+/** @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.
