ti_sci_get_by_phandle(9)

💖 ti_sci_get_by_phandle(9) 💖

okay bestie, welcome to the Kernel API Manual page for ti_sci_get_by_phandle(9). We’re grabbing the TI SCI handle using a DT phandle, and it’s giving firmware main character energy 🧚✨

🌸 NAME 🌸

ti_sci_get_by_phandle — Get the TI SCI handle using DT phandle. that’s the whole name, no cap 💅

✨ SYNOPSIS ✨

const struct ti_sci_handle * ti_sci_get_by_phandle (struct device_node
       *np , const char *property );

🎀 ARGUMENTS 🎀

• np — device node. this is the node you’re passing in, bestie.
• property — property name containing phandle on TISCI node. yes, on the TISCI node, iykyk.

🦋 NOTE 🦋

🫶 important note, fr fr: The function does not track individual clients of the framework and is expected to be maintained by caller of TI SCI protocol library. ti_sci_put_handle must be balanced with successful ti_sci_get_by_phandle.

🔥 RETURN 🔥

• pointer to handle if successful
• else -EPROBE_DEFER if the instance is not ready
• -ENODEV if the required node handler is missing
• -EINVAL if invalid conditions are encountered
