Peter Rosin de4fb05142 power: supply: bq24735: bring down the noise level
If there is no ti,ac-detect-gpios configured, it is normal to
have failed reads of the options register. So, hold back on the
log spamming.

Peter Rosin dbff4c8eaa power: supply: bq24735: allow polling even if there is no ac-detect gpio
It is possible to verify AC adapter presence via a register read, without
any physical connection to the ACOK pin on the charger. Allow this.

Hans de Goede 577b1f06e2 power: supply: axp288_charger: Use one notifier_block per extcon cable
Prior to this commit the code was using 1 notifier_block for all
types of charger cable, this is incorrect as the notifier_block
becomes part of a linked-list and now the same notifier_block
is part of 3 linked lists.

This commit fixes this by using a separate nb per extcon cable.

Note this happened to work fine sofar because axp288_charger was the only
listener, so when added to each of the 3 notifier chains, the next pointer
in the nb would be set to 0, so we've 3 heads pointing to the same nb,
with its next pointing to NULL. But as soon as we mix in a second extcon
consumer things will go boom.

Deal with the charger type changing without a vbus-disconnect being
reported in between the 2 charger type states:

-Do not return from axp288_charger_extcon_evt_worker early in this case

-Make calling axp288_charger_enable_charger with the same value as before
 a nop, to avoid the need for the caller to check this
-Do no do a dev_err when axp288_charger_enable_charger returns an error,
 axp288_charger_enable_charger already returns an error itself
-Disable the charger before changing the charge-current setting (nop if
 vbus was seen as disconnected before the change)

Hans de Goede 7508f44129 power: supply: axp288_charger: Actually get and use the USB_HOST extcon device
Nothing was setting info->otg.cable, so the extcon_get_cable_state_
calls on it would always return -EINVAL.

This commit fixes this by actually setting info->otg.cable using the new
extcon_get_extcon_dev_by_cable_id function.

This commit also makes failing to register the extcon notifier for the
USB_HOST cable an error rather then a warning, because we MUST have this
notfier to properly disable the VBUS path when in host mode so that we're
not drawing current from the 5V boost converter which is supplying power
to the otg port when in host mode.

Peter Rosin a07bea32c6 power: supply: bq24735: configure the charger as part of enabling it
During probe, it makes no sense to take care to first not issue any
i2c commands to verify if the connected part really is a bq24735, to
later simply fail the probe in the next step when trying to configure
the charger. So, delay configuration of the charging parameters until
the charger is accessible (i.e. when the AC adapter is present) as
part of enabling the charging.

This also fixes the rather serious issue that the charging parameters
are lost when the AC adapter is disconnected.

TPS65217 has two charger interrupts - AC and USB power status change.

Interrupt number in the TPS65217 driver data:
  IRQ number is only used on requesting the interrupt, so no need to keep
  it inside the driver data.

Interrupt handler:
  Check not only AC but also USB charger status.
  In both cases, enable charging operation.

Interrupt request:
  If an interrupt number is invalid, then use legacy polling thread.
  Otherwise, create IRQ threads to handle AC and USB charger event.

Hans de Goede 888f97435a power: supply: axp288_fuel_gauge: Drop platform_data dependency
When the axp288_faul_gauge driver was originally merged, it was
merged with a dependency on some other driver providing platform
data for it.

However the battery-data-framework which should provide that data
never got merged, resulting in x86 tablets / laptops with an axp288
having no working battery monitor, as before this commit the driver
would simply return -ENODEV if there is no platform data.

This commit removes the dependency on the platform_data instead
checking that the firmware has initialized the fuel-gauge and
reading the info back from the pmic.

What is missing from the read-back info is the table to map raw adc
values to temperature, so this commit drops the temperature and
temperature limits properties. The min voltage, charge design and
model name info is also missing. Note that none of these are really
important for userspace to have.

All other functionality is preserved and actually made available
by this commit.

