Add YAML schema for the device tree bindings for DSI

Signed-off-by: Krishna Manikandan <mkrishn@codeaurora.org>

Changes in v1:
    - Separate dsi controller bindings to a separate patch (Stephen Boyd)
    - Merge dsi-common-controller.yaml and dsi-controller-main.yaml to
      a single file (Stephen Boyd)
    - Drop supply entries and definitions from properties (Stephen Boyd)
    - Modify phy-names property for dsi controller (Stephen Boyd)
    - Remove boolean from description (Stephen Boyd)
    - Drop pinctrl properties as they are standard entries (Stephen Boyd)
    - Modify the description for ports property and keep the reference
      to the generic binding where this is defined (Stephen Boyd)
    - Add description to clock names (Stephen Boyd)
    - Correct the indendation (Stephen Boyd)
    - Drop the label for display dt nodes and correct the node
      name (Stephen Boyd)

Changes in v2:
    - Drop maxItems for clock (Stephen Boyd)
    - Drop qcom,mdss-mdp-transfer-time-us as it is not used in upstream
      dt file (Stephen Boyd)
    - Keep child node directly under soc node (Stephen Boyd)
    - Drop qcom,sync-dual-dsi as it is not used in upstream dt

Changes in v3:
    - Add description for register property (Stephen Boyd)

Changes in v4:
    - Add maxItems for phys property (Stephen Boyd)
    - Add maxItems for reg property (Stephen Boyd)
    - Add reference for data-lanes property (Stephen Boyd)
    - Remove soc from example (Stephen Boyd)

Changes in v5:
    - Modify title and description (Stephen Boyd)
    - Add required properties for ports node (Stephen Boyd)
    - Add data-lanes in the example (Stephen Boyd)
    - Drop qcom,master-dsi property (Stephen Boyd)

Changes in v6:
    - Add required properties for port@0, port@1 and corresponding
      endpoints (Stephen Boyd)
    - Add address-cells and size-cells for ports (Stephen Boyd)
    - Use additionalProperties instead of unevaluatedProperties (Stephen Boyd)

Changes in v7:
    - Add reference for ports and data-lanes (Rob Herring)
    - Add maxItems and minItems for data-lanes (Rob Herring)

You can drop 'reg'.

Don't need this.

This is not where the $ref goes. Please look at other users.

Don't redescribe common properties. If you have something special about 
this device, then say it.

Drop. Already covered by the common schema.

Needs a $ref to video-interfaces.yaml.

Drop

Last 2 are covered by the common schema.

