This migrates isp1704 driver from old GPIO API to new descriptor
based GPIO API and drops useless platform data as a side-effect.
Migration is simple, since all mainline users are DT based and
DT API does not change. Out of tree users of the platform data
need to migrate to gpiod_lookup_table as described here:

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

When the BQ27xxx driver was originally written the w1 subsystem only
allowed device drivers for w1 attached devices to live in the w1
subsystem. Kernel driver subsystems expect that the driver for a device
live in the directory of the subsystem for which it implements
functionality, not in the directory of the bus that it is attached. To
work around this, the BQ27xxx driver was implemented as a platform device
driver and the interface driver would instantiate this device from within
the w1 directory, then pass a w1 read callback as platform data.
As we can now have the w1 interface driver in the power/supply directory
(like we do already with the i2c interface driver) we can remove this
middle-layer platform driver.

Previously there was no way to configure these chips in the event that the

For chips with RAM data memory (and also those with flash/NVM data memory
if CONFIG_BATTERY_BQ27XXX_DT_UPDATES_NVM is defined and the user has not
set module param dt_monitored_battery_updates_nvm=0) we now call
power_supply_get_battery_info(), check its values, and write battery
properties to chip data memory if there is a dm_regs table for the chip.

Userspace prefers the driver having a status property over having to guess
itself. Specifically this will properly make the GNOME3 UI (and likely
others) properly show discharging / charging / full status, instead
of always showing discharging as status.
Note that in the case there is no charger driver supplying the max17042,
then a status of unknown will get returned. At least upower treats
this the same as not having a status attribute, so in this case nothing
changes from a userspace pov.

Some x86 machines use a max17047 fuel-gauge and x86 might be missing
platform_data if not provided by SFI.
This commit adds default platform_data as fallback option so that the
driver can work on boards where no platform_data is provided.
Since not all boards have a thermistor hooked up, set temp_min to 0 and
change the health checks from temp <= temp_min to temp < temp_min to
not trigger on such boards (where temp reads 0).

There where still a few lingering references to pdata after commit
power: supply: sbs-battery: simplify DT parsing.
Remove pdata from struct·sbs_info and conditional checks to ser if this
was set from the i2c read / write functions.
Instead of call max in each function for incrementing poll_retry_count
do it once in the probe function.
Fixup null pointer dereference in to pdata in sbs_external_power_changed.
Change retry counts to u32 to avoid need for max.

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.

Switch to using new gpio_desc interface and devm gpio get calls to
automatically manage gpio resource. Use gpiod_get_value which handles
active high / low calls.
If gpio_detect is set then force loading of the driver as it is
reasonable to assume that the battery may not be present.
Update the is_present flag immediately in the IRQ.
Remove legacy gpio specification from platform data.

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.
