The current cppc acpi driver works with only one pcc subspace id. It maintains and registers only one pcc channel even if the acpi table has different pcc subspace ids. The series tries to address the same by making cppc acpi driver aware of multiple possible pcc subspace ids. Patch 1 : In preparation to share the MAX_PCC_SUBSPACE definition with cppc acpi driver Patch 2 : Make the cppc acpi driver aware of multiple pcc subspace ids.
