[BISECTED, REGRESSION] v4.7: Display lost on Kirkwood/OpenRD Client

From: Aaro Koskinen
Date: Wed Aug 10 2016 - 17:59:11 EST


Hi,

When upgrading from v4.6 --> v4.7, I lost the display/framebuffer on
OpenRD-Client (the only pcie device on the board).

Bisection points to:

eb13cf8345e94a02e9872ca3e909596a5ddb5f90 is the first bad commit
commit eb13cf8345e94a02e9872ca3e909596a5ddb5f90
Author: Andrew Lunn <andrew@xxxxxxx>
Date: Sun Apr 3 04:03:47 2016 +0200

ARM: dts: kirkwood: Fixup pcie DT warnings

PCIe has a range property, so the unit name should contain an address.
Make use of the label to enable individual PCIe busses. Also, fixup
the synology dtsi file which added a label pcie2 rather than using the
existing pcie1 label.

Signed-off-by: Andrew Lunn <andrew@xxxxxxx>

Any ideas how to get display working again?
