24459dc108 ramips: gpio: always use dynamic GPIO numberspace base
The new numberspace base starts from 512 instead of 0. The number
base seems come from the kernel symbol CONFIG_GPIOLIB_FASTPATH_LIMIT.

Suppress warning:

gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.

fc92fecfc7 ramips: dts: rt5350: reset FE and ESW cores together
Failing to do so will cause the DMA engine to not initialize properly
and fail to forward packets between them, and in some cases will cause
spurious transmission with size exceeding allowed packet size, causing a
kernel panic.

This is behaviour of downstream driver as well, however I
haven't observed bug reports about this SoC in the wild, so this
commit's purpose is to align this chip with all other SoC's - MT7620
were already using this arrangement.

even have incorrect reset source definitions.

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.

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.

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].

c7efbd7dbb ramips: Add specific compatible properties for esw
Currently, for RT5350 and MT7628, esw is marked as compatible with
"ralink,rt3050-esw". While this is true, the switches within RT5350
and MT7628 actually support more functionality than the RT3050 switch.

One such example is per-VLAN untagging, which is an important feature.

RT3352 is another example of this, but it already has an additional
compatible property, which allows to differentiate it from RT3050.

This commit adds such more specific properties for RT5350 and MT7628
as well.

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.

6801c4e33e ramips: HLK-RM04 - Enable GPIO14 for WPS button
The top half of UARTF on the HLK-RM04 is used for GPIO.

  mode 1   mode 2
   RIN     GPIO14
   DSR_N   GPIO13
   DCD_N   GPIO12
   DTR_N   GPIO11
   RXD     GPIO10
   CTS_N   GPIO09
   TXD     GPIO08
   RTS_N   GPIO07

This patch applies 3'b101 mode to UARTF:

   GPIO14
   GPIO13
   GPIO12
   GPIO11
   RXD
   CTS_N
   TXD
   RTS_N

Because the base rt5350.dtsi file forces 3'b000 mode, remove the pin setting from this file and apply it directly to the files that inherit from it (WIZFI630A.dts and WT1520.dtsi).  This change makes the rt5350.dtsi file consistent with the mt7620a.dtsi file.

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

[1] Some of empty lines in SOCs dtsi files were left untouched, because they seem to be there for a reason (readability?).

I tested it on a VoCore. Works fine connected to a second flash, but fails to detect MMC/SD cards due to SPI clock speed.
