hwmon: (ads7828) fix Wvoid-pointer-to-enum-cast warning

2023-08-21T13:04:30+00:00

'chip' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

  ads7828.c:142:10: error: cast to smaller integer type 'enum ads7828_chips' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

hwmon: Explicitly include correct DT includes

2023-08-21T13:04:29+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

hwmon: Switch i2c drivers back to use .probe()

2023-06-08T13:41:17+00:00

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.

hwmon: use simple i2c probe function (take 2)

2020-09-23T16:42:40+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 to call i2c_match_id() with the same level of
error-handling (if any) as before.

This patch wraps up the transition for hwmon, with four stragglers not
included in the previous large patch.

hwmon: (ads7828) Fix build warning

2019-04-16T00:19:53+00:00

If CONFIG_OF is not enabled, the following build warning is observed.

drivers/hwmon/ads7828.c:203:34: warning:
	‘ads7828_of_match’ defined but not used

Mark ads7828_of_match as __maybe_unused to fix the problem.

hwmon: (ads7828) Use permission specific SENSOR[_DEVICE]_ATTR variants

2018-12-16T23:13:35+00:00

Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code,
to improve readbility, and to reduce the chance of inconsistencies.

Also replace any remaining S_ in the driver with octal values.

The conversion was done automatically with coccinelle. The semantic patches
and the scripts used to generate this commit log are available at
https://github.com/groeck/coccinelle-patches/hwmon/.

This patch does not introduce functional changes. It was verified by
compiling the old and new files and comparing text and data sizes.

hwmon: (ads7828) Accept optional parameters from device tree

2017-04-02T14:01:53+00:00

Adding the ability for the ads7828 and ads7830 to use device tree to
get optional parameters instead of using platform devices. This allows
people using custom boards to also use the ads7828 in a non-default manner.

hwmon: (ads7828) Add OF device ID table

2017-04-02T14:01:53+00:00

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
