ti_sci_cmd_clk_get_parent(9)

okay bestie, this is ti_sci_cmd_clk_get_parent(9) from the Kernel API Manual — and she’s here to spill the tea on the current parent clock source 💖✨

🎀 NAME 🎀

ti_sci_cmd_clk_get_parent — get the current parent clock source, no cap 💅

✨ SYNOPSIS ✨

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

🌸 ARGUMENTS 🌸

• handle — pointer to TI SCI handle 🫶
• dev_id — device identifier that this request is for
• clk_id — clock identifier for the device on this request. Each device has it’s own set of clock inputs, and this indexes which clock input to modify 👑
• parent_id — current clock parent

💖 RETURN 💖

0 if all went well, else returns appropriate error value. literally the vibe check: zero means slay, anything else is the error bestie 💀
