3690c4a092 ramips: improve support for Zyxel Keenetic Extra II
- drop unneeded default-state for led_power
- concat firmware partitions to extend available free space
- increase spi flash frequency to 32 Mhz (value from stock firmware bootlog)
- drop broken-flash-reset because of onboard flash chip W25Q256FV has reset support
- add compatible for pcie wifi according to kernel documetation
- switch to wan mac address with offset 0x28 in rf-eeprom

74516f4357 ramips: fix reboot for remaining 32 MB boards
The following devices have a Winbond W25Q256FV flash chip,
which does not have the RESET pin enabled by default,
and otherwise would require setting a bit in a status register.

Before moving to Linux 5.4, we had the patch:
0053-mtd-spi-nor-add-w25q256-3b-mode-switch.patch
which kept specific flash chips with explicit 3-byte and 4-byte address modes
to stay in 3-byte address mode while idle (after an erase or write)
by using a custom flag SPI_NOR_4B_READ_OP that was part of the patch.

this was obsoleted by the patch:
481-mtd-spi-nor-rework-broken-flash-reset-support.patch
which uses the newer upstream flag SNOR_F_BROKEN_RESET
for devices with a flash chip that cannot be hardware reset with RESET pin
and therefore must be left in 3-byte address mode when idle.

The new patch requires that the DTS of affected devices
have the property "broken-flash-reset", which was not yet added for most of them.

This commit adds the property for remaining affected devices in ramips target,
specifically because of the flash chip model.

However, it is possible that there are other devices
where the flash chip uses an explicit 4-byte address mode
and the RESET pin is not connected to the SOC on the board,
and those DTS would also need this property.

ad6b077049 ramips: mt7628: move mtd-eeprom out of root DTSI
The mt76x8 subtarget is the only one in ramips that stores the
mediatek,mtd-eeprom property directly in the "root" mt7628an.dtsi.

This is not optimal for a few different reasons:

 * If you don't really know it or are used to other (sub)targets,
   the property will be set somewhat magically.
 * The property is set based on &factory partition before (if at all)
   this partition is defined.
 * There are several devices that have different offset or even
   different partitions to read from, which will then be overwritten
   in the DTS files. Thus, definitions are scattered between root
   DTSI and individual files.

Based on these circumstances, the "root" definition is removed and
the property is added to the device-based DTS(I) files where needed
and applicable. This should be easier to grasp for unexperienced
developers and will move the property closer to the partition
definitions.

66d12ce667 ramips: remove redundant status for USB controllers
mt7621, mt7628an and rt5350 have USB controllers (ehci/ohci or xhci)
enabled by default. Thus, this patch drops redundant status=okay
statements in derived device DTS files.

While at it, also drop an explicit status=okay in mt7621.dtsi, as
this is default.

Note:

For rt5350, about 50 % of the devices enabled ehci/ohci in the DTS
files, and there is actually no device actively disabling it.
It looks like only a few people are aware that the controllers are
enabled by default here.

c846dd91f0 ramips: remove model name from LED labels
Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.

The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.

For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things
easier.

621297e867 ramips: move dts-v1 statement to top-level DTSI files
The "/dts-v1/;" identifier is supposed to be present once at the
top of a device tree file after the includes have been processed.

In ramips, we therefore requested to have in the DTS files so far,
and omit it in the DTSI files. However, essentially the syntax of
the parent mtxxxx/rtxxxx DTSI files already determines the DTS
version, so putting it into the DTS files is just a useless repetition.

Consequently, this patch puts the dts-v1 statement into the top-level
SoC-based DTSI files, and removes all other occurences.
Since the dts-v1 statement needs to be before any other definitions,
this also moves the includes accordingly where necessary.

1eceab3fc0 ramips: dts: use generic node name for flash
In DTS Checklist[1] we're now demanding proper generic node names, as
the name of a node should reflect the function of the device and use
generic name for that[2]. Everybody seems to be copy&pasting from DTS
files available in the repository today, so let's unify that naming
there as well and provide proper examples.

While at it, remove unused m25p80 label.

Tested on rt5350 (for spi-nor) and rt3662 (for cfi-flash).

7a387bf9a0 ramips: mt76x8: fix bogus mediatek,portmap
mt76x8 uses esw_rt3050 driver, which does not accept mediatek,portmap with
string values. Convert the strings to integers to make it work.

According to its switch setup, WRTnode 2P/2R have a WAN port at port 0,
so the correct value should be 0x3e.

tplink_8m.dtsi uses "llllw", but it does not match switch setups of any
device using the DTSI. Remove it from the DTSI and add correct value to DTS
for each device.

These devices have a WAN port at port 0. Set the value to 0x3e.
- tplink,archer-c20-v4
- tplink,archer-c50-v3
- tplink,tl-mr3420-v5
- tplink,tl-wr840n-v4
- tplink,tl-wr841n-v13
- tplink,tl-wr842n-v5

These devices have only one ethernet port. They don't need portmap setting.

fef1810897 ramips: mt76x8: use flash location for wan_mac in 02_network
This uses the flash locations instead of eth0 MAC address to
calculate MAC address increments for WAN.

The change will make the MAC address setup of a particular device
more obvious and removes the dependency of 02_network on the eth0
initialization.
