You probably no longer need to map any clocks here as this is now a child of the interconnect target module managed by ti-sysc driver. I have not checked but probably l4ls_gclk is same as clocks = <&l4ls_clkctrl AM3_L4LS_EPWMSS0_CLKCTRL 0> already managed by ti-sysc. If so, then just using runtime PM calls in any of the child device drivers will keep it enabled. If l4ls_gclk is a separate functional clock, then it still needs to be managed by the child device driver directly. Regards, Tony
