mhi_power_down(9)

💖 NAME 💖

okay bestie, welcome to the mhi_power_down(9) page in the Kernel API Manual — and it's giving “clean shutdown with consequences” ✨. mhi_power_down powers down the MHI device and also destroys the 'struct device' for the channels associated with it. no cap.

also peep mhi_power_down_keep_dev(): it's a variant of this API that keeps the 'struct device' for channels (useful during suspend/hibernation) 🫶.

✨ SYNOPSIS ✨

void mhi_power_down (struct mhi_controller *mhi_cntrl , bool graceful );

🎀 ARGUMENTS 🎀

• mhi_cntrl — MHI controller. the main-character pointer, literally 💅
• graceful — Link is still accessible, so do a graceful shutdown process. yes bestie, be polite about it ✨
