okay so bestie, this is the Kernel API Manual entry for hw_read(9), and it's literally a tiny little register-reading icon. No cap, it's giving “one job and it ate.” ✨

🌸 NAME 🌸

hw_read — reads from a hw register

🦋 SYNOPSIS 🦋

Here's the exact summoning line, character for character, no edits:

u32 hw_read (struct ci_hdrc *ci , enum ci_hw_regs reg , u32 mask );

🎀 ARGUMENTS 🎀

• ci — the controller. Main character energy, obvi.
• reg — register index. Which register slot we're peeking at.
• mask — bitfield mask. The little bit-filter for the bits.

💅 DESCRIPTION 💅

This function returns register contents. That's it, that's the whole meal. It hands you back the register contents, and honestly? Iconic. 🫶
