2014-06-09regulator: mc13xxx: Remove unused field "hi_bit"Alexander Shiyan1-1/+0
Field "hi_bit" is not used anywhere in the driver. This patch removes this excess field. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-04-28regulator: mc13xxx: Add warning of incorrect names of regulatorsAlexander Shiyan1-2/+2
This patch adds a warning about incorrect regulators instead of printing the names of non-information message about the wrong amount. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Mark Brown <broonie@sirena.org.uk>
2013-01-27regulator: mc13892: sanity check num_regulators parsed vs. registeredMatt Sealey1-2/+2
Imagine a situation where a device tree has a few regulators in an appropriate node: regulators { sw1 { .. }; vvideo { .. }; : vfake { .. }; vtypo { .. }; }; In the above example, the node name "vfake" is an attempt to match a regulator name inside the driver which just so happens to not exist. The node name "vtypo" represents an accidental typographical error in a regulator name which may have been introduced to a device tree. In these cases, the number of regulators the mc13892 driver thinks it has does not match the number of regulators it parsed and registered. Since it will go over this array based on this number, it will actually re-register regulator "0" (which happens to be SW1) over and over again until it reaches the number, resulting in messages on the kernel log such as these: SW1: at 1100 mV VVIDEO: at 2775mV : SW1: at 1100 mV SW1: at 1100 mV .. up to that number of "mismatched" regulators. Nobody using DT can/will consume these regulators, so it should not be possible for it to cause any real regulator problems or driver breakages, but it is an easy thing to miss in a kernel log and is an immediate indication of a problem with the device tree authoring. This patch effectively sanity checks the number of counted children of the regulators node vs. the number that actually matched driver names, and sets the appropriate num_regulators value. It also gives a little warning for device tree authors that they MAY have screwed something up, such that this patch does not hide the device tree authoring problem.

2012-08-28regulator: mc13xxx: Remove get_voltage implementation for single voltage ↵Axel Lin1-1/+0
regulators This is not required after commit f7df20ec "regulator: core: Use list_voltage() to read single voltage regulators" Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-07-20regulator: mc13xxx: Remove extern function declaration for mc13xxx_sw_regulatorAxel Lin1-1/+0
This function does not exist, remove the extern function declaration. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-19regulator: mc13xxx: Remove mc13xxx_sw_regulator_is_enabled functionAxel Lin1-1/+0
If .is_enabled callback is not implemented, regulator core assumes that the regulator is always on. Thus we don't need mc13xxx_sw_regulator_is_enabled function. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2012-04-02regulator: Convert mc13xxx regulator drivers to set_voltage_selAxel Lin1-2/+0
Convert mc13892_sw_regulator_ops and mc13xxx_regulator_ops to set_voltage_sel. mc13xxx_get_best_voltage_index function is not used now, remove it. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2011-12-22regulator: mc13892: remove the unnecessary prefix from regulator nameShawn Guo1-3/+3
It's not really necessary to add a prefix 'MC13892__' for each mc13892 regulator name, since the chip must have been identified as mc13892 when we look at the regulator name. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
