reboot: arm: change reboot_mode to use enum reboot_mode

2013-07-09T17:33:29+00:00

Preparing to move the parsing of reboot= to generic kernel code forces
the change in reboot_mode handling to use the enum.

charger-manager: Fix regulator_get() return check

2013-06-29T01:37:03+00:00

This patch fixes return value checking of regulator_get() in
charger-manager driver. The API, regulator_get(), returns ERR_PTR() when
it fails to get regulator with given name, not NULL.

charger-manager: Fix a bug when it unregisters notifier block of extcon

2013-06-29T01:35:49+00:00

This patch prevents NULL pointer error cauesed by unregistering
unregistered exton notifier block. At the probing time of charger manager,
it tries to remove extcon notifier block when it fails to initialize them.
It has to be applied for only registered one. Otherwise, it'd make kernel
panic. To make it work right, it checks extcon_specific_cable_nb's
extcon_dev node. If extcon cable notifier block was registered
successfully, it has proper extcon_dev pointer if not so it has NULL
pointer.

tps65090-charger: Add dt node to power_supply

2013-06-29T01:20:58+00:00

Passing in the dt node for this charger enables the logic in the core to
lookup this device, to see if it is supplying another power_supply,
through dt.

sbs-battery: Add dt to power_supply struct

2013-06-29T01:20:56+00:00

By passing in the dt node of this device, we enable the logic for linking
power_supplies together from dt. This is specified by adding a
"power-supplies" property with a phandle to the charger for a given
supply.

Enable this logic now for the sbs-battery driver.

power_supply: Add of_node_put to fix refcount

2013-06-29T01:20:54+00:00

of_parse_phandle increments the refcount for a dt node before returning
it. Add of_node_put where needed to properly decrement the refcount when
we are done using a given node.

power/reset: Make the vexpress driver optional on arm and arm64

2013-06-22T00:33:30+00:00

The driver can be used on either arm or arm64 platforms, but
the latter doesn't have any platform-specific configuration
options, so it must be possible to manually enable the driver.

PM / AVS: SmartReflex: use devm_* API to initialize SmartReflex

2013-06-10T17:50:48+00:00

Use of of devm_* API for resource allocation provides benefits such
as auto handling of resource free. This reduces possibility have
memory leaks in case of wrong error handling. All direct release
calls should be removed to avoid races.

PM / AVS: SmartReflex: use omap_sr * for enable/disable interface

2013-06-10T17:46:18+00:00

SmartReflex driver interface is natively divided to two parts:

- external SmartReflex interface
- interface between SmartReflex driver and SmartReflex Class

Functions which belong to AVS class interface can use
struct omap_sr* instead of struct voltatedomain*, to provide a
direct connection between SR driver and SR class. This allows
us to optimize and not do additional lookups where none is
required.

sr_enable() and sr_disable() are interface functions between
SR driver and SR class. They are typically used by Class driver
to enable/disable SmartReflex hardware module.
Now they take struct omap_sr* as input parameter.
