0d4616b838 ramips: dts: add the missing interrupt properties for GPIO nodes
The Ralink GPIO driver supports irqchip function. Hence we need to
add "interrupt-parent" and "interrupt-controller" properties to make
sure it works properly. It is worth noting that all GPIO devices
share the same interrupt line.

338f40b3b4 ramips: make SoC dtsi compatible with upstream mmc-mtk driver
Add all essential MTK SDHC properties to support the new mmc-mtk
driver. Since this driver relies on power regulators, we also
need to enable this feature for MT7620, just like MT762{1,8}.

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:

f547fc9d57 ramips: reset mt7620 ethernet phy via reset controller
Use reset controller to reset mt7620 ethernet phy instead of directly
writing system control registers. The reset line of "ephy" is 24, so
the DTS resets properties have been updated to get the correct reset
signal.

Tested on HiWiFi HC5861.

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.

31a6605de0 mac80211: rt2x00: experimental improvements for MT7620 wifi
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.

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.

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.

The Ralink USB PHY driver merged into mainline has a slightly different

The new driver requires a `ralink,sysctl` node pointing to the `syscon`

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.
