* mediatek: add Linksys E8450 supportJohn Crispin2021-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linksys E8450, also known as Belkin RT3200, is a dual-band IEEE 802.11bgn/ac/ax router based on MediaTek MT7622BV and MediaTek MT7915AN chips. FCC: K7S-03571 and K7S-03572 Hardware highlights: - CPU: MediaTek MT7622BV (2x ARM Cortex-A53 @ 1350 MHz max.) - RAM: 512MB DDR3 - Flash: 128MB SPI-NAND (2k+64) - Ethernet: MT7531BE switch with 5 1000Base-T ports CPU port connected with 2500Base-X - WiFi 2.4 GHz: 802.11bgn 4T4R built-in antennas MT7622VB built-in - WiFi 5 GHz: 802.11ac/ax 4T4R built-in antennas MT7915AN chip on-board via PCIe MT7975AN front-end - Buttons: Reset and WPS - LEDS: 3 user controllable LEDs, 4 wired to switch - USB: USB2.0, single port - no Bluetooth (supported by SoC, not wired on board) - Serial: JST PH 2.0MM 6 Pin connector inside device ----_____________---- [ GND RX - TX - - ] --------------------- - JTAG: unpopulated ARM JTAG 20-pin connector (works) This commit adds support for the device in a way that is compatible with the vendor firmware's bootloader and dual-boot flash layout, the resulting image can directly be flashed using the vendor firmware.

* mediatek: mt7622-bananapi-bpi-r64-rootdisk rebase to upstream dtsOskari Lemmela2021-02-24
| | | | | | | simplify maintaining mt7622-bananapi-bpi-r64-rootdisk.dts by storing only differences between upstream dts Signed-off-by: Oskari Lemmela <oskari@lemmela.net>
* mediatek: fix SPDX license identifier on local DTS filesAdrian Schmutzler2021-02-19
| | | | | | | | | | | The SPDX license identifier must be in the first line of a file, unless there is a shebang (then it's the second line). Fix this for the local files, do not care about the upstream patches. While at it, update the identifiers where necessary. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* mediatek: move mt7623a-unielec-u7623*.dts* out of patchDaniel Golle2021-02-19
| | | | | | | Instead of adding those device tree sources using a patch, simply move them to the newly created dts folder. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* mediatek: more clean solution for out-of-tree DTSDaniel Golle2021-02-19
| | | | | | | | | | | Use approach suggested by Adrian Schmutzler instead of introducing another device variable. Also revert the unnecessary white-space changes accidentally introduced by the previous commit.

* mediatek: move out-of-tree DTS files to dedicated dts folderDaniel Golle2021-02-19
Use dedicated dts folder like on ramips to store device tree source files for boards not already supported in vanilla Linux. Doing so instead of having them in files-* has several advantages: * we don't need to duplicate them for several kernel versions * changes to a device tree don't trigger a complete kernel rebuild * the files are more obvious to find Signed-off-by: Daniel Golle <daniel@makrotopia.org>
