* ramips: fix pci/pcie related dtc warningsMathias Kresin2018-08-041-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | That commit exposed a bug in the DTS files used by mt7621 where the wrong reg value for pcie1 (and potentially pcie2) was being used. This was causing WiFi failures for interfaces in pcie1. eg. 2.4GHz working but not 5GHz. As all of these dts entries are already specified in mt7621.dtsi, remove them.

* ramips: add support for TP-Link TL-WR902AC v3Peter Lundkvist2018-03-181-0/+102
TP-Link TL-WR902AC v3 is a pocket-size dual-band (AC750) router based on MediaTek MT7628N + MT7650E. Specification: - MediaTek MT7628N/N (580 Mhz) - 64 MB of RAM - 8 MB of FLASH - 2T2R 2.4 GHz and 1T1R 5 GHz - 1x 10/100 Mbps Ethernet * MT7650 ac chip isn't not supported by LEDE/OpenWrt at the moment. Therefore 5Ghz won' work. Flash instruction: The only way to flash LEDE image in TL-WR902AC v3 is to use tftp recovery mode in U-Boot: 1. Configure PC with static IP 192.168.0.66/24 and tftp server. 2. Rename "openwrt-ramips-mt76x8-tplink_tl-wr902ac-v3-squashfs-tftp-recovery.bin" to "tp_recovery.bin" and place it in tftp server directory. 3. Connect PC with the LAN port, press the reset button, power up the router and keep button pressed for around 6-7 seconds, until device starts downloading the file. 4. Router will download file from server, write it to flash and reboot.
