Subject: [PATCH v6 02/10] dt-bindings: display: tegra: Convert to json-schema
From: Thierry Reding <treding@...dia.com>
Convert the Tegra host1x controller bindings from the free-form text
format to json-schema.
This also adds the missing display-hub DT bindings that were not
previously documented.

-NVIDIA Tegra MIPI pad calibration controller
-
-Required properties:
-- compatible: "nvidia,tegra<chip>-mipi"
-- reg: Physical base address and length of the controller's registers.
-- 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:
- - mipi-cal
-- #nvidia,mipi-calibrate-cells: Should be 1. The cell is a bitmask of the pads
- that need to be calibrated for a given device.
-
-User nodes need to contain an nvidia,mipi-calibrate property that has a
-phandle to refer to the calibration controller node and a bitmask of the pads
-that need to be calibrated.
-
-Example:
-
- mipi: mipi@...e3000 {
- compatible = "nvidia,tegra114-mipi";
- reg = <0x700e3000 0x100>;
- clocks = <&tegra_car TEGRA114_CLK_MIPI_CAL>;
- clock-names = "mipi-cal";
- #nvidia,mipi-calibrate-cells = <1>;

-Device tree binding for NVIDIA Tegra DPAUX pad controller
-========================================================
-
-The Tegra Display Port Auxiliary (DPAUX) pad controller manages two pins
-which can be assigned to either the DPAUX channel or to an I2C
-controller.
-
-This document defines the device-specific binding for the DPAUX pad
-controller. Refer to pinctrl-bindings.txt in this directory for generic
-information about pin controller device tree bindings. Please refer to
-the binding document ../display/tegra/nvidia,tegra20-host1x.txt for more
-details on the DPAUX binding.
-
-Pin muxing:
------------
-
-Child nodes contain the pinmux configurations following the conventions
-from the pinctrl-bindings.txt document.
-
-Since only three configurations are possible, only three child nodes are
-needed to describe the pin mux'ing options for the DPAUX pads.
-Furthermore, given that the pad functions are only applicable to a
-single set of pads, the child nodes only need to describe the pad group
-the functions are being applied to rather than the individual pads.
-
-Required properties:
-- groups: Must be "dpaux-io"
-- function: Must be either "aux", "i2c" or "off".
-
-Example:
---------
-
- dpaux@...c0000 {
- ...
-
- state_dpaux_aux: pinmux-aux {
- groups = "dpaux-io";
- function = "aux";
- };
-
- state_dpaux_i2c: pinmux-i2c {
- groups = "dpaux-io";
- function = "i2c";
- };
-
- state_dpaux_off: pinmux-off {
- groups = "dpaux-io";
- function = "off";
- };
- };
-
- ...
-
- i2c@...0d100 {
- ...
- pinctrl-0 = <&state_dpaux_i2c>;
- pinctrl-1 = <&state_dpaux_off>;
- pinctrl-names = "default", "idle";
- };
