[PATCH V3] PCI: dwc: tegra194: Broaden architecture dependency

From: Vidya Sagar
Date: Thu Apr 17 2025 - 03:47:33 EST


Replace ARCH_TEGRA_194_SOC dependency with a more generic ARCH_TEGRA
check, allowing the PCIe controller to be built on Tegra platforms
beyond Tegra194. Additionally, ensure compatibility by requiring
ARM64 or COMPILE_TEST.
