Series arm64: qcom: sa8775p: add support for EP PCIe |

Commit Message

Mrinmay Sarkar Oct. 31, 2023, 5:11 a.m. UTC 
  Add support for Qualcomm Snapdragon SA8775P SoC to the EPF driver.
Reusing DID (0x0306) for SA8775P and it supports HDMA. Currently,
it has no fixed PCI class, so it is being advertised as
"PCI_CLASS_OTHERS".

You should state why you are reusing the "PID" and whether it is going to be
updated in the future or not.
