STRUCT TI_SCI_MSG_REQ_SET_CLOCK_PARENT(9)

💖 struct ti_sci_msg_req_set_clock_parent(9) 💖

okay bestie, welcome to the Kernel API Manual — this page is all about struct ti_sci_msg_req_set_clock_parent(9), and we're gonna set a clock parent without losing the plot. 💅

---

🌸 NAME 🌸

struct ti_sci_msg_req_set_clock_parent — Set the clock parent, periodt. 🎀

---

✨ SYNOPSIS ✨

struct ti_sci_msg_req_set_clock_parent {
    struct ti_sci_msg_hdr hdr;
    u32 dev_id;
    u8 clk_id;
    u8 parent_id;
    u32 clk_id_32;
    u32 parent_id_32;
};

---

🎀 Members 🎀

• hdr — Generic Header. That's the generic header, iconic and to the point. ✨
• dev_id — Device identifier this request is for. Like, which device are we even talking to, bestie? 🫶
• 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. Set to 255 if clock ID is greater than or equal to 255. 🕰️
• parent_id — The new clock parent is selectable by an index via this parameter. Set to 255 if clock ID is greater than or equal to 255. Yes, that's what the page says — keep it. 💅
• clk_id_32 — Clock identifier if clk_id field is 255. Big-ID energy. 🔥
• parent_id_32 — Parent identifier if parent_id is 255. Matching energy. 🌈

---

🌟 Description 🌟

Request type is TI_SCI_MSG_SET_CLOCK_PARENT, response is generic ACK / NACK message. That's the whole vibe: send the request, get a yes or a no. 🎀
