The parameter value of below 3 properties are USB PHY specific. i.MX8MP
and i.MX95 USB PHY has different meanings. This will enlarge parameters
value and add constraints for them.
- fsl,phy-tx-vref-tune-percent
- fsl,phy-tx-rise-tune-percent
- fsl,phy-comp-dis-tune-percent

The ticket TKT0676370 shows the description of TX_VBOOST_LVL is wrong in
register PHY_CTRL3 bit[31:29].
011: Corresponds to a launch amplitude of 1.12 V.
010: Corresponds to a launch amplitude of 1.04 V.
000: Corresponds to a launch amplitude of 0.88 V.
After updated:
011: Corresponds to a launch amplitude of 0.844 V.
100: Corresponds to a launch amplitude of 1.008 V.
101: Corresponds to a launch amplitude of 1.156 V.
This will correct it accordingly.

The i.MX95 usb-phy can work with or without orientation-switch. With
current setting, if usb-phy works without orientation-switch, the
dt-schema check will show below error:
phy@4c1f0040: 'oneOf' conditional failed, one must be fixed:
'port' is a required property
'ports' is a required property
from schema $id: http://devicetree.org/schemas/phy/fsl,imx8mq-usb-phy.yaml#
This will correct the behavior of referring to usb-switch.yaml.

The usb phy in i.MX95 is compatible with i.MX8MP's, this will add a
compatible "fsl,imx95-usb-phy" for i.MX95. Also change reg maxItems
to 2 since i.MX95 needs another regmap to control Type-C Assist (TCA)
block. Since i.MX95 usb phy is able to switch SS lanes, this will also
add orientation-switch and port property to the file.

The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.
Drop trailing "bindings" in various forms (also with trailing full
stop):
find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
-not -name 'trivial-devices.yaml' \
-exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;
