Subject: [PATCH v2 1/5] dt-bindings: phy: tegra: Add Tegra186 support

From: Thierry Reding <treding@...dia.com>

Extend the bindings to cover the set of features found in Tegra186. Note
that, technically, there are four more supplies connected to the XUSB
pad controller (DVDD_PEX, DVDD_PEX_PLL, HVDD_PEX and HVDD_PEX_PLL), but
the power sequencing requirements of Tegra186 require these to be under
the control of the PMIC.
