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 Aapo Vienamo (10): mmc: tegra: Poll for calibration completion mmc: tegra: Set calibration pad voltage reference mmc: tegra: Power on the calibration pad mmc: tegra: Disable card clock during pad calibration dt-bindings: Add Tegra SDHCI pad pdpu offset bindings mmc: tegra: Program pad autocal offsets from dt arm64: dts: tegra186: Add sdmmc pad auto calibration offsets arm64: dts: tegra210: Add sdmmc pad auto calibration offsets mmc: tegra: Perform pad calibration after voltage switch mmc: tegra: Enable pad calibration on Tegra210 and Tegra186 .../bindings/mmc/nvidia,tegra20-sdhci.txt | 34 +++ arch/arm64/boot/dts/nvidia/tegra186.dtsi | 20 ++ arch/arm64/boot/dts/nvidia/tegra210.dtsi | 12 + drivers/mmc/host/sdhci-tegra.c | 280 +++++++++++++++++++-- 4 files changed, 319 insertions(+), 27 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
