New Revision: 362392
URL: https://svnweb.freebsd.org/changeset/base/362392
Log:
Adapt ARMADA8k PCIe driver to newly imported 5.7 DT.
- temporarily disable handling with phy, we don't have driver for it yet
- always clear cause for administartive interrupt.
While I'm in, fix style(9) (mainly whitespace).
MFC after: 4 weeks
