iio: potentiometer: ad5272: Correct polarity of reset

2020-12-03T19:32:42+00:00

The driver should assert reset by setting the gpio high, and
then release it by setting it the gpio low. This allows the
device tree (or other hardware definition) to specify how the
gpio is configured.

For example as open drain or push-pull depending on the
connected hardware.

iio:potentiometer:mcp4531: Drop of_match_ptr and CONFIG_OF protections.

2020-09-21T17:41:27+00:00

These prevent use of this driver with ACPI via PRP0001 and are
an example of an anti pattern I'm trying to remove from IIO.
Hence drop them from this driver.

Also switch to device_get_match_data() from of_ variant and adjust
headers to reflect the change.

iio:potentiometer:mcp4131: Drop of_match_ptr and use generic fw interfaces.

2020-09-21T17:41:26+00:00

This change allows the use of the driver with ACPI via PRP0001
and remove an example of an anti pattern I'm trying to remove from IIO.
Also adjust includes to reflect this change.

iio:potentiometer:max5481: Drop invalid ACPI binding.

2020-09-21T17:41:26+00:00

Given that an ACPI binding must start with 3 or 4 capitals,
this cannot represent a valid binding.

It seems unlikely anything out there is using it.

Whilst this driver has an ACPI binding, it is not of a form
that is valid under ACPI so will be dropped shortly.

Also switch to device_get_match_data() and switch headers.

Replace HTTP links with HTTPS ones: drivers/iio

2020-07-13T14:05:59+00:00

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
          If both the HTTP and HTTPS versions
          return 200 OK and serve the same content:
            Replace HTTP with HTTPS.
