Convert TI CPPI 4.1 DMA controller text bindings to DT schema. Add
ti,am3359-cppi41 and ti,da830-cppi41 into single schema since they share
the same hardware IP block and driver. Add undocumented #dma-requests
and power-domains properties to match existing DTS usage.

Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [Medium] The `interrupts` property is not marked as required for the `ti,da830-cppi41` hardware variant, allowing incomplete nodes to pass schema validation.
- [Low] Missing property type definitions for deprecated custom properties `#dma-channels` and `#dma-requests`.
- [Low] The unit address in the example node name does not match the first `reg` address.

dt-bindings: dma: ti,cppi41: Convert to DT schema
This commit converts the TI CPPI 4.1 DMA controller text bindings to DT
schema. It merges ti,am3359-cppi41 and ti,da830-cppi41 into a single schema
and adds undocumented properties like power-domains to match existing device
tree usage.

[Severity: Low]
Are the #dma-channels and #dma-requests custom properties missing a type
definition?
The schema tool strictly requires all properties that do not match core
regex patterns to have an explicit type via a reference. Without a type
definition, does this regression cause schema validation to fail when
checking the bindings?

[Severity: Medium]
Should the interrupts property be marked as required in this else block for
the ti,da830-cppi41 hardware variant?
If incomplete nodes pass schema validation without an interrupts property,
won't this regression cause the driver probe to fail when it attempts to parse
and map the interrupt?

[Severity: Low]
Is the unit address in the dma-controller@7402000 node name mismatched with
the first reg address?
The node name uses 7402000, but the first register address is 0x47400000.
Will this formatting regression cause a compiler warning when the examples are
evaluated?

Convert the TI AM33xx MUSB text bindings to DT schema.
Changes during conversion:
- Allow an optional vbus interrupt used in am335x-bone-common.
- Add the interface-type and phy-names properties natively used by the
dm816x hardware.
- Allow 0 or 1 for mentor,multipoint. While the text binding mandated 1,
the Mentor USB IP natively supports both single and multipoint
configurations as used in existing DTS.

dt-bindings: usb: ti,musb-am33xx: Convert to DT schema
This commit converts the TI AM33xx MUSB text bindings to DT schema. It also
allows an optional vbus interrupt and adds interface-type and phy-names
properties for dm816x hardware.

[Severity: Low]
Is mentor,ram-bits missing a type definition?
Without a type reference for a custom property, make dt_binding_check issues
a 'missing type definition' warning and fails constraint evaluation against
valid DTS usage. DT schema parses cell arrays like <12> as matrices like
[[12]] if not told they are scalar integers, failing the const: 12 check.
Does this need a type reference like
$ref: /schemas/types.yaml#/definitions/uint32 similar to mentor,num-eps and
mentor,power?

[Severity: Low]
Does this YAML conversion lose some of the documentation details from the
original text binding?
The previous text binding included explicit descriptions for the two reg
entries ("USB control registers" and "USB wake up control"). While reg-names
are provided below, should an items list under reg be included to preserve
these explicit descriptions?

Convert the TI AM33xx USB Wrapper text binding to DT schema.
Changes during conversion:
- Drop the USB control module from child nodes, as it physically resides
within the System Control Module address space, not the USB wrapper.
- Allow standard phy@[0-9a-f]+$ child node names alongside the legacy
usb-phy@[0-9a-f]+$.
- Mark the legacy ti,hwmods property as deprecated.
- Document required #address-cells, #size-cells, and ranges property
missing from text binding.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] Undefined labels in the YAML example cause `dtc` compilation to fail during `make dt_binding_check`.

dt-bindings: usb: ti,am33xx-usb: Convert to DT schema
This commit converts the TI AM33xx USB Wrapper text binding to DT schema.
It drops the USB control module from child nodes, allows standard phy child
node names, and marks the legacy ti,hwmods property as deprecated.

[Severity: Low]
Does this reference to ctrl_mod cause a build failure during dtc compilation?
The control module node and its label appear to have been removed from the
example during the text-to-YAML conversion, which may result in a fatal
"Reference to non-existent node or label" error when running make
dt_binding_check.

[Severity: Low]
Will dtc compilation fail on this phandle reference? The usb0_phy label
was removed from the usb-phy@47401300 node in the example above, meaning
this reference is undefined and may break make dt_binding_check.

Convert the TI DA8xx/OMAP-L1x MUSB text bindings to DT schema. Since
DA8xx MUSB node acts as a parent bus for the CPPI41 DMA controller add
required #address-cells, #size-cells, and ranges properties.

-TI DA8xx MUSB
-~~~~~~~~~~~~~
-For DA8xx/OMAP-L1x/AM17xx/AM18xx platforms.
-
-Required properties:
-~~~~~~~~~~~~~~~~~~~~
- - compatible : Should be set to "ti,da830-musb".
-
- - reg: Offset and length of the USB controller register set.
-
- - interrupts: The USB interrupt number.
-
- - interrupt-names: Should be set to "mc".
-
- - dr_mode: The USB operation mode. Should be one of "host", "peripheral" or "otg".
-
- - phys: Phandle for the PHY device
-
- - phy-names: Should be "usb-phy"
-
- - dmas: specifies the dma channels
-
- - dma-names: specifies the names of the channels. Use "rxN" for receive
- and "txN" for transmit endpoints. N specifies the endpoint number.
-
-Optional properties:
-~~~~~~~~~~~~~~~~~~~~
- - vbus-supply: Phandle to a regulator providing the USB bus power.