-
-DSI Controller:
-Required properties:
-- compatible:
-  * "qcom,mdss-dsi-ctrl"
-- reg: Physical base address and length of the registers of controller
-- reg-names: The names of register regions. The following regions are required:
-  * "dsi_ctrl"
-- interrupts: The interrupt signal from the DSI block.
-- power-domains: Should be <&mmcc MDSS_GDSC>.
-- clocks: Phandles to device clocks.
-- clock-names: the following clocks are required:
-  * "mdp_core"
-  * "iface"
-  * "bus"
-  * "core_mmss"
-  * "byte"
-  * "pixel"
-  * "core"
-  For DSIv2, we need an additional clock:
-   * "src"
-  For DSI6G v2.0 onwards, we need also need the clock:
-   * "byte_intf"
-- assigned-clocks: Parents of "byte" and "pixel" for the given platform.
-- assigned-clock-parents: The Byte clock and Pixel clock PLL outputs provided
-  by a DSI PHY block. See [1] for details on clock bindings.
-- vdd-supply: phandle to vdd regulator device node
-- vddio-supply: phandle to vdd-io regulator device node
-- vdda-supply: phandle to vdda regulator device node
-- phys: phandle to DSI PHY device node
-- phy-names: the name of the corresponding PHY device
-- syscon-sfpb: A phandle to mmss_sfpb syscon node (only for DSIv2)
-- ports: Contains 2 DSI controller ports as child nodes. Each port contains
-  an endpoint subnode as defined in [2] and [3].
-
-Optional properties:
-- panel@0: Node of panel connected to this DSI controller.
-  See files in [4] for each supported panel.
-- qcom,dual-dsi-mode: Boolean value indicating if the DSI controller is
-  driving a panel which needs 2 DSI links.
-- qcom,master-dsi: Boolean value indicating if the DSI controller is driving
-  the master link of the 2-DSI panel.
-- qcom,sync-dual-dsi: Boolean value indicating if the DSI controller is
-  driving a 2-DSI panel whose 2 links need receive command simultaneously.
-- pinctrl-names: the pin control state names; should contain "default"
-- pinctrl-0: the default pinctrl state (active)
-- pinctrl-n: the "sleep" pinctrl state
-- ports: contains DSI controller input and output ports as children, each
-  containing one endpoint subnode.
-
-  DSI Endpoint properties:
-  - remote-endpoint: For port@0, set to phandle of the connected panel/bridge's
-    input endpoint. For port@1, set to the MDP interface output. See [2] for
-    device graph info.
-
-  - data-lanes: this describes how the physical DSI data lanes are mapped
-    to the logical lanes on the given platform. The value contained in
-    index n describes what physical lane is mapped to the logical lane n
-    (DATAn, where n lies between 0 and 3). The clock lane position is fixed
-    and can't be changed. Hence, they aren't a part of the DT bindings. See
-    [3] for more info on the data-lanes property.
-
-    For example:
-
-    data-lanes = <3 0 1 2>;
-
-    The above mapping describes that the logical data lane DATA0 is mapped to
-    the physical data lane DATA3, logical DATA1 to physical DATA0, logic DATA2
-    to phys DATA1 and logic DATA3 to phys DATA2.
-
-    There are only a limited number of physical to logical mappings possible:
-    <0 1 2 3>
-    <1 2 3 0>
-    <2 3 0 1>
-    <3 0 1 2>
-    <0 3 2 1>
-    <1 0 3 2>
-    <2 1 0 3>
-    <3 2 1 0>
-
-DSI PHY:
-Required properties:
-- compatible: Could be the following
-  * "qcom,dsi-phy-28nm-hpm"
-  * "qcom,dsi-phy-28nm-lp"
-  * "qcom,dsi-phy-20nm"
-  * "qcom,dsi-phy-28nm-8960"
-  * "qcom,dsi-phy-14nm"
-  * "qcom,dsi-phy-14nm-660"
-  * "qcom,dsi-phy-10nm"
-  * "qcom,dsi-phy-10nm-8998"
-  * "qcom,dsi-phy-7nm"
-  * "qcom,dsi-phy-7nm-8150"
-- reg: Physical base address and length of the registers of PLL, PHY. Some
-  revisions require the PHY regulator base address, whereas others require the
-  PHY lane base address. See below for each PHY revision.
-- reg-names: The names of register regions. The following regions are required:
-  For DSI 28nm HPM/LP/8960 PHYs and 20nm PHY:
-  * "dsi_pll"
-  * "dsi_phy"
-  * "dsi_phy_regulator"
-  For DSI 14nm, 10nm and 7nm PHYs:
-  * "dsi_pll"
-  * "dsi_phy"
-  * "dsi_phy_lane"
-- clock-cells: Must be 1. The DSI PHY block acts as a clock provider, creating
-  2 clocks: A byte clock (index 0), and a pixel clock (index 1).
-- power-domains: Should be <&mmcc MDSS_GDSC>.
-- clocks: Phandles to device clocks. See [1] for details on clock bindings.
-- clock-names: the following clocks are required:
-  * "iface"
-  * "ref" (only required for new DTS files/entries)
-  For 28nm HPM/LP, 28nm 8960 PHYs:
-- vddio-supply: phandle to vdd-io regulator device node
-  For 20nm PHY:
-- vddio-supply: phandle to vdd-io regulator device node
-- vcca-supply: phandle to vcca regulator device node
-  For 14nm PHY:
-- vcca-supply: phandle to vcca regulator device node
-  For 10nm and 7nm PHY:
-- vdds-supply: phandle to vdds regulator device node
-
-Optional properties:
-- qcom,dsi-phy-regulator-ldo-mode: Boolean value indicating if the LDO mode PHY
-  regulator is wanted.
-- qcom,mdss-mdp-transfer-time-us:	Specifies the dsi transfer time for command mode
-					panels in microseconds. Driver uses this number to adjust
-					the clock rate according to the expected transfer time.
-					Increasing this value would slow down the mdp processing
-					and can result in slower performance.
-					Decreasing this value can speed up the mdp processing,
-					but this can also impact power consumption.
-					As a rule this time should not be higher than the time
-					that would be expected with the processing at the
-					dsi link rate since anyways this would be the maximum
-					transfer time that could be achieved.
-					If ping pong split is enabled, this time should not be higher
-					than two times the dsi link rate time.
-					If the property is not specified, then the default value is 14000 us.
