* mediatek: dts: use dt-bindings enumerated drive strength valuesShiji Yang5 days
| | | | | | | | | The Mediatek pinctrl driver can only accepts drive-strength values enumerated in "dt-bindings/pinctrl/mt65xx.h". Signed-off-by: Shiji Yang <yangshiji66@outlook.com> Link: https://github.com/openwrt/openwrt/pull/19741 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* mediatek: dts: convert pinctrl bias to the Linux generic styleShiji Yang5 days
| | | | | | | | | | | | | | There are two types properties here that can control the pin bias resistors. "mediatek,pull-{up,down}-adv" and "bias-pull-{up,down}" actually do the same thing[1]. The first type is customized by the Mediatek and the second type is widely used in the Linux pinctrl framework. To avoid confusing developers, unify pinctrl bias to the new Linux generic style.

* mediatek: dts: fix the broken memory nodeShiji Yang5 days
| | | | | | | | | | | | | | Add the missing "device_type" property to fix the memory node. The Linux kernel can not get the memory size without it. Though u-boot can automatically fixup the memory node by adding the "device_type" and "reg" properties if the CONFIG_ARCH_FIXUP_FDT_MEMORY symbol is enabled, it's better not to rely on this optional feature. This patch also adds the reg address for the memory node name to follow the naming rules.

* mediatek: dts: rename mt7981.dtsi to mt7981b.dtsiDaniel Golle2025-05-26
| | | | | | | | | | Upstream uses a different filename, so lets rename our downstream mt7981.dtsi to mt7981b.dtsi and update the device tree of all MT7981 boards accordingly. This is to prepare for the switch to Linux 6.12 which is going to use the upstream mt7981b.dtsi (plus some patches on top). Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* mediatek: add ABT ASR3000 supportTianling Shen2024-07-21
Hardware specification: SoC: MediaTek MT7981B 2x A53 Flash: 128 MB SPI-NAND RAM: 256MB Ethernet: 4x 10/100/1000 Mbps Switch: MediaTek MT7531AE WiFi: MediaTek MT7976C Button: Reset, Mesh Power: DC 12V 1A Gain telnet access: 1. Login into web interface, and download the configuration. 2. Decode and uncompress the configuration: * Enter fakeroot if you are not login as root. base64 -d e-xxxxxxxxxxxx-cfg.tar.gz | tar -zx 3. Edit 'etc/passwd', remove root password: 'root::1:0:99999:7:::'. 4. Edit 'etc/rc.local', insert telnetd command before 'exit 0': ( sleep 3s; /usr/sbin/telnetd; ) & 5. Repack the configuration: tar -zc etc/ | base64 > e-xxxxxxxxxxxx-cfg.tar.gz 6. Upload new configuration via web interface, now you can connect to ASR3000 via telnet. Flash instructions: 1. Connect to ASR3000, backup everything, especially 'Factory' part. 2. Write new BL2: mtd write openwrt-mediatek-filogic-abt_asr3000-preloader.bin BL2 3. Write new FIP: mtd write openwrt-mediatek-filogic-abt_asr3000-bl31-uboot.fip FIP 4. Set static IP on your PC: IP 192.168.1.254/24, GW 192.168.1.1 5. Serve OpenWrt initramfs image using TFTP server. 6. Cut off the power and re-engage, wait for TFTP recovery to complete. 7. After OpenWrt has booted, perform sysupgrade.
