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)

This patch converts the WNDR3700 to use the interrupt-driven
gpio-keys driver over the polled variant.

>From the Documentation/devicetree/bindings/leds/common.txt:
- default-state : The initial state of the LED. Valid values are "on", "off",
and "keep". If the LED is already on or off and the default-state property is
set the to same value, then no glitch should be produced where the LED
momentarily turns off (or on). The "keep" setting will keep the LED at
whatever its current state is, without producing a glitch. The default is
off if this property is not present.
So setting the default-state of the LEDs to `off` is redundant as `off`
is default LED state anyway. We should remove it as almost every new
PR/patch submission contains this property by default which seems to be
just copy&paste from some DTS file already present in the tree.

Use the orange led by default to match the bootloader/stock firmware
behaviour. Turn on the green power led after boot to indicate a
finished boot and the orange one off.

Use diag.sh version used for apm821xx, ipq40xx and ipq806x, which
supports different leds for the different boot states.
The existing led sequences should be the same as before.

Add ath9k wifi capabilities to WNDR3700 family.
* use kmod-owl-loader to load firmware from "art"
* add wifi to DTS
* add wifi LEDs
Avoid using the same MAC for eth0 LAN and wlan0 by
toggling the eth0 MAC into a locally administered MAC.
That is currently done by in user-space by adding a
uci config item into /etc/config/network
(More elegant solution might be setting it already in
preinit phase.)
Known issues:
* wifi firmware file may not get created on the first boot
after flashing on time to bring wifi normally up. Likely
the overlay jffs2 is not yet ready for creating the
firmware file. "wifi up" may still bring wifi up.
Wifi will work normally at subsequent boots.
* phy0 and phy1 may get assigned mixed, so that phy0 may
be the 5GHz radio instead of the normal 2.4GHz, and vice
versa for phy1. Does not happen always, but may happen.

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.)
