clk_has_parent(9) 💅✨

okay so this is the clk_has_parent(9) page, straight outta the Kernel API Manual, and bestie we are gonna get you comfy with it 🫶

🌸 NAME 🌸

clk_has_parent — check if a clock is a possible parent for another ✨

🎀 SYNOPSIS 🎀

bool clk_has_parent (const struct clk *clk , const struct clk *parent );

🦋 ARGUMENTS 🦋

• clk — clock source
• parent — parent clock source

💖 DESCRIPTION 💖

so this function is for drivers that need to check that a clock can be the parent of another without actually changing the parent. literally just a vibe check, no parent-swapping happening here 💅

it returns true if parent is a possible parent for clk, and false otherwise. periodt ✨
