If the clock is used to generate the osc_32k, we need to mark as critical. clock-critical has no binding description at the moment but it's defined in linux kernel
bd71847: pmic@4b { ... rohm,reset-snvs-powered;
#clock-cells = <0>; clock-critical = <1>; clocks = <&osc_32k 0>; clock-output-names = "clk-32k-out"; ... }
