I don't think this works, the ti,default-parent property is only 
supported for clock nodes (at least I didn't quickly find anything from 
your clocksource driver that would handle this.) You should do something 
like this:

&timer1_fck {
	ti,default-parent = <&sys_clkin_ck>;
};

&timer2_fck {
	ti,default-parent = <&sys_clkin_ck>;
};
