dt-bindings: Changes for v6.6-rc1

A number of Tegra-specific bindings are converted to json-schema and the
reserved-memory and BPMP bindings get support for Tegra264.

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:

NVIDIA Tegra AHB



Required properties:

- compatible : For Tegra20, must contain "nvidia,tegra20-ahb".  For

  Tegra30, must contain "nvidia,tegra30-ahb".  Otherwise, must contain

  '"nvidia,<chip>-ahb", "nvidia,tegra30-ahb"' where <chip> is tegra124,

  tegra132, or tegra210.

- reg : Should contain 1 register ranges(address and length).  For

  Tegra20, Tegra30, and Tegra114 chips, the value must be <0x6000c004

  0x10c>.  For Tegra124, Tegra132 and Tegra210 chips, the value should

  be be <0x6000c000 0x150>.



Example (for a Tegra20 chip):

	ahb: ahb@6000c004 {

		compatible = "nvidia,tegra20-ahb";

		reg = <0x6000c004 0x10c>; /* AHB Arbitration + Gizmo Controller */

	};

  - "nvidia,tegra210-flowctrl": for Tegra210

- reg: Should contain one register range (address and length)



Example:



	flow-controller@60007000 {

		compatible = "nvidia,tegra20-flowctrl";

		reg = <0x60007000 0x1000>;
