ARM: dts: BCM5301X: Relicense most DTS files to the GPL 2.0+ / MIT These files were created and ever touched by a group of three people only: Dan, Hauke and me. They were licensed under GNU/GPL or ISC. Introducing and discussing SPDX-License-Identifier resulted in a conclusion that ISC is a not recommended license (see also a license-rules.rst). Moveover an old e-mail from Alan Cox was pointed which explained that dual licensing is a safer solution than depending on a common compatibility belief. This commit switches most of BCM5301X DTS files to dual licensing using: 1) GPL 2.0+ to make sure they are compatible with Linux kernel 2) MIT to allow sharing with more permissive projects Both licenses belong to the preferred ones (see LICENSES/preferred/). An attempt to relicense remaining files will be made separately and will require approve from more/other developers.

ARM: dts: BCM5301X: Add basic DT for Linksys EA9200 It's tri-band wireless home router based on BCM4709A0 with 3 x BCM43602 chipsets. LEDs will be hopefully added later to the DT.

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 af850e14a7ae ("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.
