This patch adds ar71xx's GPIO setup for the 2.4GHz and 5GHz antennae
demultiplexer:
| 158 /* 2.4 GHz uses the first fixed antenna group (1, 0, 1, 0) */
| 159 ap9x_pci_setup_wmac_gpio(0, (0xf << 6), (0xa << 6));
| 160
| 161 /* 5 GHz uses the second fixed antenna group (0, 1, 1, 0) */
| 162 ap9x_pci_setup_wmac_gpio(1, (0xf << 6), (0x6 << 6));
This should restore the range and throughput of the 2.4GHz radio
on all the derived wndr3700 variants and versions with the AR7161 SoC.
A special case is the 5GHz radio. The original wndr3700(v1) will
benefit from this change. However the wndr3700v2 and later revisions
were unaffected by the missing bits, as there is no demultiplexer
present in the later designs.
This patch uses gpio-hogs within the device-tree for all
wndr3700/wndr3800/wndrmac variants.
Notes:
Based on the PCB pictures, the WNDR3700(v1) really had eight
independent antennae. Four antennae for each radio and all of
those were printed on the circut board.
The WNDR3700v2 and later have just six antennae. Four of those
are printed on the circuit board and serve the 2.4GHz radio.
Whereas the remaining two are special 5GHz Rayspan Patch Antennae
which are directly connected to the 5GHz radio.
Hannu Nyman dug pretty deep and unearthed a treasure of information
regarding the history of how these values came to be in the OpenWrt
archives: <https://dev.archive.openwrt.org/ticket/6533.html>.
Mark Mentovai came across the fixed antenna group when he was looking
into the driver:
fixed_antenna_group 1, (0, 1, 0, 1)
fixed_antenna_group 2, (0, 1, 1, 0)
fixed_antenna_group 3, (1, 0, 0, 1)
fixed_antenna_group 4, (1, 0, 1, 0)

Add support for WNDR3700 and WNDR3700v2.
They share most things with WNDR3800.
Only device IDs and partition structure needs to be set.
Note: WNDR3700 (v1) has no NETGEAR_HW_ID, but has
also the NA version of the factory image.

Prepare for addition of WNDR3700 and WNDR3700v2 by
separating the common parts into wndr3700.dtsi and
leaving just the device-specific things into wndr3800.dts
The three routers are identical except
* device IDs
* WNDR3700 (v1) has only 8 MB flash, while others have 16 MB.
Partition structure needs to be defined for each device.
* (WNDR3800 has 128 MB RAM, but RAM size is not in DTS)
Also separate the common parts of the image recipe.
(Drop also the initramfs recipe.)

Bit 8/12 of reset controller which is marked as PHY_RESET/SWITCH_RESET
in datasheets will trigger either a reset for builtin switch or assert
an external ETH0_RESET_L/ETH1_RESET_L pin, which are usually connected
to external PHY/switch. None of them should be triggered every time an
interface is brought up in ethernet driver.
Remove PHY reset support from ag71xx and definition for them in dtsi.

Fixes for WNDR3800 DTS:
* fix bootcmd
* name art partition to reference it for MACs
* format firmware partition's address similarly as others
* make u-boot-env read-only like in ar71xx
* read wan and lan MACs from art
* fix LED and button gpio values to match ar71xx
(orange/green powerLED, reset button)
* enable power LED in dts by alias led-status
* define USB LED triggers and connect to USB port
* change wifi button to KEY_RFKILL like in ar71xx

This new syntax is slightly better designed & uses "compatible" string.

Some maintainers prefer DTS files licensed under permissive license like
MIT / BSD. As all DT bindings should be OS independent and DTS files are
pretty separated from Linux code it probably makes sense to share them
across projects.
The safest solution is to use dual licensing: that way it stays clear
these files can be used in GPL projects without depending on current
belief of licenses compatibility.

This target aims to replace ar71xx mid-term. The big part that is still
missing is making the MMIO/AHB wifi work using OF. NAND and mikrotik
subtargets will follow.
