Sebastian Reichel 88635b6da8 power: supply: ds2780: fix race-condition in bin attribute registration
This is a follow-up patch to the previous one, which fixed a
race-condition during registration of the attribute group.
This fixes the same issue for the binary attributes by adding
them to the properly registered group. As a side effect the
code is further cleaned up.

Sebastian Reichel b10474aafe power: supply: ds2780: fix race-condition in sysfs registration
This registers custom sysfs properties using the native functionality
of the power-supply framework, which cleans up the code a bit and
fixes a race-condition. Before this patch the sysfs attributes were
not properly registered to udev.

Ognjen Galic 285995d15d power: add to_power_supply macro to the API
This patch adds the to_power_supply macro to upcast
a device to a power_supply struct.

This is needed because the same piece of code using
container_of is used in various other places, so we
abstract away such low-level operations via a macro.

Bhumika Goyal 16ac345b15 power: supply: add const to bin_attribute structures
Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file or
device_{remove/create}_bin_file. The corresponding parameters
passed are of type const, so declare the structures to be const.

Done using Coccinelle:

@m disable optional_qualifier@
identifier s;
position p;
@@
static struct bin_attribute s@p={...};

@okay1@
position p;
identifier m.s;
@@
(
sysfs_create_bin_file(...,&s@p,...)
|
sysfs_remove_bin_file(...,&s@p,...)
)

@bad@
position p!={m.p,okay1.p};
identifier m.s;
@@
s@p

@change depends on !bad disable optional_qualifier@
identifier m.s;
@@
static
+const
struct bin_attribute s={...};

Same script was modified for device_{create/remove}_bin_file functions.

Andrew F. Davis de0d6dbdbd w1: Add subsystem kernel public interface
Like other subsystems we should be able to define slave devices outside
of the w1 directory. To do this we move public facing interface
definitions to include/linux/w1.h and rename the internal definition
file to w1_internal.h.

As w1_family.h and w1_int.h contained almost entirely public
driver interface definitions we simply removed these files and
moved the remaining definitions into w1_internal.h.

With this we can now start to move slave devices out of w1/slaves and
into the subsystem based on the function they implement, again like
other drivers.

Sebastian Reichel 8c0984e5a7 power: move power supply drivers to power/supply
This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
