Subject: soc/tegra: Stub out PCIe IRQ workaround on 64-bit ARM
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8582f6d158c8824042432f581d49ef478d5cb238;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

soc/tegra: Stub out PCIe IRQ workaround on 64-bit ARM

The PCIe host controller found on Tegra20 has a hardware bug that causes
PCIe interrupts to get lost when LP2 is enabled. Stub out the workaround
on 64-bit ARM because none of the more recent Tegra SoC generations seem
to have this bug anymore.
