regulator: Fix display of null constraints for regulators

2010-02-23T15:37:49+00:00

commit 973e9a2795b3b41d8408a0bb6f87b783c5efc88a upstream.

If the regulator constraints are empty and there is no voltage
reported then nothing will be added to the text displayed for the
constraints, leading to random stack data being printed. This is
unlikely to happen for practical regulators since most will at
least report a voltage but should still be fixed.

REGULATOR Handle positive returncode from enable

2009-09-22T12:32:43+00:00

This makes _regulator_enable() properly handle the case where
a regulator is already on when you try to enable it. Currently
it will erroneously handle positive return values as an error.

regulator: regulator_enable() permission checking

2009-09-22T12:32:41+00:00

The regulator_enable() code wasn't actually checking that the
machine constraints had given permission to enable the regulator.
Add code to do that, but only if the regulator is not already on
due to something like always_on or being left on at startup since
in those cases there's no physical change being introduced and the
constraint wouldn't make any sense.

Also add matching code for disable(). We need to do less there since
either regulator_enable() should have succeeded first or the board
setup makes no sense.

regulator: Push locking for regulator_is_enabled() out

2009-09-22T12:32:40+00:00

Allows use by more of the internal regulator API code.

regulator: Fix support for deviceless supply mappings

2009-09-22T12:32:39+00:00

The patch to add support for looking up consumers by device name
had the side effect of causing us to require a device which is
at best premature since at least cpufreq still operates outside
the device model. Remove that requirement.

regulator: Warn when unregistering an in-use regulator

We're probably going to start oopsing fairly soon after this happens.

regulator: Add regulator voltage range check API

2009-09-22T12:32:38+00:00

Simplify checking of support for voltage ranges by providing an API which
wraps the existing count and list operations.
