Stephen Warren	a3c9454e53	dt: Document Tegra20/30 pinctrl binding ... Define a new binding for the Tegra pin controller, which is capable of defining all aspects of desired pin multiplexing and pin configuration. This is all based on the new common pinctrl bindings. Add Tegra30 binding based on Tegra20 binding. Add some basic stuff that was missing before: * How many and what reg property entries must be provided. * An example.

Stephen Warren	e3f80045e8	dt: Move Tegra20 pin mux binding into new pinctrl directory ... This places the file in the new location for all pin controller bindings. Also, rename the file using the full compatible value for easier avoidance of conflicts between multiple bindings.

Stephen Warren	7a865277fb	dt: pinctrl: Document device tree binding ... The core pin controller bindings define: * The fact that pin controllers expose pin configurations as nodes in device tree. * That the bindings for those pin configuration nodes is defined by the individual pin controller drivers. * A standardized set of properties for client devices to define numbered or named pin configuration states, each referring to some number of the afore-mentioned pin configuration nodes. * That the bindings for the client devices determines the set of numbered or named states that must exist.
