In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch adds the
fsl,scu.yaml in the firmware bindings folder. This one is only for
the main SCU node. The old txt file will be removed only after all
the child nodes have been properly switch to yaml.

+
+description: System Controller Device Node
+ The System Controller Firmware (SCFW) is a low-level system function
+ which runs on a dedicated Cortex-M core to provide power, clock, and
+ resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
+ (QM, QP), and i.MX8QX (QXP, DX).
+ The AP communicates with the SC using a multi-ported MU module found
+ in the LSIO subsystem. The current definition of this MU module provides
+ 5 remote AP connections to the SC to support up to 5 execution environments
+ (TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
+ with the LSIO DSC IP bus. The SC firmware will communicate with this MU
+ using the MSI bus.

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'thermal' child node of the SCU main node.

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents

Now that all the child nodes have been properly documented in the
yaml files, within their proper subystems, we can drop the fsl,scu.txt.

-NXP i.MX System Controller Firmware (SCFW)
---------------------------------------------------------------------
-
-The System Controller Firmware (SCFW) is a low-level system function
-which runs on a dedicated Cortex-M core to provide power, clock, and
-resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
-(QM, QP), and i.MX8QX (QXP, DX).
-
-The AP communicates with the SC using a multi-ported MU module found
-in the LSIO subsystem. The current definition of this MU module provides
-5 remote AP connections to the SC to support up to 5 execution environments
-(TZ, HV, standard Linux, etc.). The SC side of this MU module interfaces
-with the LSIO DSC IP bus. The SC firmware will communicate with this MU
-using the MSI bus.
-
-System Controller Device Node:
-============================================================
-
-The scu node with the following properties shall be under the /firmware/ node.
-
-Required properties:
--------------------
-- compatible: should be "fsl,imx-scu".
-- mbox-names: should include "tx0", "tx1", "tx2", "tx3",
- "rx0", "rx1", "rx2", "rx3";
- include "gip3" if want to support general MU interrupt.
-- mboxes: List of phandle of 4 MU channels for tx, 4 MU channels for
- rx, and 1 optional MU channel for general interrupt.
- All MU channels must be in the same MU instance.
- Cross instances are not allowed. The MU instance can only
- be one of LSIO MU0~M4 for imx8qxp and imx8qm. Users need
- to make sure use the one which is not conflict with other
- execution environments. e.g. ATF.
- Note:
- Channel 0 must be "tx0" or "rx0".
- Channel 1 must be "tx1" or "rx1".
- Channel 2 must be "tx2" or "rx2".
- Channel 3 must be "tx3" or "rx3".
- General interrupt rx channel must be "gip3".
- e.g.
- mboxes = <&lsio_mu1 0 0
- &lsio_mu1 0 1
- &lsio_mu1 0 2
- &lsio_mu1 0 3
- &lsio_mu1 1 0
- &lsio_mu1 1 1
- &lsio_mu1 1 2
- &lsio_mu1 1 3
- &lsio_mu1 3 3>;
- See Documentation/devicetree/bindings/mailbox/fsl,mu.yaml
- for detailed mailbox binding.
-
-Note: Each mu which supports general interrupt should have an alias correctly
-numbered in "aliases" node.
-e.g.
-aliases {
- mu1 = &lsio_mu1;
-};
-
-i.MX SCU Client Device Node:
-============================================================
-
-Client nodes are maintained as children of the relevant IMX-SCU device node.
-
-Power domain bindings based on SCU Message Protocol
-------------------------------------------------------------
-
-This binding for the SCU power domain providers uses the generic power
-domain binding[2].
-
-Required properties:
-- compatible: Should be one of:
- "fsl,imx8qm-scu-pd",
- "fsl,imx8qxp-scu-pd"
- followed by "fsl,scu-pd"
-
-- #power-domain-cells: Must be 1. Contains the Resource ID used by
- SCU commands.
- See detailed Resource ID list from:
- include/dt-bindings/firmware/imx/rsrc.h
-
-Clock bindings based on SCU Message Protocol
-------------------------------------------------------------
-
-This binding uses the common clock binding[1].
-
-Required properties:
-- compatible: Should be one of:
- "fsl,imx8dxl-clk"
- "fsl,imx8qm-clk"
- "fsl,imx8qxp-clk"
- followed by "fsl,scu-clk"
-- #clock-cells: Should be 2.
- Contains the Resource and Clock ID value.
-- clocks: List of clock specifiers, must contain an entry for
- each required entry in clock-names
-- clock-names: Should include entries "xtal_32KHz", "xtal_24MHz"
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell.
-
-See the full list of clock IDs from:
-include/dt-bindings/clock/imx8qxp-clock.h
-
-Pinctrl bindings based on SCU Message Protocol
-------------------------------------------------------------
-
-This binding uses the i.MX common pinctrl binding[3].
-
-Required properties:
-- compatible: Should be one of:
- "fsl,imx8qm-iomuxc",
- "fsl,imx8qxp-iomuxc",
- "fsl,imx8dxl-iomuxc".
-
-Required properties for Pinctrl sub nodes:
-- fsl,pins: Each entry consists of 3 integers which represents
- the mux and config setting for one pin. The first 2
- integers <pin_id mux_mode> are specified using a
- PIN_FUNC_ID macro, which can be found in
- <dt-bindings/pinctrl/pads-imx8qm.h>,
- <dt-bindings/pinctrl/pads-imx8qxp.h>,
- <dt-bindings/pinctrl/pads-imx8dxl.h>.
- The last integer CONFIG is the pad setting value like
- pull-up on this pin.
-
- Please refer to i.MX8QXP Reference Manual for detailed
- CONFIG settings.

- "fsl,imx8qxp-sc-wdt"
- followed by "fsl,imx-sc-wdt";
