@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.
