[00/10] PCI: DWC/Keystone: MSI configuration cleanup

Message

Kishon Vijay Abraham I Dec. 19, 2018, 12:41 p.m. UTC

This series tries to address the comments discussed in [1] w.r.t
removing Keystone specific callbacks defined in dw_pcie_host_ops.

This series also tries to cleanup the Keystone interrupt handling
part.

This series is created on top of
git://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/pci.git
pci/dwc-msi

Tested on K2G (had to use out of tree SERDES patches). Also tested on
dra7xx to make sure there are no regressions.
