I checked your proposal. If unconditional power on is going to be done for all the registered domains it may happen to register domains for which there are no enabled nodes in device tree and thus the domains to remain on (because the driver enables it under the hood and the genpd core doesn't know about it). With unconditional power on and the current DTSes the following domains remain on after booting with r9a08g045s33-smarc.dtb: - sdhi2 - i2c2 - i2c3 as the domains are registered and powered (while registered) but the nodes are not enabled in DT.

To make it clear: I did not suggest doing an unconditional power-on. I merely suggested moving the conditional power-on from rzg2l_cpg_add_pm_domains() to rzg2l_cpg_pd_setup().
