Buttons of AVM FritzBox 4020 are incorrectly flagged as active high.
This was an oversight as RFKill button was working as expected even
with incorrectly flagged GPIO.

This commit adds support for the AVM Fritz!Box 4020 WiFi-router.
SoC: Qualcomm Atheros QCA9561 (Dragonfly) 750MHz
RAM: Winbond W971GG6KB-25
FLASH: Macronix MX25L12835F
WiFi: QCA9561 b/g/n 3x3 450Mbit/s
USB: 1x USB 2.0
IN: WPS button, WiFi button
OUT: Power LED green, Internet LED green, WLAN LED green,
LAN LED green, INFO LED green, INFO LED red
UART: Header Next to Black metal shield
Pinout is 3.3V - RX - TX - GND (Square Pad is 3.3V)
The Serial setting is 115200-8-N-1.
Tested and working:
- Ethernet (LAN + WAN)
- WiFi (correct MAC)
- Installation via EVA bootloader
- OpenWRT sysupgrade
- Buttons
- LEDs
Not working:
- USB port
Installation via EVA:
In the first seconds after Power is connected, the bootloader will
listen for FTP connections on 169.254.157.1 (Might also be 192.168.178.1). Firmware can be uploaded
like following:
ftp> quote USER adam2
ftp> quote PASS adam2
ftp> binary
ftp> debug
ftp> passive
ftp> quote MEDIA FLSH
ftp> put openwrt-sysupgrade.bin mtd1
Note that this procedure might take up to two minutes. After transfer is
complete you need to powercycle the device to boot OpenWRT.
