@brief
Register names for PCH High Definition Audio device.
Conventions:
- Prefixes:
Definitions beginning with "R_" are registers
Definitions beginning with "B_" are bits within registers
Definitions beginning with "V_" are meaningful values of bits within the registers
Definitions beginning with "S_" are register sizes
Definitions beginning with "N_" are the bit position
- In general, PCH registers are denoted by "_PCH_" in register names
- Registers / bits that are different between PCH generations are denoted by
"_PCH_<generation_name>_" in register/bit names. e.g., "_PCH_VLV_"
- Registers / bits that are different between SKUs are denoted by "_<SKU_name>"
at the end of the register/bit names
- Registers / bits of new devices introduced in a PCH generation will be just named
as "_PCH_" without <generation_name> inserted.
