e47bfe803b regulator: Factor out functions to work with regulator_internal
Internally we only have a struct regulator_internal, so factor
out regulator_enable_internal and regulator_disable_internal
functions which can be called from regulator internal code.

f72725e352 regulator: add bcm2835 driver
this will allow to handle IP power automatically and not at board level

Mainline kernel need this as they do not have the regulator driver support

as some IP such as USB are not power on at boot

b3265685f7 sandbox: allow "make ARCH=sandbox allyesconfig"
Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.

This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.

2eb002699c regulator: fixed: add always-on property
Support the "regulator-always-on" property for fixed regulators.
The regulator gets enabled on probe and subsequent disable calls are
ignored.

485788954c Add initial regulator support
Provide minimal regulator support. Only supported operations are enabling
and disabling regulators. Association of devices with their regulators is
limited to devicetree only. If regulator support is disabled the API expands
to static inline stubs so consumers can still use the API.
