[PATCH 3/5] dt-bindings: arm: tegra: nvec: Convert to json-schema

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

Convert the NVIDIA embedded controller bindings from the free-form text
format to json-schema.

Marc,

you authored this binding a long time ago, which makes the default
license for this GPL-2.0. However, the preference is for DT bindings to
be dual-licensed under the more permissive GPL-2.0-only OR BSD-2-Clause
as done in this patch. Do you have any objections to relicensing?

Thierry

-NVIDIA compliant embedded controller
-
-Required properties:
-- compatible : should be "nvidia,nvec".
-- reg : the iomem of the i2c slave controller
-- interrupts : the interrupt line of the i2c slave controller
-- clock-frequency : the frequency of the i2c bus
-- gpios : the gpio used for ec request
-- slave-addr: the i2c address of the slave controller
-- clocks : Must contain an entry for each entry in clock-names.
-  See ../clocks/clock-bindings.txt for details.
-- clock-names : Must include the following entries:
-  Tegra20/Tegra30:
-  - div-clk
-  - fast-clk
-  Tegra114:
-  - div-clk
-- resets : Must contain an entry for each entry in reset-names.
-  See ../reset/reset.txt for details.
-- reset-names : Must include the following entries:
-  - i2c
