Commit Message

Sumeet Pawnikar May 5, 2022, 5 p.m. UTC 
Add high frequency impedance notification support under DPTF.
This returns high frequency impedance value that can be obtained
from battery fuel gauge whenever there is change over a threshold.
Also, corrected the typo from IMPEDANCED_CHNGED to IMPEDANCE_CHANGED.

v1-->v2 : Addressed review comment recevied from Srinivas Pandruvada to add
          corrected the spelling from IMPEDANCED_CHNGED to IMPEDANCE_CHANGED
          under commit message.
