🦋 qcom_ramp_controller_start 🦋

okay bestie, welcome to the Kernel API Manual, section 9 — today’s main character is qcom_ramp_controller_start, and it’s literally here to get a ramp controller initialized and started. no cap. 💅

int qcom_ramp_controller_start (struct qcom_ramp_controller *qrc );

🎀 ARGUMENTS 🎀

💅 DESCRIPTION 💅

okay so here’s the tea: the Ramp Controller needs to be initialized by programming the relevant registers with SoC-specific configuration. once that programming is done, the hardware will take care of the rest — and there is no further handling required. periodt. 💖

• 0 (zero) for success 🎉
• a negative number for error 😭
