+/** @file
+  Register names for PCH Smbus Device.
+
+  Conventions:
+
+  - Register definition format:
+    Prefix_[GenerationName]_[ComponentName]_SubsystemName_RegisterSpace_RegisterName
+  - Prefix:
+    Definitions beginning with "R_" are registers
+    Definitions beginning with "B_" are bits within registers
+    Definitions beginning with "V_" are meaningful values within the bits
+    Definitions beginning with "S_" are register size
+    Definitions beginning with "N_" are the bit position
+  - [GenerationName]:
+    Three letter acronym of the generation is used (e.g. SKL,KBL,CNL etc.).
+    Register name without GenerationName applies to all generations.
+  - [ComponentName]:
+    This field indicates the component name that the register belongs to (e.g. PCH, SA etc.)
+    Register name without ComponentName applies to all components.
+    Register that is specific to -LP denoted by "_PCH_LP_" in component name.
+  - SubsystemName:
+    This field indicates the subsystem name of the component that the register belongs to
+    (e.g. PCIE, USB, SATA, GPIO, PMC etc.).
+  - RegisterSpace:
+    MEM - MMIO space register of subsystem.
+    IO  - IO space register of subsystem.
+    PCR - Private configuration register of subsystem.
+    CFG - PCI configuration space register of subsystem.
+  - RegisterName:
+    Full register name.
