Subject: [PATCH v4 0/2] Add support for QSGMII mode

Add compatible for J7200 CPSW5G.

Add support for QSGMII mode in phy-gmii-sel driver for CPSW5G in J7200.

Change log:

v3 -> v4:
1. Update $ref to /schemas/phy/phy-provider.yaml in
   Documentation/devicetree/bindings/mfd/ti,j721e-system-controller.yaml.
2. Update commit message for the "phy: ti: gmii-sel: Add support for
   CPSW5G GMII SEL in J7200" patch, describing the reason for defining the
   property "ti,qsgmii-main-ports" as an array.
3. Add a check in drivers/phy/ti/phy-gmii-sel.c to ensure that the value
   of the variable "main_ports" is within bounds. If the property
   "ti,qsgmii-main-ports" is either not mentioned in the devicetree or the
   value of the property is out of bounds, in both these cases,
   "main_ports" defaults to 1.
4. Use the function "of_property_read_u32()" instead of the function
   "of_property_read_u32_array()" in drivers/phy/ti/phy-gmii-sel.c.

v2 -> v3:
1. Add $ref to "phy@[0-9a-f]+$" pattern property in
   Documentation/devicetree/bindings/mfd/ti,j721e-system-controller.yaml.
2. Restrict the optional ti,qsgmii-main-ports property to
   ti,j7200-cpsw5g-phy-gmii-sel property by adding an else statement and
   disallowing it for other compatibles.
3. Move the "items" constraint for the ti,qsgmii-main-ports property to
   the place the property is defined.

v1 -> v2:
1. Rename ti,enet-ctrl-qsgmii as ti,qsgmii-main-ports.
2. Change ti,qsgmii-main-ports property from bitmask to integer.
3. Update commit message with property name as ti,qsgmii-main-ports.
