Subject: [PATCH v3 11/12] ARM: tegra: trimslice: Initialize PCIe from DT
Date: Wed,  3 Apr 2013 16:45:17 +0200	[thread overview]
Message-ID: <1365000318-28256-12-git-send-email-thierry.reding@avionic-design.de> (raw)
In-Reply-To: <1365000318-28256-1-git-send-email-thierry.reding@avionic-design.de>

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 <thierry.reding@avionic-design.de>

Changes in v2:
- add missing dummy regulator nodes by Stephen Warren
- rename port 0 DT node and disable unused port 1
