<p style="background:white"><span style="font-family:"Calibri","sans-serif";color:black">I am working with the linux hibernation code( swsusp hibernation framework) on an ARM based custom SOC. I am using some drivers like Nand Flash Controller driver as loadable modules.
<o:p></o:p></span></p>
<p style="background:white"><span style="font-family:"Calibri","sans-serif";color:black">As per my understanding , during hibernation kernel calls suspend for all the drivers while creating a snapshot. During resume, after the kernel resumes the snapshot (from
late_initcall – software_resme) , the kernel calls resume for all the drivers. <o:p>
</o:p></span></p>
<p style="background:white"><span style="font-family:"Calibri","sans-serif";color:black">As nand and some other drivers do not support suspend/resume, thus they fail to work on system resume. So is it fine to call driver_unregister/driver_register during hibernation/resume
for the drivers which do not support suspend/resume. I do not want the user to manually remove/insert the drivers on suspend/resume.<o:p></o:p></span></p>
