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: v2: - Fix grammar in PMC device tree bindings docs - Remove a stray line from tegra sdhci bindings - Cosmetic changes to PMC pinctrl driver - Fix a typo in "soc/tegra: pmc: Implement tegra_io_pad_is_powered()" commit message - Declare mask and value on the same line in tegra_io_pad_is_powered() - Move the call to tegra_sdhci_is_pad_and_regulator_valid() to inside the if condition in tegra_sdhci_reset() - Use usleep_range() in tegra_sdhci_configure_cal_pad() - Move sdhci_writel() out of the enable if-else body in tegra_sdhci_configure_cal_pad() - Add a delay before starting polling in tegra_sdhci_pad_autocalib() - Use usleep_range() in tegra_sdhci_set_tap() - Rename orig_enabled to status in tegra_sdhci_configure_card_clk() - Fix if condition wrapping alignment in tegra_sdhci_set_tap() 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.
