0e4f49a90d ramips: remove useless resets properties from SoC dtsi
These drivers don't request reset control. And most reset properties
even have incorrect reset source definitions.

1. interrupt controller, ref: arch/mips/ralink/irq.c
2. memory controller, ref: arch/mips/ralink/of.c
3. gpio controller, ref: drivers/gpio/gpio-ralink.c (local patch)
4. systic, ref: arch/mips/ralink/cevt-rt3352.c
5. pwm, ref: drivers/pwm/pwm-mediatek-ramips.c (local patch)

Tested on MT7620 && MT7628.

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)

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.

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.

rid of the following warning:

f9b8328d79 ramips: fix pci/pcie related dtc warnings
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.

positive warnings.

eda27d7557 ramips: fix usbphy DT nodes on linux 4.14
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].

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.

 * missing empty lines between nodes and between properties and nodes
 * unnecessary empty lines between nodes properties [1]
