| 12 | @brief\r | |
| 13 | Register names for PCH High Definition Audio device.\r | |
| 14 | \r | |
| 15 | Conventions:\r | |
| 16 | \r | |
| 17 | - Prefixes:\r | |
| 18 | Definitions beginning with "R_" are registers\r | |
| 19 | Definitions beginning with "B_" are bits within registers\r | |
| 20 | Definitions beginning with "V_" are meaningful values of bits within the registers\r | |
| 21 | Definitions beginning with "S_" are register sizes\r | |
| 22 | Definitions beginning with "N_" are the bit position\r | |
| 23 | - In general, PCH registers are denoted by "_PCH_" in register names\r | |
| 24 | - Registers / bits that are different between PCH generations are denoted by\r | |
| 25 | "_PCH_<generation_name>_" in register/bit names. e.g., "_PCH_VLV_"\r | |
| 26 | - Registers / bits that are different between SKUs are denoted by "_<SKU_name>"\r | |
| 27 | at the end of the register/bit names\r | |
| 28 | - Registers / bits of new devices introduced in a PCH generation will be just named\r | |
| 29 | as "_PCH_" without <generation_name> inserted.\r | |
