Commit 0580286d0d22 ("arm64: tegra: Add Tegra234 PCIe C4 EP definition")
added the device tree entry "pcie-ep@14160000" for C4 endpoint. However,
it missed pinctrl definition. Without the pinctl definition, the C4
endpoint of Jetson Orin Nano does not work. Add the missing definition.

Hello Tegra architecture maintainers,

any chance that this could get queued up for 6.18-rc1 ?

The device tree node it modifies pcie-ep@14160000 is marked as disabled
by default, so there should be no risk of regressions.


Kind regards,
Niklas
