Arnd Bergmann 0ad2185dcb soc: sunxi: select CONFIG_PM
Selecting CONFIG_PM_GENERIC_DOMAINS without CONFIG_PM leads to a
build failure:

WARNING: unmet direct dependencies detected for PM_GENERIC_DOMAINS

  Selected by [y]:

Unfortunately platforms are inconsistent between using 'select PM'
and 'depends on PM' here. CONFIG_PM is a user-visible symbol, so
in principle we should be using 'depends on', but on the other hand
using 'select' here is more common among drivers/soc. Go with the
majority for now, as this has a smaller risk of introducing circular
dependencies. We may need to clean this up for consistency later.

Say y here to enable the SRAM controller support. This

Say y to enable the PPU power domain driver. This saves power
when certain peripherals, such as the video engine, are idle.
