[PATCH 0/2] PL1 power limit fixes for ATSM

Previous PL1 power limit implementation assumed that the PL1 limit is
always enabled in HW. However we now find this not to be the case on ATSM
where the PL1 limit is disabled at power up. This requires changes in the
previous PL1 limit implementation.

v2: Dropping Patch 3 (since it is NAK'd by hwmon) so that the first two
    patches can get merged. The first two patches are sufficient to fix the
    main ATSM issue.

Ashutosh Dixit (2):
  drm/i915/hwmon: Replace hwm_field_scale_and_write with
    hwm_power_max_write
  drm/i915/hwmon: Enable PL1 limit when writing limit value to HW
