This patch removes the w1 slave driver that used to register the w1 family
and instanciate a platform device at runtime. The code now lives in the
supply driver instead to avoid that level of indirection.
The old device name "ds2760-battery.0" is preserved, so userspace
applications can access the same virtual device nodes as before.
Note that because the w1 core does not currently have a framework for
suspend/resume, the driver now registers a PM notifier callback.

We did have sporadic problems in the pinctrl framework during boot
where a pin group name unexpectedly became NULL leading to a NULL
dereference in strcmp.
Detailled analysis of the failing cases did reveal that there were
two devm allocated objects close to each other. The second one was
the affected group_desc in pinmux and the first one was the
psy_desc->properties buffer of the gab driver.
Review of the gab code showed that the address calculation for
one memcpy() is wrong. It does
properties + sizeof(type) * index
but C is defined to do the index multiplication already for
pointer + integer additions. Hence the factor was applied twice
and the memcpy() does write outside of the properties buffer.
Sometimes it happened to be the pinctrl and triggered the strcmp(NULL).
Anyways, it is overkill to use a memcpy() here instead of a simple
assignment, which is easier to read and has less risk for wrong
address calculations. So we change code to a simple assignment.
If we initialize the index to the first free location, we can even
remove the local variable 'properties'.
This bug seems to exist right from the beginning in 3.7-rc1 in

getnstimeofday64() is deprecated in favor of the ktime_get() family.
The direct replacement would be ktime_get_real_ts64(), but we only need
the seconds value, and it seems better to use boottime than real time
to avoid unexpected behavior with a concurrent settimeofday().
ktime_get_seconds() might also work, but it seems better to use
boottime than monotonic time since I assume that the charging
process continues during suspend.

Vexpress platforms provide two different restart handlers: SYS_REBOOT
that restart the entire system, while DB_RESET only restarts the
daughter board containing the CPU. DB_RESET is overridden by SYS_REBOOT
if it exists.
notifier_chain_register used in register_restart_handler by design
relies on notifiers to be registered once only, however vexpress restart
notifier can get registered twice. When this happen it corrupts list
of notifiers, as result some notifiers can be not called on proper
event, traverse on list can be cycled forever, and second unregister
can access already freed memory.
So far, since this was the only restart handler in the system, no issue
was observed even if the same notifier was registered twice. However
commit 6c5c0d48b6 ("watchdog: sp805: add restart handler") added
support for SP805 restart handlers and since the system under test
contains two vexpress restart and two SP805 watchdog instances, it was
observed that during the boot traversing the restart handler list looped
forever as there's a cycle in that list resulting in boot hang.
This patch fixes the issues by ensuring that the notifier is installed
only once.

This driver was originally submitted for the TI BQ20Z75 battery IC
(commit a7640bfa10 ("power_supply: Add driver for TI BQ20Z75 gas gauge
IC")) and later renamed to express generic SBS support. While it's
mostly true that this driver implemented a standard SBS command set, it
takes liberties with the REG_MANUFACTURER_DATA register. This register
is specified in the SBS spec, but it doesn't make any mention of what
its actual contents are.
We've sort of noticed this optionality previously, with commit
17c6d3979e ("sbs-battery: make writes to ManufacturerAccess
optional"), where we found that some batteries NAK writes to this
register.
What this really means is that so far, we've just been lucky that most
batteries have either been compatible with the TI chip, or else at least
haven't reported highly-unexpected values.
For instance, one battery I have here seems to report either 0x0000 or
0x0100 to the MANUFACTURER_ACCESS_STATUS command -- while this seems to
match either Wake Up (bits[11:8] = 0000b) or Normal Discharge
(bits[11:8] = 0001b) status for the TI part [1], they don't seem to
actually correspond to real states (for instance, I never see 0101b =
Charge, even when charging).
On other batteries, I'm getting apparently random data in return, which
means that occasionally, we interpret this as "battery not present" or
"battery is not healthy".
All in all, it seems to be a really bad idea to make assumptions about
REG_MANUFACTURER_DATA, unless we already know what battery we're using.
Therefore, this patch reimplements the "present" and "health" checks to
the following on most SBS batteries:
1. HEALTH: report "unknown" -- I couldn't find a standard SBS command
that gives us much useful here
2. PRESENT: just send a REG_STATUS command; if it succeeds, then the
battery is present
Also, we stop sending MANUFACTURER_ACCESS_SLEEP to non-TI parts. I have
no proof that this is useful and supported.
If someone explicitly provided a 'ti,bq20z75' compatible property, then
we continue to use the existing TI command behaviors, and we effectively
revert commit 17c6d3979e ("sbs-battery: make writes to
ManufacturerAccess optional") to again make these commands required.

To allow users of the power supply framework to be hw description
agnostic, this commit adds the ability to pass a fwnode pointer,
via the power_supply_config structure, to the initialisation code
of the core, instead of explicitly specifying of_ndoe. If that
fwnode pointer is provided then it will automatically resolve down
to of_node on platforms which support it, otherwise it will be NULL.
In the future, when ACPI support is added, this can be modified to
accommodate ACPI without the need to change calling code which
already provides the fwnode handle in this manner.

We should get drvdata from struct device directly. Going via
platform_device is an unneeded step back and forth.

This device is software similar to the BQ27426 except it has
different data memory offsets. Add support here.

The power-off call is done in a context that must be able to sleep, so
use gpiod_set_value_cansleep instead of the atomic gpiod_set_value call.
This fixes a kernel warning at shutdown when the gpio is controlled
through an IO expander for example.

This commit adds the 'usb_type' property to represent USB supplies
which can report a number of different types based on a connection
event.
Examples of this already exist in drivers whereby the existing 'type'
property is updated, based on an event, to represent what was
connected (e.g. USB, USB_DCP, USB_ACA, ...). Current implementations
however don't show all supported connectable types, so this knowledge
has to be exlicitly known for each driver that supports this.
The 'usb_type' property is intended to fill this void and show users
all possible USB types supported by a driver. The property, when read,
shows all available types for the driver, and the one currently chosen
is highlighted/bracketed. It is expected that the 'type' property
would then just show the top-level type 'USB', and this would be
static.
Currently the 'usb_type' enum contains all of the USB variant types
that exist for the 'type' enum at this time, and in addition has
SDP and PPS types. The mirroring is intentional so as to not impact
existing usage of the 'type' property.

Currently there's no error checking of this parameter in the
registration function and it's blindly added to psy class and
subsequently used as is. For example if this is NULL the call
to psy_register_thermal() will try to dereference the pointer
thus causing a kernel dump.
This commit updates the registration code to add some basic
checks on the desc pointer validity, name, and presence of
properties.

This release brings up a new platform based on the old ARM9 core: the
Nuvoton NPCM is used as a baseboard management controller, competing
with the better known ASpeed AST2xx series.
Another important change is the addition of ARMv7-A based chips
in mach-stm32. The older parts in this platform are ARMv7-M based
microcontrollers, now they are expanding to general-purpose workloads.
The other changes are the usual defconfig updates to enable additional
drivers, lesser bugfixes. The largest updates as often are the ongoing
OMAP cleanups, but we also have a number of changes for the older
PXA and davinci platforms this time.
For the Renesas shmobile/r-car platform, some new infrastructure
is needed to make the watchdog work correctly.
Supporting Multiprocessing on Allwinner A80 required a significant
amount of new code, but is not doing anything unexpected.
