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.
Changelog: v2: - Rename the series - Align the register macros - Use readl_poll_timeout() in tegra_sdhci_pad_autocalib() - Move SDHCI_TEGRA_PAD_E_INPUT_OR_E_PWRD define to correc patch - Use !!(reg & SDHCI_CLOCK_CARD_EN) in tegra_sdhci_configure_card_clk() - Add "nvidia," prefix to pad drive strength offset dt props - Read the drive strength properties as u32 instead of u8 - Disable autocalibration if it times out
