regulator: s2mps11: Fix dw_mmc failure on Gear 2

2015-01-16T14:59:56+00:00

commit 1222d8fe578cd28a6c7f5e4e6c6b664c56abfdc0 upstream.

Invalid buck4 configuration for linear mapping of voltage in S2MPS14
regulators caused boot failure on Gear 2 (dw_mmc-exynos):

[    3.569137] EXT4-fs (mmcblk0p15): mounted filesystem with ordered data mode. Opts: (null)
[    3.571716] VFS: Mounted root (ext4 filesystem) readonly on device 179:15.
[    3.629842] mmcblk0: error -110 sending status command, retrying
[    3.630244] mmcblk0: error -110 sending status command, retrying
[    3.636292] mmcblk0: error -110 sending status command, aborting

Buck4 voltage regulator has different minimal voltage value than other
bucks. Commit merging multiple regulator description macros caused to
use linear_min_sel from buck[1235] regulators as value for buck4. This
lead to lower voltage of buck4 than required.

Output of the buck4 is used internally as power source for
LDO{3,4,7,11,19,20,21,23}. On Gear 2 board LDO11 is used as MMC
regulator (V_EMMC_1.8V).

regulator: anatop: Set default voltage selector for vddpu

2015-01-08T18:30:17+00:00

commit fe08be3ec8672ed92b3ed1b85810df9fa0f98931 upstream.

The code reads the default voltage selector from its register. If the
bootloader disables the regulator, the default voltage selector will be
0 which results in faulty behaviour of this regulator driver.

This patch sets a default voltage selector for vddpu if it is not set in
the register.

regulator: s2mpa01: zero-initialize regulator match table array

2014-11-03T15:56:16+00:00

The struct of_regulator_match rmatch[] is declared as a non-static local
variable so the structure members are not auto-initialized.

Initialize the array at declaration time to avoid the structure members
values to be indeterminate and have sane defaults instead.

regulator: max77693: Fix use of uninitialized regulator config

2014-11-03T14:36:02+00:00

Driver allocated on stack struct regulator_config but didn't initialize
it fully. Few fields (driver_data, ena_gpio) were left untouched. This
lead to using random ena_gpio values as GPIOs for max77693 regulators.

On occasion these values could match real GPIO numbers leading to
interfering with other drivers and to unsuccessful enable/disable of
regulator.
