b0465fdfdd ARM: dts: BCM5301X: Specify flash partitions
Most devices use Broadcom standard partitions which allows them to be
described with the "brcm,bcm947xx-cfe-partitions". Exceptions are:
1) TP-LINK devices which use "os-image" partition with TRX containing
   kernel only + separated rootfs partition.
2) Asus RT-AC87U with custom "asus" partition.

This commit also removes undocumented and unsupported linux,part-probe
binding which got accidentally upstreamed while describing SPI
controller.

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)

9c281b5e12 ARM: dts: BCM5301X: Relicense Asus RT-AC87U file to the GPL 2.0+ / MIT
This matches licensing used by other BCM5301X files and is preferred as:
1) GPL 2.0+ makes is clearly compatible with Linux kernel
2) MIT is also permissive but preferred over ISC

This file were created and ever touched by a group of three people only:
Álvaro, Hauke and me.

0b660259e9 ARM: dts: BCM5301X: Don't use nonexistent "default-off" LED trigger
Such a trigger doesn't exist in Linux and is not needed as LED is being
turned off by default. This could cause errors in LEDs core code when
trying to set default trigger.

cd84661314 ARM: dts: BCM5301X: Relicense DTS files I created to the ISC
It's preferred to have DT source files licensed under BSD compatible
license. All new BCM5301X DTS files use ISC so let's also relicense old
ones to it.

Except for me only Hauke was ever touched these files in his commit
9faa5960ee ("ARM: BCM5301X: add NAND flash chip description") and
commit bb1d8fba19 ("ARM: BCM5301X: add NAND flash chip description for
Asus RT-AC87U").

a252ccd3d2 ARM: dts: BCM5301X: Specify all RAM by including an extra block
The first 128 MiB of RAM can be accessed using an alias at address 0x0.

In theory we could access whole RAM using 0x80000000 - 0xbfffffff range
(up to 1 GiB) but it doesn't seem to work on Northstar. For some reason
(hardware setup left by the bootloader maybe?) 0x80000000 - 0x87ffffff
range can't be used. I reproduced this problem on:
1) Buffalo WZR-600DHP2 (BCM47081)
2) Netgear R6250 (BCM4708)
3) D-Link DIR-885L (BCM47094)

So it seems we're forced to access first 128 MiB using alias at 0x0 and
the rest using real base address + 128 MiB offset which is 0x88000000.

fa87b008da ARM: BCM5301X: Enable UART on Netgear R8000
It was tested by LEDE users, all we need is to adjust clock frequency.
While we're at it create a separated DTS include file to share code with
other BCM4709 devices easier.

bb1d8fba19 ARM: BCM5301X: add NAND flash chip description for Asus RT-AC87U
The NAND flash chip description were not imported for the Asus RT-AC87U
dts file when this was done for all the other dts files, because these
patches were send in parallel.

This adds a missing NAND flash chip description to this patch:
