If anyone has any objections, please let me know. ------------------ From: Haotien Hsu commit 7be54870e9bf5ed0b4fe2a23b41a630527882de5 upstream. Periodic calibration updates (~10µs) may overlap with transfers when PCIe NVMe SSD, LPDDR, and USB2 devices operate simultaneously, causing crosstalk on Tegra234 devices. Hence disable periodic calibration updates and make this a one-time calibration.
