twl-regulator: Define critical regulators as always_on · 205e5cd3

Juha Keski-Saari authored Dec 16, 2009

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

regulator: mc13783-regulator: correct the probing time. · 735eb93a

Alberto Panizzo authored Dec 14, 2009

When the mc13783-regulator driver is built in kernel, probing it during
the regulator subsystem initialisation result in a fault.

That is because regulator subsystem is planned to be initialised very early
in the boot process, before the mfd subsystem initialisation.

The mc12783-regulator probing process need to access to the mc13783-core
functionality to read/write mc13783 registers and so must be called after
the mc13783-core driver initialisation.

The way to do this is to let the kernel probe the mc13783-regulator driver when
mc13783-core register his regulator subdevice.

regulator: Fix unbalanced disables/enables in regulator_bulk_{enable,disable} error path · eb143ac1

Lars-Peter Clausen authored Dec 15, 2009

Currently it is possible for regulator_bulk_{enable,disable} operations to
generate unbalanced regulator_{disable,enable} calls in its error path.
In case of an error only those regulators of the bulk operation which actually
had been enabled/disabled should get their original state restored.

drivers/regulator: use PTR_ERR to get error code · d662fc82

Julia Lawall authored Nov 21, 2009

IS_ERR returns only 1 or 0.  The callsite of setup_regulators expects a
negative integer in an error case.  Thus, PTR_ERR has to be used to extract
it.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression E,E1;
@@

*E = IS_ERR(...)
 ... when != E = E1
*return E;

regulator/mc13783: various cleanups · a10099bc

Uwe Kleine-König authored Nov 10, 2009

- define needed registers and bits in the driver
- properly namespace functions and structs
- fix locking as required by patch
  "mfd/mc13783: near complete rewrite"
- use platform_data as provided by "mfd/mc13783: near complete rewrite"
  instead of accessing struct mc13783
- struct mc13783_regulator_priv.desc is (and was) unused and so can go
  away
- use cpp magic to initialize mc13783_regulators
- bring MODULE_LICENSE in sync with actual copyright
- minor style fixes

This allows not including mc13783-private.h which I intend to remove
soon.

regulator/mc13783: rename source file to match other drivers · b4b90c65

Uwe Kleine-König authored Nov 10, 2009

One annoying thing about the old name was that the module was just
called mc13783 which caused wrong expectations (at least for me).

Fix some AB3100 regulator issues · 176f45b9

Linus Walleij authored Oct 28, 2009

LDO D (this magic was not needed), remove an unnecessary (!) error
check and really unregister the regulators when the module is
unloaded.
