Please let me know How can I use GPIO key button to wake up from sleep mode in I.Mx233.
Please help if example code is available.
If you use a device tree kernel, all you have to do is to pass 'gpio-key,wakeup;'. You can reference this commit:
Actually my customer is doing a smart watch on I.MX233, now every smartphone comes with power button which can be used to put phone active/sleep mode. We want to implement the same with I.MX233 how this can be achived.
Thanks in advance.
