* 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: clean up useless dts partition labelsShiji Yang2024-02-21
| | | | | | | | | | The previous NVMEM eeprom conversions[1][2] left a lot of partition labels that were no longer used. They can be removed now. [1] https://github.com/openwrt/openwrt/pull/13584 [2] https://github.com/openwrt/openwrt/pull/13587 Signed-off-by: Shiji Yang <yangshiji66@qq.com>
* ramips: drop redundant label with new LED color/function formatChristian Marangi2024-02-07
| | | | | | | | | Drop redundant label with new LED color/function format declared. This was needed previously when the new format wasn't supported by leds.sh functions script. Now that is supported this property can be removed in favor of the new format. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

* ramips: mt7621: enable unused PCIe port to fix potential boot failureShiji Yang2023-03-26
| | | | | | | | | | | | | One user reported that his SIMAX1800T couldn't boot like the others. After debugging, I found that this was caused by the disabled PCIe port. I cannot reproduce this issue on my SIMAX1800T. But when I disabled pcie2 on the ASUS RT-AC57U, I got the same result. It seems that disabling these unused PCIe ports on some mt7621 revisions will cause PCIe to fail to initialize. So we'd better to re-enable them on all related mt7621 devices.

* ramips: improve support for H3C TX180x series devicesShiji Yang2022-12-17
| | | | | | | | | | | 1. Explicitly declare gpio pin groups to ensure that gpio works properly. 2. Override bootargs in device tree to avoid modifying u-boot envs during initial installation. Tested on H3C TX1801 Plus Signed-off-by: Shiji Yang <yangshiji66@qq.com>
* ramips: add support for H3C TX1800 Plus / TX1801 Plus / TX1806Shiji Yang2022-07-31
H3C TX180x series WiFi6 routers are customized by different carrier. While these three devices look different, they use the same motherboard inside. Another minor difference comes from the model name definition in the u-boot environment variable. Specifications: SOC: MT7621 + MT7915 ROM: 128 MiB RAM: 256 MiB LED: status *2 Button: reset *1 + wps/mesh *1 Ethernet: lan *3 + wan *1 (10/100/1000Mbps) TTL Baudrate: 115200 TFTP server IP: 192.168.124.99 MAC Address: use address(sample 1) address(sample 2) source label 88:xx:xx:98:xx:12 88:xx:xx:a2:xx:a5 u-boot-env@ethaddr lan 88:xx:xx:98:xx:13 88:xx:xx:a2:xx:a6 $label +1 wan 88:xx:xx:98:xx:12 88:xx:xx:a2:xx:a5 $label WiFi4_2G 8a:xx:xx:58:xx:14 8a:xx:xx:52:xx:a7 (Compatibility mode) WiFi5_5G 8a:xx:xx:b8:xx:14 8a:xx:xx:b2:xx:a7 (Compatibility mode) WiFi6_2G 8a:xx:xx:18:xx:14 8a:xx:xx:12:xx:a7 WiFi6_5G 8a:xx:xx:78:xx:14 8a:xx:xx:72:xx:a7 Compatibility mode is used to guarantee the connection of old devices that only support WiFi4 or WiFi5. TFTP + TTL Installation: Although a TTL connection is required for installation, we do not need to tear down it. We can find the TTL port from the cooling hole at the bottom. It is located below LAN3 and the pins are defined as follows: |LAN1|LAN2|LAN3|----|WAN| -------------------- |GND|TX|RX|VCC| 1. Set tftp server IP to 192.168.124.99 and put initramfs firmware in server's root directory, rename it to a simple name "initramfs.bin". 2. Plug in the power supply and wait for power on, connect the TTL cable and open a TTL session, enter "reboot", then enter "Y" to confirm. Finally push "0" to interruput boot while booting. 3. Execute command to install a initramfs system: # tftp 0x80010000 192.168.124.99:initramfs.bin # bootm 0x80010000 4. Backup nand flash by OpenWrt LuCI or dd instruction. We need those partitions if we want to back to stock firmwre due to official website does not provide download link. # dd if=/dev/mtd1 of=/tmp/u-boot-env.bin # dd if=/dev/mtd4 of=/tmp/firmware.bin 5. Edit u-boot env to ensure use default bootargs and first image slot: # fw_setenv bootargs # fw_setenv bootflag 0 6. Upgrade sysupgrade firmware. 7. About restore stock firmware: flash the "firmware" and "u-boot-env" partitions that we backed up in step 4. # mtd write /tmp/u-boot-env.bin u-boot-env # mtd write /tmp/firmware.bin firmware Additional Info: The H3C stock firmware has a 160-byte firmware header that appears to use a non-standard CRC32 verification algorithm. For this part of the data, the u-boot does not check it so we can just directly replace it with a placeholder. Signed-off-by: Shiji Yang <yangshiji66@qq.com>
