[PATCH v2 09/10] ARM: tegra: harmony: Initialize PCIe from DT

From: Thierry Reding <hidden>
Date: 2012-06-11 15:05:17
Also in: linux-arm-kernel, linux-pci, linux-tegra
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

Possibly related (same subject, not in this thread)

With the device tree support in place, probe the PCIe controller from
the device tree and remove the corresponding workaround in the board
file.

Signed-off-by: Thierry Reding <redacted>
