953efcb0c0 ARM: dts: BCM5301X: Add a default compatible for switch node
Provide a default compatible string which is based on the 53011 SRAB
compatible by default. The 4709 and 47094 default to the 53012 SRAB
compatible.

This allows us to have sane defaults and silences the following
warnings:

2f34ae32f5 ARM: dts: BCM5301X: Use corretc pinctrl compatible for 4709x
BCM47094 version of pinmux uses different compatible and supports MDIO
pinmux pins. Hence, use the correct compatible string and defines the
MDIO pins group.

d109673443 ARM: dts: BCM5301X: Relicense BCM47094 file to the GPL 2.0+ / MIT
This matches licensing used by other BCM5301X files and is preferred as:
1) GPL 2.0+ makes it clearly compatible with Linux kernel
2) MIT is also permissive but preferred over ISC

This file has been developed by me & once modified by Vivek.

37f6130ec3 ARM: dts: BCM5301X: Make USB 3.0 PHY use MDIO PHY driver
Currently, the USB 3.0 PHY in bcm5301x.dtsi uses platform driver which
requires register range "ccb-mii" <0x18003000 0x1000>. This range
overlaps with MDIO cmd and param registers (<0x18003000 0x8>).
Essentially, the platform driver partly acts like a MDIO bus driver,
hence to use of this register range.

In some Northstar devices like Linksys EA9500, secondary switch is
connected via external MDIO. The only way to access and configure the
external switch is via MDIO bus. When we enable the MDIO bus in it's
current state, the MDIO bus and any child buses fail to register because
of the register range overlap.

On Northstar, the USB 3.0 PHY is connected at address 0x10 on the
internal MDIO bus. This change moves the usb3_phy node and makes it a
child node of internal MDIO bus.

Thanks to Rafał Miłecki's commit af850e14a7 ("phy: bcm-ns-usb3: add
MDIO driver using proper bus layer") the same USB 3.0 platform driver
can now act as USB 3.0 PHY MDIO driver.

Tested on Linksys Panamera (EA9500)

7b790d3b29 ARM: dts: BCM5301X: Enable UART by default for BCM4708(1), BCM4709(4) & BCM53012
Every device tested so far got UART0 (at 0x18000300) working as serial
console. It's most likely part of reference design and all vendors use
it that way.

It seems to be easier to enable it by default and just disable it if we
ever see a device with different hardware design.

92b7b6ad1a ARM: BCM5301X: Specify USB 3.0 PHY in DT
Driver for Northstar USB 3.0 PHY has been recently added under the name
phy-bcm-ns-usb3. Add binding for it into the DT files.
The only slightly tricky part is BCM47094 which uses different PHY
version and requires different compatible value.
