Enable PM_GENERIC_DOMAINS for tegra 64-bit devices. To ensure that devices dependent upon a particular power-domain are only probed when that power domain has been powered up, requires that PM is made mandatory for tegra 64-bit devices and so select this option for tegra as well.

All of a sudden any combination of builds that includes Tegra won't be possible to build without PM support. Adding linux-arm-kernel at lists.infradead.org for visibility.
Agreed, it would be better to add 'depends on PM_GENERIC_DOMAINS' dependencies in the drivers that require it. Arnd
