RK3399 firefly Android system is in early suspend state, how could it wake up by HID over I2C device?
adb command to enter early suspend: input keyevent 26
Android version: 8.1.0
Kernel : 4.4.126
Model: Firefly-RK3399
Note:
It can wake up by mouse input device from early suspend state, but can’t wake up by HID over I2C device. As I know, there is no CONFIG_HAS_EARLYSUSPEND menuconfig option in kernel 4.4. How should I modify kernel source to let system be waked up from early suspend state?
Any suggestion is highly appreciated.
Thanks! Author: gordontcp Time: 3/11/2022 10:56
