在進入 suspend 模式時, (echo mem > /sys/power/state) ,

為了減少 suspend 的電流,需要對 imx51 的 gpio 作重新設置嗎?

例如:設置為 High-Z (input) mode,以減少電流消耗。

在其他的 application processor 都有類似的動作,但是在 imx51 android bsp 中沒有看到。

請問 imx51 不需要這樣作嗎?


Translation: Subject---is it necessary to set GPIO pin to high-Z when entering Suspend mode in i.MX51 Androd 10.4?

When entering suspend mode, in order to reduce current, is it necessary to set GPIO pins? For example, set pin to High-Z (input) mode to reduce power consumption. In other application platform, it is required to do it. However, in i.MX51 bsp, it is not seen.

Does i.MX51 not need the action?
