PM_GENERIC_DOMAINS is a bool symbol, so pm_domains.o can never be part
of a module. Is that correct?
Yeah, So this platform_driver does not need to set an owner, it will be
populated by the
driver core.

This include could probably be dropped.
Yeah. As the about said.

+ .data = (void *)&rk3288_pmu,

+};
+MODULE_DEVICE_TABLE(of, rockchip_pm_domain_dt_match);
The MODULE_DEVICE_TABLE() macro will be preprocessed away for built-in
code, according to include/linux/module.h.
So,do you think we should remove it?
wow.....,looks we should remove it.
+static struct platform_driver rockchip_pm_domain_driver = {
+ .probe = rockchip_pm_domain_probe,
+ .driver = {
+ .name = "rockchip-pm-domain",
+ .owner = THIS_MODULE,
According to include/linux/export.h THIS_MODULE is equivalent to NULL
for built-in code. So I think this line is not needed.
Yeah,you are right.
+ .of_match_table = rockchip_pm_domain_dt_match,
+ /*
+ * We can't forcibly eject devices form power domain,
+ * so we can't really remove power domains once they
+ * were added.

Thanks,

Thanks,
