[PATCH 2/3] platform/x86: intel_pmc_core: Fix TigerLake power gating status map

From: David E. Box
Date: Tue Oct 06 2020 - 18:47:20 EST


From: Gayatri Kammela <gayatri.kammela@xxxxxxxxx>

TigerLake's LPM power gating status register has errors in the bit-to-name
mapping as well as with the marked reserved bits according to the actual
implementation. Hence, update the right bit-to-name mapping and the
reserved bits in accordance with actual implementation.
