Uwe Kleine-König 1975d16786 hwmon: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("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.

When ti,n-factor, ti,beta-compentation are not defined in devicetree,
of_property_read_u32|s32 returns -EINVAL. In this case,
tmp401_init_client should return 0 instead of simply pass ret to its
caller.

Camel Guo bd79021072 hwmon: (tmp401) Add support of three advanced features
tmp401 driver supports TMP401, TMP411 and TMP43X temperature sensors.
According to their datasheet:
- all of them support extended temperature range feature;
- TMP411 and TPM43X support n-factor correction feature;
- TMP43X support beta compensation feature.

In order to support setting them during bootup, this commit reads
ti,extended-range-enable, ti,n-factor and ti,beta-compensation and set
the corresponding registers during probing.

Camel Guo 3481551f03 hwmon: (tmp401) Add OF device ID table
This driver doesn't have of_match_table. This makes the kernel module
tmp401.ko lack alias patterns (e.g: of:N*T*Cti,tmp411) to match DT node
of the supported devices hence this kernel module will not be
automatically loaded.

After adding of_match_table to this driver, the folllowing alias will be
added into tmp401.ko.

Guenter Roeck ff300b71ba hwmon: (tmp401) Hide register write address differences in regmap code
Since we are using regmap access functions to write into chip registers,
we can hide the difference in register write addresses within regmap
code. By doing this we do not need to clear the regmap cache on register
writes, and the high level code does not need to bother about different
read/write register addresses.

Guenter Roeck bcb31e6808 hwmon: (tmp401) Simplify temperature register arrays
The difference between TMP431 and other chips of this series is that the
TMP431 has an additional sensor. The register addresses for other sensors
are the same for all chips. It is therefore unnecessary to maintain two
different arrays for TMP431 and the other chips. Just use the same array
for all chips and add the TMP431 register addresses as third column.

Guenter Roeck 38d9f06c57 hwmon: (tmp401) Drop support for TMP461
TMP461 is almost identical to TMP451, which is already supported by the
lm90 driver. At the same time, unlike other sensors from the TMP401
compatible series, it only supports 8-bit temperature read operations,
and it supports negative temperatures when configured for its default
temperature range, and it supports a temperature offset register.
Supporting this chip in the tmp401 driver adds unnecessary complexity.
Remove its support from this driver and support the chip with the lm90
driver instead.

...
}

@@
identifier v;

(

Few whitespace changes were fixed manually. All modified drivers were

Stephen Kitt 6748703856 hwmon: use simple i2c probe function
Many hwmon drivers don't use the id information provided by the old
i2c probe function, and the remainder can easily be adapted to the new
form ("probe_new") by calling i2c_match_id explicitly.

This avoids scanning the identifier tables during probes.

Drivers which didn't use the id are converted as-is; drivers which did
are modified as follows:

* if the information in i2c_client is sufficient, that's used instead
  (client->name);
* anything else is handled by calling i2c_match_id() with the same
  level of error-handling (if any) as before.

A few drivers aren't included in this patch because they have a
different set of maintainers. They will be covered by other patches.

  several chips added to existing drivers: TPS40400, TPS40422, MTD040,
  MAX34446, ZL9101M, ZL9117M, and LM96080.  Also, added watchdog support
  for SCH56xx, and additional attributes for a couple of drivers."

Axel Lin f0967eea80 hwmon: convert drivers/hwmon/* to use module_i2c_driver()
This patch converts the drivers in drivers/hwmon/* to use the
module_i2c_driver() macro which makes the code smaller and a bit simpler.

Jean Delvare e5e9f44c24 i2c: Drop I2C_CLIENT_INSMOD_2 to 8
These macros simply declare an enum, so drivers might as well declare
it themselves. This puts an end to the arbitrary limit of 8 chip types
per i2c driver.

This adds support for TI's TMP411 sensor chip.

Preliminary support were done by Gabriel Konat, Sander Leget and
Wouter Willems. The chip is compatible with TI's TMP401 sensor
chip. It has additional support for historical minimun/maximum

Hans de Goede ab2b79d5e2 hwmon: (tmp401) Add support for TI's TMP401 sensor chip
This is a new hwmon driver for TI's TMP401 temperature sensor IC. This driver
was written on behalf of an embedded systems vendor under the
Linux driver project.

It has been tested using a TI TMP401 sample attached to a i2c-tiny-usb adapter.
Which was provided by Till Harbaum, many thanks to him for this!
