If anyone has any objections, please let me know. ------------------ From: Jon Hunter [ Upstream commit d19a86d584e04191cdab7ced24d7ed791075697a ] Tegra194 and Tegra234 PCIe EP controllers have 64K alignment restriction for the inbound ATU. Set the endpoint inbound ATU alignment to 64kB in the Tegra194 PCIe driver.
