2012-02-10regulator: Fix getting voltage in max8649_enable_time()Axel Lin

2012-02-09regulator: Fix mc13xxx regulator modular build (again)David Miller
Since mc13xxx-regulator-core.c and the actual drivers can get built into seperate modules, you have to export the DT support symbols "mc13xxx_get_num_regulators_dt" and "mc13xxx_parse_regulators_dt" otherwise the allmodconfig build fails on sparc64.

2012-02-09regulator: Complain if a voltage range is specified but can't be usedMark Brown
It doesn't make much sense to specify a range of voltages consumers can use if they haven't been given permission to change the voltage. Log if this happens, probably the user forgot to specify CHANGE_VOLTAGE. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@ti.com>
2012-02-09regulator: Don't add the function name to pr_fmtMark Brown
Liam pointed out via IM that since we now use the pure function name for all regulator logging a lot of the messages such as those logging the constraints are getting a bit noisy due to the implementation detail that is the function name: print_constraints: VDDARM: 1000 <--> 1300 mV at 1300 mV at 0 mA In discussion it seemed like the best thing was to just drop the pr_fmt and clarify individual log messages where there is an issue otherwise we get into silly things like renaming the functions to suit the logging. This is mostly an issue as we have a moderate amount of non-error logging in the boot sequence to aid debug if something goes wrong since regulator misconfiguration can kill the system pretty quickly.

2012-02-02regulator: Kill s5m8767_get_reg_id functionAxel Lin
Calling s5m8767_get_reg_id() is exactly the same as calling rdev_get_id(). It is pointless to add s5m8767_get_reg_id() function. Use rdev_get_id() directly and remove s5m8767_get_reg_id() function.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator This fixes an integration issue with the regulator device tree bindings which shook out in -rc. The bindings were overly enthusiatic when deciding to set a voltage on a regulator and would try to set zero volts on an unconfigured regulator which isn't supported. * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: regulator: Set apply_uV only when min and max voltages are defined

2012-01-25regulator: Reverse the disable sequence in regulator_bulk_disable()Sylwester Nawrocki
Often there is a need for disabling a set of regulators in order opposite to the enable order. Currently the function regulator_bulk_disable() walks list of regulators in same order as regulator_bulk_enable(). This may cause trouble, especially for devices with mixed analogue and digital circuits. So reverse the disabling sequence of regulator_bulk_disable(). While at it, also correct the comment.
