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.

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
