3  * Driver for the Intel Broxton PMC
10  * The PMC (Power Management Controller) running on the ARC processor
13  * turn sends messages between the IA and the PMC.
52  * BIOS does not create an ACPI device for each PMC function, but
74  * intel_pmc_gcr_read64() - Read a 64-bit PMC GCR register
75  * @pmc: PMC device pointer
