u5500: keep LDO_H always on

2012-03-19T07:49:27+00:00

The software specification says: "The sub camera is put in standby by setting GPIO_002 (CAM_SUB_PWDN) high and leaving the power supplies on, shutting only one power supply off will result in a leakage current of 1.1mA, Leaving both supplies on results in a leakage current of 15uA". Both supplies here are LDO_H and VIO, and since VIO is always on, keep LDO_H always on too, setting it to low power mode instead of disabling it.

regulator: ab8500: Clean out SoC registers

2012-03-19T07:49:26+00:00

Clean out initialization that is handled by SoC. Regulator settings for Vpll (partly), Vsmps1, Vsmps2, Vsmps3 (partly), Vrf1, Varm, Vape, Vbb, Vmod are cleaned out. They should not be touched by the kernel. This patch removes the possibility to set these register bits as well (change in the driver). If there is a need to set these bits, they should be set during early boot, in e. g. SoC settings.

regulator: ab8500: Remove Vsafe settings

2012-03-19T07:49:26+00:00

The Vsafe regulator should not be handled by kernel, it should be setup before the kernel starts. This patch removes the setting of Vsmsp3Regu.

regulator: ab8500: Remove Vsafe voltage settings

2012-03-19T07:49:26+00:00

The Vsafe regulator should not be handled by the kernel, it should be setup before the kernel starts. This patch removes the voltage settings. Current consumption will increase slightly (rough estimate 25 uA) when the platform is in the low power state because SoC sets a voltage of 0.95 V where the kernel set a voltage of 0.925 V.

regulator: ab8500: Init debug from regulator driver

2012-03-19T07:49:22+00:00

The purpose of this patch is to guarantee that debug (regulator/ab8500-debug.c) will record the regulator registers before they are modified by the driver (regulator/ab8500.c).

regulator: db5500: Correct propagation to power state

2012-03-19T07:49:19+00:00

This patch solves an issue with the power state count (which is used when CPUidle takes the decision to go to sleep). When a db5500 regulator is enabled/disabled, the power state count should only be updated if there is a change in the regulator state. Normally, this error is not visible because the regulator framework will check if the regulator is enabled before enabling. But if the suspend/resume functionality of the regulator framework is activated, there may be calls to enable even if the regulator is already enabled.
