i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Rename ChargeOption macros to match the others for ChargeCurrent and
ChargeVoltage and also separate the command & masks macros from the bits of
interest macros for each command. This macro doesn't introduce any
functional change, only code re-org.

Few drivers implement remove call-back only for ensuring a delayed
work gets cancelled prior driver removal. Clean-up these by switching
to use devm_delayed_work_autocancel() instead.
This change is compile-tested only. All testing is appreciated.

The driver include <linux/gpio.h> but actually only use
<linux/gpio/consumer.h> which is includes below. Drop the
surplus legacy header include.

i2c_smbus commands handle the correct byte order for smbus transactions
internally. This will currently result in incorrect operation on big

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

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.

So what if there is a status_gpio specified? bq24735_charger_is_present()
do have a working fallback for the case of no status_gpio.
Simplify this by not special casing setups w/o status_gpio, folding
two consecutive if-blocks in the process.

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.

bq24735_enable_charging() needs to call bq24735_config_charging(),
which is something to change later, this is just a preparatory patch.

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.
This also fixes that specific issue.

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.
