hwmon: (tmp401) Drop support for TMP461

2021-10-28T02:48:19+00:00

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.

hwmon: cleanup non-bool "valid" data fields

2021-10-12T14:22:41+00:00

We have bool so use it consistently in all the drivers.

The following Coccinelle script was used:

@@
identifier T;
type t = { char, int };
@@
struct T {
...
-	t valid;
+	bool valid;
...
}

@@
identifier v;
@@
(
- v->valid = 0
+ v->valid = false
|
- v->valid = 1
+ v->valid = true
)

followed by sed to fixup the comments:
sed '/bool valid;/{s/!=0/true/;s/zero/false/}'

Few whitespace changes were fixed manually. All modified drivers were
compile-tested.

hwmon: use simple i2c probe function

2020-09-23T16:42:39+00:00

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.

hwmon: (tmp401) use smb word operations instead of 2 smb byte operations

2017-01-10T17:01:32+00:00

tmp401 separately read/wrote high and low bytes of temperature values while
the hardware supports reading/writing those values in one operation. Driver
has been modified to use word operations where possible.

Tested with a tmp432 sensor on a mips64 platform.

hwmon: (tmp401) use permission-specific DEVICE_ATTR variants

2017-01-02T18:19:45+00:00

Use DEVICE_ATTR_RW for read/write attributes. This simplifies the source
code, improves readbility, and reduces the chance of inconsistencies.

The conversion was done automatically using coccinelle. It was validated
by compiling both the old and the new source code and comparing its text,
data, and bss size.

I2C address 0x37 may be used by EEPROMs, which can result in false
positives. Do not attempt to detect a chip at this address.
