| | * | PCI: layerscape: Modify the MSIX to the doorbell modeXiaowei Bao2020-09-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dw_pcie_ep_raise_msix_irq was never called in the exisitng driver before, because the ls1046a platform don't support the MSIX feature and msix_capable was always set to false. Now that add the ls1088a platform with MSIX support, use the doorbell method to support the MSIX feature.

The Artpec6, Intel, and Tegra driver initialize these register fields. Let's move the initialization to the common setup code and drivers just have to provide the value. There's a slight change in that the common clock mode N_FTS field is now initialized. Previously only the Intel driver set this. It's not clear from the code if common clock mode is used in the Artpec6 or Tegra driver. It depends on the DWC configuration. Given the field is not initialized while the others are, it seems unlikely common clock mode is used.

The only platform doing something custom is TI Keystone (surprise!). It does its own mapping of the config space to avoid spliting the config space and never actually uses va_cfg1_base as it has its own config space accessors. With the splitting removed, Keystone can use the default mapping of config space.
