device for which the driver is going to be initialized. It's the main-character device getting set up, iykyk.

✨ DESCRIPTION ✨

So this function initializes the basic components: clocks, regulators, performance counters, etc. Then it reads out the product version and, based on that information, sets up internal structures for the controller (frequency and voltage) and for DRAM memory parameters: timings for each operating frequency. Finally it registers a new devfreq device for controlling DVFS of the DMC. Slay.
