* ramips: mt7621-dts: add pinctrl properties for ethernetArınç ÜNAL2022-02-261-0/+3
| | | | | | | | | | | | | | | Add the missing pinctrl properties on the ethernet node. GMAC1 will start working with this change. Link: https://lore.kernel.org/netdev/83a35aa3-6cb8-2bc4-2ff4-64278bbcd8c8@arinc9.com/ Overwrite pinctrl-0 property without rgmii2_pins on devicetrees which use the rgmii2 pins as GPIO (22 - 33). Give gpio function to rgmii2 pin group on mt7621_tplink_archer-x6-v3.dtsi which uses GPIO 28. Signed-off-by: Arınç ÜNAL <arinc.unal@arinc9.com>

* kernel: backport MT7530 IRQ supportDENG Qingfang2022-02-101-0/+3
| | | | | | | | | | | Support MT7530 PHY link change interrupts, and enable for MT7621. For external MT7530, a GPIO IRQ line is required, which is board-specific, so it should be added to each DTS. In case the interrupt-controller property is missing, it will fall back to polling mode. Signed-off-by: DENG Qingfang <dqfext@gmail.com>

* ramips: mt7621-dts: remove ethsys nodeSergio Paracuellos2021-11-061-8/+1
| | | | | | | | | | | | | | | | 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.

* ramips: mt7621-dts: properly define 'cpc' and 'mc' nodesSergio Paracuellos2021-11-061-10/+10
| | | | | | | | | | | | | | | | 'cpc' and 'mc' nodes correspond with the MIPS 'Cluster Power Controller' and 'MIPS Common Device Memory Map' which are present in some MIPS related boards. 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. Also, move their definition to a proper place since both of them are not related with the palmbus at all.

* ramips: move aliases to the top in SoC DTSI filesAdrian Schmutzler2021-02-221-4/+4

* ramips: remove redundant status for USB controllersAdrian Schmutzler2020-12-071-1/+0
| | | | | | | | | | | | | | | | | | 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 Schmutzler2020-09-251-0/+2
| | | | | | | | | | | | | | | | | 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 Schmutzler2020-07-171-0/+4
| | | | | | | | | | | | | | | | | 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>

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 simplest way to do this is to use of_irq_parse_and_map_pci() and specify an interrupt-map which identifies the different PCI hosts by bus/slot numbers. This has the advantage that the hwirq number are mapped to virq numbers for us, so the ugly hack can go.
