47db830b82 ramips: mt7620: move mt7620_mdio_mode() to ethernet driver
The function mt7620_mdio_mode is only called once
and both the function and mdio_mode block have been named incorrectly,
leading to confusion and useless commits.

These lines in the mdio_mode block of mt7620_hw_init
are only intended for boards with an external mt7530 switch.
(see commit 194ca6127e)

Therefore, move lines from mdio_mode to the place in soc_mt7620.c
where the type of mt7530 switch is identified,
and move lines from mt7620_mdio_mode to a main function.

mt7620_mdio_mode was called from mt7620_gsw_init
where the priv struct is available,
so the lines must stay in mt7620_gsw_init function.

In order to keep things as simple as possible,
keep the DTS property related function calls together,
by moving them from mt7620_gsw_probe to init.

Remove the now useless DTS properties and extra phy nodes.

6876465875 ramips: mt7620: use DTS to set PHY base address for external PHYs
Set the PHY base address to 12 for mt7530 and 8 for others,
which is based on the default setting for some devices
from printing the register with the following command
after it is written to by uboot during the boot cycle.

`md 0x10117014 1`

PHY_BASE option only uses 5 bits of the register,
bits 16 to 20, so use 8-bit integer type.

Set the option using the DTS property mediatek,ephy-base
and create the gsw node if missing.

Also, added a kernel message to display the EPHY base address.

Note:
If anything is written to a PHY address that is greater than 1 hex char (greater than 0xf)
then there is adverse effects with Atheros switches.

a14c2d409c ramips: mt7620: simplify DTS properties for GMAC
There are only 2 options in the driver
for the function of mt7620 internal switch port 4:

  EPHY mode (RJ-45, internal PHY)
  GMAC mode (RGMII, external PHY)

Let the DTS property be boolean instead of string
where EPHY mode is the default.

Fix how the properties are written
for all DTS that use them,
and add missing nodes where applicable,
and remove useless nodes,
and minor DTS formatting.

c846dd91f0 ramips: remove model name from LED labels
Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.

The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.

For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things
easier.

621297e867 ramips: move dts-v1 statement to top-level DTSI files
The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.

In ramips, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent mtxxxx/rtxxxx DTSI files already determines the DTS
version, so putting it into the DTS files is just a useless repetition.

Consequently, this patch puts the dts-v1 statement into the top-level
SoC-based DTSI files, and removes all other occurences.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes accordingly where necessary.

d7a28e8ed2 ramips: mt7620: tidy up ethernet node in DTS files
This tidies up the ethernet node in mt7620 DTS files by:

- removing unnecessary status as it is not disabled
- reordering properties consistently
- adding empty lines to enhance readability

This should make comparison and reviewing new PRs based on C/P easier.

b756ea2a90 ramips: replace pinctrl property names
Upstream pinctrl driver in drivers/staging uses
groups/function/ralink,num-gpios instead of
ralink,group/ralink,function/ralink,nr-gpio
Replace these properties in dts as well as the pinctrl driver in
patches-4.14.
This commit is created using:
sed -i 's/ralink,group/groups/g'

e4ce3109f2 ramips: simplify state_default/pinctrl0 in device DTS files
The node pinctrl0 is already set up in the SOC DTSI files, but
defined again as member of pinctrl in most of the device DTS(I)
files. This patch removes this redundancy for the entire ramips
target.

3df3bb0dae ramips: add support for EnGenius ESR600
The EnGenius ESR600 is a dual band wireless router with a 4-port gigabit
Ethernet switch, a gigabit Ethernet WAN port and a USB port.

Specification:

- Bootloader:	U-Boot
- SoC:		MediaTek MT7620A (600 MHz)
- Flash:	16MB, Macronix MX25L12845E
- RAM:		64MB, Nanya NT5TU32M16DG-AC
- Serial:	115200 baud, no header, 3.3V
  		J2: Vcc (arrow), Gnd, Tx, Rx
- USB:		USB 2, 5V
- Ethernet:	5 x 1 Gb/s 4 LAN 1 WAN, Atheros AR8327
- WiFi0:	5 GHz 802.11 b/g/n Ralink RT5592N
  		300 Mb/s, 2T2R
- WiFi1:	2.4 GHz 802.11 b/g/n integrated
  		300 Mb/s, 2T2R
- Antennas:	2 per radio, internal
- LEDs:		1 programmable power (amber)
  		2 programable radio (blue)
		1 programable WPS-5G (blue)
		1 non-programable WAN activity (blue)
		1 unconfigured WPS-2.4G (amber)
- Buttons:	GPIO: Reset, WPS

Installation:

Use the OEM web interface to install the ...-factory.dlf image.
Use the OpenWRT ...-sysupgrade.bin image for future upgrades.

The J2 serial port can be accessed either by soldering in a header,
standard 0.1" spacing, or by using pogo-pins against the back side.

As configured by the OEM, the U-Boot boot delay is short, however quickly
typing "1" leads to the U-Boot "System load Linux to SDRAM via TFTP"
prompt.  The TFTP client is configured by default with
     client:   192.168.99.9
     server:   192.168.99.8
     filename: uImageESR600
It will load an OpenWRT initramfs kernel with this method.

Known issues:

1) Only the ports externally labeled WAN, LAN3 and LAN4 are operational.
LAN1 and LAN2 do not appear to power up. This issue is also present
in the Lava LR25G001.

2) The amber WPS-2.4G LED, in the same lightguide as the blue WPS-5G LED,
is not configured in the Device Tree specification.

3) The blue WAN activity LED is not configured in the Device Tree
specification as this causes the AR8327 switch to fail to initialize.
