Add the ranges property to the PCI bridges where missing. Add the unit
address to PCI bridge where missing.
Rework the complete rt3883 pci node. Drop the PCI unit nodes from the
dtsi. They are not used by any dts file and should be rather in the dts
than in the SoC dtsi. Express the PCI-PCI bridge in a clean devicetree
syntax. The ralink,pci-slot isn't used by any driver, drop it. Move the
pci interrupt controller out of the pci node. It doesn't share the same
reg and therefore should be an independent/SoC child node.
Move the pci related rt3883 pinctrl setting to the dtsi instead of
defining the very same for each rt3883 board.
If the device_type property is used for PCI units, the unit is treated
as pci bridge which it isn't. Drop it for PCI units.
Reference pci-bridges or the pci node defined in the dtsi instead of
recreating the whole node hierarchy. It allows to change the referenced
node in the dtsi without the need to touch all dts.
Fix the PCI(e) wireless unit addresses. All our PCI(e) wireless chips
are the first device on the bus. The unit address has to be the bus
address instead of the PCI vendor/device id.

I-O DATA WN-AX1167GR is a 2.4/5 GHz band 11ac router, based on
MediaTek MT7621A.
Specification:
- MT7621A (2-Cores, 4-Threads)
- 64 MB of RAM (DDR2)
- 16 MB of Flash (SPI)
- 2T2R 2.4/5 GHz
- 5x 10/100/1000 Mbps Ethernet
- 2x LEDs, 4x keys (2x buttons, 1x slide switch)
- UART header on PCB
- Vcc, GND, TX, RX from ethernet port side
- baudrate: 115200 bps (U-Boot, OpenWrt)
Stock firmware:
In the stock firmware, WN-AX1167GR has two os images each composed of
Linux kernel and rootfs.
These images are stored in "Kernel" and "app" partition of the
following partitions, respectively.
(excerpt from dmesg):
MX25L12805D(c2 2018c220) (16384 Kbytes)
mtd .name = raspi, .size = 0x01000000 (16M) .erasesize = 0x00010000 (64K) .numeraseregions = 0
Creating 10 MTD partitions on "raspi":
0x000000000000-0x000001000000 : "ALL"
0x000000000000-0x000000030000 : "Bootloader"
0x000000030000-0x000000040000 : "Config "
0x000000040000-0x000000050000 : "Factory"
0x000000050000-0x000000060000 : "iNIC_rf"
0x000000060000-0x0000007e0000 : "Kernel"
0x000000800000-0x000000f80000 : "app"
0x000000f90000-0x000000fa0000 : "Key"
0x000000fa0000-0x000000fb0000 : "backup"
0x000000fb0000-0x000001000000 : "storage"
The flag for boot partition is stored in "Key" partition, and U-Boot
reads this and determines the partition to boot.
If the image that U-Boot first reads according to the flag is
"Bad Magic Number", U-Boot then tries to boot from the other image.
If the second image is correct, change the flag to the number
corresponding to that image and boot from that image.
(example):
## Booting image at bc800000 ...
Bad Magic Number,FFFFFFFF
Boot from KERNEL 1 !!
## Booting image at bc060000 ...
Image Name: MIPS OpenWrt Linux-4.14.50
Image Type: MIPS Linux kernel Image (lzma compressed)
Data Size: 1865917 Bytes = 1.8 MB
Load Address: 80001000
Entry Point: 80001000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
raspi_erase_write: offs:f90000, count:34

Done!
Starting kernel ...
Flash instruction using factory image:
1. Connect the computer to the LAN port of WN-AX1167GR
2. Connect power cable to WN-AX1167GR and turn on it
3. Access to "192.168.0.1" on the web browser and open firmware
update page ("ファームウェア")
4. Select the OpenWrt factory image and perform firmware update
5. On the initramfs image, execute "mtd erase firmware" to erase stock
firmware and execute sysupgrade with sysupgrade image for WN-AX1167GR
6. Wait ~180 seconds to complete flasing
