eqep in linux 4.4.38+ not working

[abhilash h]

Dear All,

I am using linux kernel 4.4.38+ with busybox as rfs.

I have loaded bone_eqep2b-00A0.dtbo  to slots.
 i.e
# echo bone_eqep2b > /sys/devices/platform/bone_capemgr/slots

Then it got loaded

[   35.295161] bone_capemgr bone_capemgr: part_number 'bone_eqep2b', version 'N/A'                              
[   35.302625] bone_capemgr bone_capemgr: slot #4: override                                                     
[   35.307977] bone_capemgr bone_capemgr: Using override eeprom data at slot 4                                  
[   35.314984] bone_capemgr bone_capemgr: slot #4: 'Override Board Name,00A0,Override Manuf,bone_eqep2b'        
[   35.332763] bone_capemgr bone_capemgr: slot #4: dtbo 'bone_eqep2b-00A0.dtbo' loaded; overlay id #0        

But in the /sys/devices/platform/ocp/48304000.epwmss/48304180.eqep  i can see only
# ls                                                                                                            
driver_override  of_node          subsystem                                                                     
modalias         power            uevent  

There are no period, or position files to read.
It would be great if someone could help me out.

Regards,
Abhilash