Guenter Roeck 17c6d3979e sbs-battery: make writes to ManufacturerAccess optional
According to the Smart Battery Data Specification, the use
of ManufacturerAcess (register 0x0) is implementation-defined.
It appears that some batteries use writes to this register
in order to implement certain functionality, but others may
simply NAK all writes to it. As a result, write failures to
ManufacturerAccess should not be used as an indicator of
battery presence, nor as a failure to enter sleep mode.

The failed write access was seen with SANYO AP13J3K.

Arnd Bergmann 9edeaada19 power: supply: sbs-battery: simplify DT parsing
After the change to use the gpio descriptor interface, we get a warning if
-Wmaybe-uninitialized is added back to the build flags (it is currently
disabled:

drivers/power/supply/sbs-battery.c: In function 'sbs_probe':
drivers/power/supply/sbs-battery.c:760:28: error: 'pdata' may be used uninitialized in this function [-Werror=maybe-uninitialized]

The problem is that if neither the DT properties nor a platform_data
pointer are provided, the chip->pdata pointer gets set to an uninitialized
value.

Looking at the code some more, I found that the sbs_of_populate_pdata
function is more complex than necessary and has confusing calling
conventions of possibly returning a valid pointer, a NULL pointer
or an ERR_PTR pointer (in addition to the uninitialized pointer).

To fix all of that, this gets rid of the chip->pdata pointer and
simply moves the two integers into the sbs_info structure. This
makes it much clearer from reading sbs_probe() what the precedence
of the three possible values are (pdata, DT, hardcoded defaults)
and completely avoids the #ifdef CONFIG_OF guards as
of_property_read_u32() gets replaced with a compile-time stub
when that is disabled, and returns an error if passed a NULL of_node
pointer.

Paul Kocialkowski c65a8b5112 power: supply: bq24735-charger: Request status GPIO with initial input setup
This requests the status GPIO with initial input setup. It is required
to read the GPIO status at probe time and thus correctly avoid sending
I2C messages when AC is not plugged.

When requesting the GPIO without initial input setup, it always reads 0
which causes probe to fail as it assumes the charger is connected, sends
I2C messages and fails.

While at it, this switches the driver over to gpiod API.

When the charger is missing (disconnected), it is safe to assume that
the charger chip is no charging.

This is especially relevant when a status GPIO is present and the
charger is getting disconnected. bq24735_charger_is_charging will be
triggered due to the interrupt then, it will attempt to read whether it
is charging through i2c, which will fail as the charger is disconnected.

Bhaktipriya Shridhar b732ace40a power: ds2760_battery: Remove deprecated create_singlethread_workqueue
alloc_ordered_workqueue() with WQ_MEM_RECLAIM set replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion.

The workqueue "monitor_wqueue" is used to monitor the battery
status. It has been identity converted.

It queues multiple work items viz &di->monitor_work,
&di->set_charged_work, which require execution ordering.
Hence, alloc_workqueue has been used to replace the
deprecated create_singlethread_workqueue instance.

WQ_MEM_RECLAIM flag has been set to ensure forward progress under

Linus Torvalds 6f888fe31d ARM: SoC cleanups for v4.8
The cleanup branch keeps going down in size as we've completed a lot of
 the major legacy platform removals and conversions.
 
 A handful of changes this time around, some of the themes or larger sets are:
 
  - A bunch of i.MX cleanups around platform detection, init call cleanups
  - Misc fixes of missing/implicit includes
  - Removal of ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

Andy Yan 4fcd504edb power: reset: add reboot mode driver
This driver parses the reboot commands like "reboot bootloader"
and "reboot recovery" to get a boot mode described in the
device tree , then call the write interfae to store the boot
mode in some place like special register or sram, which can
be read by the bootloader after system reboot, then the bootloader
can take different action according to the mode stored.

This is commonly used on Android based devices, in order to
reboot the device into fastboot or recovery mode.

