b17cc131c6 ramips: remove systick node for mt7621 SoC dtsi
This node is useless because MT7621 uses the generic mips systick
driver instead of the ralink systick driver.

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.

96010bb17c ramips: mt7621-wdt: use phandle to access system controller registers
These patches allow the driver to access some watchdog registers via a
phandle to the system controller node[1]. To apply these changes, we
need to add "mediatek,sysctl" to the SoC dtsi. This commit also remove
the redundent clocks, interrupts and resets properties.

8cacf2bda8 ramips: add proper system clock and reset driver support for mt7621
This series of upstream patches makes the system controller node as a
reset provider[1][2], and it also includes some clock and reset driver
fixes[3][4]. Meanwhile, all clocks and resets properties in the SoC
device tree have been updated to be compatible with the new driver.

DT 'ethsys' node is being configured as a syscon
to get access to reset and other registers in the
'mediateķ,mt7621-eth' driver. Since the 'sysc' is also
a syscon, provides the clock and also is virtually
mapped from the same physical address 0x1e000000 we
can just use 'sysc' as the phandle for the syscon in
the ethernet node. Compatible string 'mediatek,mt7621-ethsys'
of the node is not being used anywhere inside the kernel
so, this node can be safely removed.

- Documentation/devicetree/bindings/bus/mti,mips-cdmm.yaml

Hence, properly update compatible strings and align nodes with already
mainlined bindings documentation. Also, move their definition to a proper
place since both of them are not related with the palmbus at all.

66d12ce667 ramips: remove redundant status for USB controllers
mt7621, mt7628an and rt5350 have USB controllers (ehci/ohci or xhci)
enabled by default. Thus, this patch drops redundant status=okay
statements in derived device DTS files.

While at it, also drop an explicit status=okay in mt7621.dtsi, as
this is default.

Note:

For rt5350, about 50 % of the devices enabled ehci/ohci in the DTS
files, and there is actually no device actively disabling it.
It looks like only a few people are aware that the controllers are
enabled by default here.

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.

device DTS/DTSI files. However, 44 of 74 statements use the
following setting:

	chosen {

	};

Therefore, don't repeat ourselves and move that definition to the SoC
DTSI file to serve as a default value.

This patch is cosmetic.

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
