How do I use the iMX6 watchdog without a 32 kHz clock

I have an iMX6-DL based board where the iMX6 has been implemented without the 32 kHz clock source. (The clock pins are terminated.)

 

I am now trying to implement the watchdog timer but I noticed that the clock on the watchdog is dependent upon the ipg_clk_32k clock in order to drive the watchdog counter.

 

Does this mean that there is no clock to drive the watchdog timer?

 

Is there another clock source that can be used to drive the watchdog hardware?
