Subject: [PATCH v2 0/7] platform/x86: intel_pmc_core: Add debugfs entries

Hi,

Tiger Lake platform supports 8 sub-states/low power modes of S0ix. Add
debugfs entries to pmc_core driver to access low power mode registers
and residencies.

Patch 1: Add debugfs entry to access sub-state residencies
Patch 2: Add debugfs entry for low power mode status registers
Patch 3: Refactor the driver by removing redundant code
Patch 4: Remove slp_s0 attributes from tgl_reg_map
Patch 5: Add an additional parameter to pmc_core_lpm_display_map()
Patch 6: Dump low power status registers on an S0ix.y failure
Patch 7: Add debugfs support to access live status registers

Changes since v1:
1) Rebased it on for-next branch to make sure patch series apply
   cleanly.
