[RFC v2 0/2] Add support for time DT property in TCPM

Posted by Amit Sunil Dhamne 2 months, 1 week ago

USB PD specification defines a bunch of timers that can have a range of
acceptable values instead of specific values. These values have to be
tuned based on the platform. However, TCPM currently sets them to a
default value without providing a mechanism to set platform specific
values.

This patchset adds new DT properties per timer to allow users to define
platform specific values.

Changes compared to v1:
  - Defined new properties per timer that we are interested in rather
    than defining a single pd-timers u32 array property.
  - Better description of the timer properties.
  - Since subject has changed, adding link for previous patchset for
    posterity:
