Are any of these boot-on?
Yes, these are used wcn6855-pmu：
vddio-supply = <&vreg_conn_pa>;
vddpmu-supply = <&vreg_conn_1p8>;
What i meant is, whether these regulators are enabled at boot
time (i.e. without software intervention). If that's the case,
`regulator-boot-on;` should be added
No need regulator-boot-on, it was triggered by the
software(pci_pwrctl_pwrseq_driver).
