Hi all, Update the tegra_sdhci_pad_autocalib() pad drive strength calibration procedure to match the ones specified in the TRMs of the more recent SoCs. This was tested on Tegra186, Tegra210, and Tegra124, although it should not break things older generations either.
This series depends on the "Tegra SDHCI enable 1.8 V signaling on Tegar210 and Tegra186" series posted earlier.
