mips: dts: ralink: add MT7621 SoC

2022-03-16T14:10:23Z

The MT7621 system-on-a-chip includes an 880 MHz MIPS1004Kc dual-core CPU, a 5-port 10/100/1000 switch/PHY and one RGMII. Add the devicetrees for GB-PC1 and GB-PC2 devices which use MT7621 SoC.

staging: mt7621-dts: fix cpuintc and fixedregulator dtc warnings, fix xhci

2022-03-14T15:01:31Z

Fix the cpuintc and fixedregulator dtc warnings: Warning (unit_address_vs_reg): /cpuintc@0: node has a unit name, but no reg property Warning (unit_address_vs_reg): /fixedregulator@0: node has a unit name, but no reg property Warning (unit_address_vs_reg): /fixedregulator@1: node has a unit name, but no reg property Warning (unique_unit_address): /cpuintc@0: duplicate unit-address (also used in node /fixedregulator@0) Remove the unnecessary status = "okay" property from the xhci node.

staging: mt7621-dts: fix GB-PC2 devicetree

2022-03-14T15:01:27Z

Fix the GB-PC2 devicetree. Refer to the schematics of the device for more information. GB-PC2 devicetree fixes: - Include mt7621.dtsi instead of gbpc1.dts. Add the missing definitions. - Remove gpio-leds node as the system LED is not wired to anywhere on the board and the power LED is directly wired to GND. - Remove uart3 pin group from gpio-pinmux node as it's not used as GPIO. - Use reg 7 for the external phy to be on par with Documentation/devicetree/bindings/net/dsa/mt7530.txt. - Use the status value "okay".

staging: mt7621-dts: fix LEDs and pinctrl on GB-PC1 devicetree

2022-03-14T15:01:27Z

Fix LED and pinctrl definitions on the GB-PC1 devicetree. Refer to the schematics of the device for more information. LED fixes: - Change GPIO6 LED label from system to power as GPIO6 is connected to PLED. - Add default-on default-trigger to power LED. - Change GPIO8 LED label from status to system as GPIO8 is connected to SYS_LED. - Add disk-activity default-trigger to system LED. - Switch to the color:function naming scheme. - Remove lan1 and lan2 LEDs as they don't exist. Pinctrl fixes: - Claim state_default node under pinctrl node. - Change pinctrl0 node name to state-default. - Change gpio node name to gpio-pinmux to respect Documentation/devicetree/bindings/pinctrl/ralink,rt2880-pinmux.yaml. - Sort pin groups alphabetically. Misc fixes: - Fix formatting. - Use the status value "okay". - Define hexadecimal addresses in lower case. - Make hexadecimal addresses for memory easier to read.

staging: mt7621-dts: do not use rgmii2_pins for ethernet on GB-PC1

2022-02-15T16:11:45Z

GB-PC1 uses some of the rgmii2 pins (22 - 33) as GPIO. Therefore, the rgmii2 bus cannot be used on this device. Overwrite pinctrl-0 property under the ethernet node without rgmii2_pins on the GB-PC1 devicetree.

2022-02-15T16:11:45Z

Fix pinctrl-0 items under the ethernet node to be size-1 items. Current notation would be used on specifications with non-zero cells.

staging: mt7621-dts: align resets with binding documentation

2022-01-26T12:05:26Z

Binding documentation for compatible 'mediatek,mt7621-sysc' has been updated to be used as a reset provider. Align reset related bits and system controller node with binding documentation along the dtsi file.

Change phy-mode of gmac0 to trgmii to match the other side, port@6. Flow control needs to be enabled on both sides to work. It is already enabled on gmac0, enable it on port@6 too.
