13  * peci_temp_read() - read the maximum die temperature from PECI target device
14  * @device: PECI device to which request is going to be sent
17  * It uses GetTemp PECI command.
38  * peci_pcs_read() - read PCS register
39  * @device: PECI device to which request is going to be sent
44  * It uses RdPkgConfig PECI command.
70  * peci_pci_local_read() - read 32-bit memory location using raw address
71  * @device: PECI device to which request is going to be sent
78  * It uses RdPCIConfigLocal PECI command.
105  * peci_ep_pci_local_read() - read 32-bit memory location using raw address
106  * @device: PECI device to which request is going to be sent
114  * Like &peci_pci_local_read, but it uses RdEndpointConfig PECI command.
141  * peci_mmio_read() - read 32-bit memory location using 64-bit bar offset address
142  * @device: PECI device to which request is going to be sent
148  * @address: 64-bit MMIO address
151  * It uses RdEndpointConfig PECI command.
