[PATCH v2 00/10] Tegra SDHCI enable 1.8 V signaling on Tegar210 and Tegra186

[Aapo Vienamo]

Hi all,

Reconfigure pad voltages as part of mmc voltage switching on
controllers with adjustable voltages. Allow for reconfiguration of the
signaling voltage of SDMMC1 on Tegra210 P2597 and fix SDMMC4 signaling
voltage regulator configuration on Tegra210 P2180.

This series depends on the "Tegra PMC pinctrl pad configuration" series posted
earlier.

Changelog:
v2:
	- Change the pinctrl bindings commit title
	- Use IS_ERR in tegra_sdhci_init_pinctrl_info()
	- Add nvidia,only-1-8-v property
	- Disable UHS modes in case the pad and regulator configuration
	  is invalid
