regulator/lp3971: vol_map out of bounds in lp3971_{ldo,dcdc}_set_voltage()

2010-02-12T11:39:49+00:00

After `for (val = LDO_VOL_MIN_IDX; val <= LDO_VOL_MAX_IDX; val++)', if no break
occurs, val reaches LDO_VOL_MIN_IDX + 1, which is out of bounds for
ldo45_voltage_map[] and ldo123_voltage_map[].

Similarly BUCK_TARGET_VOL_MAX_IDX + 1 is out of bounds for buck_voltage_map[].

regulator: Fix display of null constraints for regulators

2010-02-12T11:19:57+00:00

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: Specify REGULATOR_CHANGE_STATUS for WM835x LED constraints

2010-02-01T13:52:44+00:00

The WM8350 LED driver needs to be able to enable and disable the
regulators it is using. Previously the core wasn't properly enforcing
status change constraints so the driver was able to function but this
has always been intended to be required.

regulator: wm831x_reg_read() failure unnoticed in wm831x_aldo_get_mode()

2009-12-17T10:27:30+00:00

ret should be signed to notice a failure in wm831x_reg_read().

twl-regulator: Fix reg_disable functionality for 4030 and 6030

2009-12-17T10:27:29+00:00

This change makes sure all regulator group assignments are cleared on
disable call

twl-regulator: Add turnon delay to reg_enable

2009-12-17T10:27:29+00:00

This change implements a basic turnon delay in the regulator enable function
to make it less probable that reg_enable returns before the regulator
output is at target level

twl-regulator: Restore REMAP configuration in regulator probe

2009-12-17T10:27:29+00:00

This change ensures the regulator REMAP register configuration is in a known
state so state transitions will function as intended regardless of
possible bootloader effects on it

twl-regulator: Add turnon-delay and REMAP config to twlreg_info struct

2009-12-17T10:27:29+00:00

This change includes regulator turnon delay values and the REMAP reset
configuration to the twlreg_info struct, since they are basic attributes
of every TWL regulator

twl-regulator: Define critical regulators as always_on

2009-12-17T10:27:28+00:00

Defines VIO, VDD1, VDD2, VPLL1 and VINT* regulators as always_on by default
since they are critical to TWL and its master's functionality and should
be on in all cases where RegFW is used
