[igt-dev] [PATCH i-g-t 0/3] i915/i915_hwmon: General verification of hwmon attributes

Ensure we can read all hwmon attributes. For writable attributes, also
ensure the read value approximately matches the written value, taking the
clamping of writes into account.

v2: Added new patch "lib/igt_sysfs: Make it easier to extend verification
of clamped sysfs attr". No changes to previous patches.
v3: Identical to v2, failed to copy reviewers
v4: Drop the concept of a 'clamped' sysfs attribute, it is not
necessary. All we need is a writable attribute for which the read
values will match the written values for a few points across the range
of all possible values.

Ashutosh Dixit (3):
lib/igt_sysfs: Generic verification of writable sysfs attributes
i915/i915_hwmon: General verification of hwmon attributes
HAX: Add i915_hwmon* to fast-feedback.testlist
