ti_sci_cmd_clk_set_parent(9)

💖 NAME 💖

Okay bestie, welcome to ti_sci_cmd_clk_set_parent from the Kernel API Manual — this is the page for setting the clock source of a specific device clock. No cap, that's the name vibe. 💅

✨ SYNOPSIS ✨

int ti_sci_cmd_clk_set_parent (const struct ti_sci_handle *handle , u32
       dev_id , u32 clk_id , u32 parent_id );

🌸 ARGUMENTS 🌸

• handle — pointer to TI SCI handle. Like, the main character pointer you pass in. 🫶
• dev_id — Device identifier this request is for.
• clk_id — Clock identifier for the device for this request. Each device has its own set of clock inputs. This indexes which clock input to modify.
• parent_id — Parent clock identifier to set.

💅 RETURN 💅

0 if all went well, else returns the appropriate error value. That's the vibe check: zero means slay, anything else is the error-value situation. 😭
