Thanks Richard for the information.

As per manual page,

boundary_clock_jbod
When running as a boundary clock (that is, when more than one network interface 
is configured), ptp4l performs a sanity check to make sure that all of the 
ports share the same hardware clock device. This option allows ptp4l to work as 
a boundary clock using "just a bunch of devices" that are not synchronized to 
each other. For this mode, the collection of clocks must be synchronized by an 
external program, for example phc2sys(8) in "automatic" mode. 


If we use above option then 

Is it possible to synchronize the multiple phc of interfaces including the 
system clock ?

Thanks,
Raveendra

You can use one ptp4l instance with two network interfaces by setting
the "boundary_clock_jbod" configuration option.

Thanks,
Richard
