All supported Renesas ARM64 SoCs have clock and power domains. To ensure proper operation of on-SoC modules, module clocks must be ungated, and power domains must be powered up when needed. Currently the user can choose to build a kernel with power management enabled or disabled: - If CONFIG_PM=y, power domains and/or module clocks are handled dynamically by Runtime PM and the generic power domain. - If CONFIG_PM=n, power domains are assumed to be powered up by reset state or by the boot loader, and module clocks are handled by the legacy clock domain on driver (un)bind. The latter is implemented using a platform bus notifier, which applies not only to all on-SoC devices, but to all platform devices present in the system. To remove the dependency on implicit assumptions, and to get rid of the peculiarities of the legacy clock domain, enable CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS unconditionally.
