Description
Different EEPROM files are required to achieve best performance depending on the power amplifier (PA) and low noise amplifier (LNA) type which, as far as I understand, can be ePAeLNA, iPAiLNA, iPAeLNA or ePAiLNA, where e and i stand for internal and external respectively.
In case no EEPROM is available via NVMEM, we need to load the correct EEPROM file from the file system. So, provided, that there is no better way, we would probably need a property in device-tree to specify the PA/LNA type so that the fitting EEPROM file can be loaded.

Research direction
No source files or tests are named. Start by tracing the existing EEPROM loading path, including NVMEM access and filesystem fallback, then inspect how device-tree properties could represent the PA/LNA variants; done means the matching EEPROM is selected when NVMEM is unavailable.
