1f818b09f8 ramips: add proper system clock and reset driver support for legacy SoCs
This series of upstream patches properly implement a clock and reset
driver for old ralink SoCs[1]. And it includes some related fixes[2] and
improvements[3][4]. All patches have been merged into linux-next. They
will be part of upcoming Linux 6.5. In order to switch to the new system
controller driver, all clocks and resets properties in SoC dtsi have been
updated, and kernel symbol "CONFIG_CLK_MTMIPS" have been added to the
kernel config files.

85ca6923bc ramips: gpio-ralink: use ngpios, not ralink,num-gpios
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)

d4520d75a1 ramips: move aliases to the top in SoC DTSI files
The aliases node is expected as one of the first entries, and
having it there matches alphabetic sorting as well.

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.

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.

ffa55386f1 ramips: fix dtc compiler warnings
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"

d8e7a526a3 ramips: use ralink,nr-gpio instead of ralink,num-gpios
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.

ffaaa6788a ramips: DTS modifications
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.

553fea9f19 ramips: fix indentation and other mistakes in .dts{, i} files
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?).