Rhyland Klein e380538529 power_supply: fix return value of get_property
power_supply_get_property() should ideally return -EAGAIN if it is
called while the power_supply is being registered. There was no way
previously to determine if use_cnt == 0 meant that the power_supply
wasn't fully registered yet, or if it had already been unregistered.

Add a new boolean to the power_supply struct to simply show if
registration is completed. Lastly, modify the check in
power_supply_show_property() to also ignore -EAGAIN when so it
doesn't complain about not returning the property.

Chris Lapa cbf9077e58 max8903: cleans up confusing relationship between dc_valid, dok and dcm.
The max8903_charger.h file indicated that dcm and dok were not optional
when dc_valid is set.

It makes sense to have dok as a compulsory pin when dc_valid is given.
However dcm can be optionally wired to a fixed level especially when the
circuit is configured for dc power exclusively.

The previous implementation already allowed for this somewhat, however no
error was given if dok wasn't given whilst dc_valid was.

The new implementation enforces dok presence when dc_valid is given. Whilst
allowing dcm to be optional.

Driver was trying to use drv_data in property get handler. However drv_data
was not set, so it caused NULL pointer dereference. This patch properly
sets drv_data during probe by power_supply_config parameter, so the
property get handler works as desired.

Rhyland Klein 5bc28b93a3 power_supply: power_supply_read_temp only if use_cnt > 0
Change power_supply_read_temp() to use power_supply_get_property()
so that it will check the use_cnt and ensure it is > 0. The use_cnt
will be incremented at the end of __power_supply_register, so this
will block to case where get_property can be called before the supply
is fully registered. This fixes the issue show in the stack below:

IO-domain handling is part of the general register files, so should live
under the grf directly. This change allows the grf to be a simple-mfd and
the io-domains fetching the syscon regmap from that parent-node.

The old binding is of course preserved, though deprecated.

POWER_SUPPLY_STATUS_NOT_CHARGING is used for AC connected, but
battery not charging (e.g. because battery temperature is out
of acceptable range).

When battery is charging near dry and BATTERY_FULL_DISCHARGED is set,
it is wrong to set as POWER_SUPPLY_STATUS_NOT_CHARGING.
Just use BATTERY_DISCHARGING to decide the power supply status is
discharging or charging.

Sama5d2 SoC has a completely new shutdown controller with new features and
register layout. It thus makes sense to add a new driver for this new

This driver is Device Tree only and handles events from the wake-up pin and
the RTC.
As the register layout may change in the future, so some values are encoded
in a configuration structure.

     resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).

   - Fix for the ACPI backend of the generic device properties API to
     make it parse non-device (data node only) children of an ACPI
     device correctly (Irina Tirdea).

   - Fixes for the handling of global suspend flags (introduced in 4.4)
     during hibernation and resume from it (Lukas Wunner).

   - Support for obtaining configuration information from Device Trees
     in the PM clocks framework (Jon Hunter).

   - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
     King, Geert Uytterhoeven)"

David Wu f447671b9e PM / AVS: rockchip-io: add io selectors and supplies for rk3399
This adds the necessary data for handling io voltage domains on the rk3399.
As interesting tidbit, the rk3399 contains two separate iodomain areas.
One in the regular General Register Files (GRF) and one in PMUGRF in the
pmu power domain.

Linus Torvalds 814a2bf957 Merge branch 'akpm' (patches from Andrew)
Merge second patch-bomb from Andrew Morton:

 - a couple of hotfixes

 - the rest of MM

 - a new timer slack control in procfs

 - a couple of procfs fixes

 - a few misc things

 - some printk tweaks

 - lib/ updates, notably to radix-tree.

 - add my and Nick Piggin's old userspace radix-tree test harness to
   tools/testing/radix-tree/.  Matthew said it was a godsend during the
   radix-tree work he did.

 - a few code-size improvements, switching to __always_inline where gcc
   screwed up.

 - partially implement character sets in sscanf
