+Optional properties for Tegra210, Tegra186 and Tegra194:
 - pinctrl-names, pinctrl-0, pinctrl-1 : Specify pad voltage
   configurations. Valid pinctrl-names are "sdmmc-3v3" and "sdmmc-1v8"
   for controllers supporting multiple voltage levels. The order of names
   should correspond to the pin configuration states in pinctrl-0 and
   pinctrl-1.
+- pinctrl-names : "sdmmc-3v3-drv" and "sdmmc-1v8-drv" are applicable for
+  Tegra210 where pad config registers are in the pinmux register domain
+  for pull-up-strength and pull-down-strength values configuration when
+  using pads at 3V3 and 1V8 levels.
 - nvidia,only-1-8-v : The presence of this property indicates that the
   controller operates at a 1.8 V fixed I/O voltage.
