[PATCH 0/5] PCI: uniphier: Add features for UniPhier PCIe host controller

From: Kunihiko Hayashi
Date: Fri May 15 2020 - 00:48:55 EST


This series adds some features for UniPhier PCIe host controller.

- Add support for PME and AER invoked by MSI interrupt
- Add iATU register view support for PCIe version >= 4.80
- Add an error message when failing to get phy driver

This adds a new function called by MSI handler in DesignWare PCIe framework,
that invokes PME and AER funcions to detect the factor from SoC-dependent
registers.
