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'
sed -i 's/ralink,function/function/g'
sed -i 's/ralink,nr-gpio/ralink,num-gpios/g'

0b68d081eb ramips: mt7628: update dts for upstream gpio-mt7621 driver
upstream driver merged 3 separated gpio banks into one gpio node.
and gpioX Y in our local driver should be replaced with gpio X*32+Y.

This patch is created using the following sed command:
sed -i -r 's/(.*)gpio([0-9]) ([0-9]+)(.*)/echo "\1gpio $((\2*32+\3))\4"/ge'

09d38a3bc3 ramips: remove bogus ralink,mtd-eeprom with offset 0x4
Several devices in mt76x8 subtarget use the following line to set
up wmac in their DTS(I) files:

ralink,mtd-eeprom = <&factory 0x4>

This is strange for several reasons:
- They should use mediatek,mtd-eeprom on this SOC
- The caldata is supposed to start at 0x0
- The parent DTSI mt7628an.dtsi specifies mediatek,mtd-eeprom anyway,
  starting from 0x0
- The offset coincides with the default location of the MAC address
  in caldata

Based on the comment in b28e94d4bf ("ramips: MiWiFi Nano fixes"),
it looks like the author for this device wanted to actually use
mtd-mac-address instead of ralink,mtd-eeprom. A check on the same
device revealed that actually the MAC address start at offset 4 there,
so the correct caldata offset is 0x0.

Based on these findings, and the fact that the expected location on
this SOC is 0x0, we remove the "ralink,mtd-eeprom = <&factory 0x4>"
statement from all devices in ramips (being only mt7628an anyway).

Thanks to Sungbo Eo for finding and researching this.

This patch does the following:

- prepend vendor name to model
- set status LEDs to follow the behavior in stock FW
- simplify state_default node definition
- use generic name for flash node

Stock FW status indicators:
https://files.xiaomi-mi.com/files/Mi_Router_Wi-Fi_Nano/Mi_router-NANO_EN.pdf
> Yellow: power on / off
> Blue: during normal operation
> Red: in case of problems with the operation of the device

556ff09875 ramips/mt762x: convert devices to interrupt-driven gpio-keys
This converts all remaining devices to use interrupt-driven
gpio-keys compatible instead of gpio-keys-polled.
The poll-interval is removed.

While at it, add/remove newlines in keys and leds node where
necessary.

7a21c85f70 ramips: improve support for Xiaomi Miwifi Nano
This patch does the following things:
1. mark u-boot-env writable
2. add bootcount support
   Currently, u-boot has a flag_boot_success env variable to reset.
   Also reset it in our firmware to follow the behavior in vendor's
   firmware.
3. disable usb support
   This router doesn't have usb port at all.
4. increase spi clock to 40MHz
5. fix pinmux groups
