Serge Vasilugin reports:
To improve mt7620 built-in wifi performance some changes:
1. Correct BW20/BW40 switching (see comments with mark (1))
2. Correct TX_SW_CFG1 MAC reg from v3 of vendor driver see
https://gitlab.com/dm38/padavan-ng/-/blob/master/trunk/proprietary/rt_wifi/rtpci/3.0.X.X/mt76x2/chips/rt6352.c#L531
3. Set bbp66 for all chains.
4. US_CYC_CNT init based on Programming guide, default value was 33 (pci),
set chipset bus clock with fallback to cpu clock/3.
5. Don't overwrite default values for mt7620.
6. Correct some typos.
7. Add support for external LNA:
a) RF and BBP regs never be corrected for this mode
b) eLNA is driven the same way as ePA with mt7620's pin PA
but vendor driver explicitly pin PA to gpio mode (for forrect calibration?)
so I'm not sure that request for pa_pin in dts-file will be enough
First 5 changes (really 2) improve performance for boards w/o eLNA/ePA.
Changes 7 add support for eLNA
Configuration w/o eLAN/ePA and with eLNA show results
tx/rx (from router point of view) for each stream:
35-40/30-35 Mbps for HT20
65-70/60-65 Mbps for HT40
Yes. Max results for 2T2R client is 140-145/135-140
with peaks 160/150, It correspond to mediatek driver results.
Boards with ePA untested.

DTS properties that match *-gpios are treated specially.
Use ngpios instead, as most GPIO drivers upstream do.
Fixes 5.10 DTS errors such as:
OF: /palmbus@300000/gpio@600: could not find phandle
Fixes DTC warnings such as:
Warning (gpios_property): /palmbus@300000/gpio@600:ralink,num-gpios:
Could not get phandle node for (cell 0)

The aliases node is expected as one of the first entries, and
having it there matches alphabetic sorting as well.

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.

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.

The latest dtc compiler considers nodes named i2c or spi as the
respective bus:
/pinctrl/i2c: incorrect #address-cells for I2C bus
/pinctrl/spi: incorrect #address-cells for SPI bus
Rename the node to fix the false positives.
Fix the spi node unit address for the DWR-512-B and UBNT-ER-e50 to get
rid of the following warning:
SPI bus unit address format error, expected "n"

Assign the usbdev trigger via devicetree for all subtargets and drop
the userspace handling of the usb leds.
With the change all usb ports are triggering the usb led instead of
only usb 1.1 XOR usb 2.0 XOR usb 3.0 as it was before.

Set the pins to the required mode via the pinmux driver. It allows to

The mt7620 doesn't have a pinmux group named spi_cs1. The cs1 is part
of the "spi refclk" group. The function "spi refclk" enables the second
chip select.
On reset, the pins of the "spi refclk" group are used as reference
clock and GPIO.

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.

Since commit c1e7738988f5 ("checks: add gpio binding properties check")
dtc treats any *-gpios and *-gpio property as phandle at least during
checks. The only whitelisted property is nr-gpio.
Use ralink,nr-gpio in favour of ralink,num-gpios to get rid of false
positive warnings.

The cpu interrupt controller doesn't have a reg property, hence we
can't use a unit address in the node name.

The Ralink USB PHY driver merged into mainline has a slightly different
device tree binding than the patch that was used with linux 4.9.
The new driver requires a `ralink,sysctl` node pointing to the `syscon`
node.
This patch also sets `#phy-cells` to 0, as recommended by the mainline
documentation [1].

This commit makes the following modifications to ramips dts files:
1. Add clkctrl node to all dtsi files (although not used for now)
2. Add clocks and clock-names properties to some nodes (usbphy, pci)
3. Add usbphy node for rt3050 (although not used for now)
4. Add clock-frequency to uart nodes in mt7621.dtsi and mt7628an.dtsi
These modifications, although not fully used at the moment, will make
it easier for FreeBSD to adopt and use LEDE ramips dts files with
minimal changes for easier maintenance.

The following patch fixes:
* wrong indentations
* doubled gpio-keys-polled nodes (DIR-300-B7, DIR-320-B1, DIR-610-A1)
* duplicate spacings
* empty lines at end of files and after last child nodes
* trailing and leading whitespace
* unnecessary and commented-out code
* missing empty lines between nodes and between properties and nodes
* unnecessary empty lines between nodes properties [1]
in .dts{,i} files, for ramips target.
[1] Some of empty lines in SOCs dtsi files were left untouched, because they seem to be there for a reason (readability?).
