* ramips: mt7621-dts: describe switch PHYs and adjust PHY muxingArınç ÜNAL2024-05-01
| | | | | | | | | | | | | | | | | | | | | | | | Currently, the MT7530 DSA subdriver configures the MT7530 switch to provide direct access to switch PHYs, meaning, the switch PHYs listen on the MDIO bus the switch listens on. The PHY muxing feature makes use of this. This is problematic as the PHY may be attached before the switch is initialised, in which case, the PHY will fail to be attached. Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration of switch MDIO bus") on mainline Linux, we can describe the switch PHYs on the MDIO bus of the switch on the device tree. When the PHY is described this way, the switch will be initialised first, then the switch MDIO bus will be registered. Only after these steps, the PHY will be attached. Describe the switch PHYs on mt7621.dtsi and remove defining the switch PHY on the SoC's mdio bus node. When the PHY muxing is in use, the interrupts for the muxed PHY won't work, therefore delete the "interrupts" property on the devices where the PHY muxing feature is in use.

* ramips: mt7621-wdt: use phandle to access system controller registersShiji Yang2023-07-30
| | | | | | | | | | | | | 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.

* ramips: mt7621-dts: remove ethsys nodeSergio Paracuellos2021-11-06
| | | | | | | | | | | | | | | | 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.

There is already bindings documentation for these two located in: - Documentation/devicetree/bindings/power/mti,mips-cpc.yaml - Documentation/devicetree/bindings/bus/mti,mips-cdmm.yaml Hence, properly update compatible strings and align nodes with already mainlined bindings documentation.

* ramips: remove redundant status for USB controllersAdrian Schmutzler2020-12-07
| | | | | | | | | | | | | | | | | | 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. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: move dts-v1 statement to top-level DTSI filesAdrian Schmutzler2020-09-25
| | | | | | | | | | | | | | | | | 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. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: move redundant console setup to mt7621 SoC DTSIAdrian Schmutzler2020-07-17
| | | | | | | | | | | | | | | | | For mt7621, console is set up via DTS bootargs individually in device DTS/DTSI files. However, 44 of 74 statements use the following setting: chosen { bootargs = "console=ttyS0,57600"; }; Therefore, don't repeat ourselves and move that definition to the SoC DTSI file to serve as a default value. This patch is cosmetic. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

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.
