This series consist of several parts: changes requried for 1.8 V signaling and pad control, pad calibration, and tuning. Following earlies patch sets have been merged into this larger set: "Tegra PMC pinctrl pad configuration", "Tegra SDHCI enable 1.8 V signaling on Tegar210 and Tegra186", "Tegra SDHCI update the padautocal procedure". Also the patches for enabling SDHCI tuning are added. Changelog: v1: - Probe the regulator voltage capabilities to determine whether pinctrl is needed in tegra_sdhci_r eset - Don't remove tegra_sdhci_voltage_switch() - Use dev_warn() in tegra_sdhci_init_pinctrl_info() - Don't change start_signal_voltage_switch callback if pinctrl info invalid - Only call udelay(1) on enable in tegra_sdhci_configure_cal_pad() - Add nvidia, prefix to pad autocal offset dt props in the example See the original patch sets for earlier changelogs.
