Subject: ARM: tegra: trimslice: Initialize PCIe from DT
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1798efda3cbc7f658a685e7ace2f5ad4bf1ae238;p=linux-beck.git

ARM: tegra: trimslice: Initialize PCIe from DT

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