* ath79: enable UART in SoC DTSI filesAdrian Schmutzler2021-02-241-4/+4
| | | | | | | | | | | | | | | The uart node is enabled on all devices except one (GL-USB150 *). Thus, let's not have a few hundred nodes to enable it, but do not disable it in the first place. Where the majority of devices is using it, also move the serial0 alias to the DTSI. *) Since GL-USB150 even defines serial0 alias, the missing uart is probably just a mistake. Anyway, disable it for now so this patch stays cosmetic. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* ath79: move dts-v1 statement to ath79.dtsiAdrian Schmutzler2020-09-251-2/+2
| | | | | | | | | | | | | | | | | | | The "/dts-v1/;" identifier is supposed to be present once at the top of a device tree file after the includes have been processed. In ath79, we therefore requested to have in the DTS files so far, and omit it in the DTSI files. However, essentially the syntax of the parent ath79.dtsi file already determines the DTS version, so putting it into the DTS files is just a useless repetition. Consequently, this patch puts the dts-v1 statement into the parent ath79.dtsi, which is (indirectly) included by all DTS files. All other occurences are removed. Since the dts-v1 statement needs to be before any other definitions, this also moves the includes to make sure the ath79.dtsi or its descendants are always included first.

* ath79: add support for MikroTik RouterBOARD LHG 2nDRoger Pueyo Centelles2020-08-121-0/+87
The MikroTik RouterBOARD LHG 2nD (sold as LHG 2) is a 2.4 GHz 802.11b/g/n outdoor device with a feed and an integrated dual polarization grid dish antenna based on the LHG-HB platform. See https://mikrotik.com/product/lhg_2 for more info. Specifications: - SoC: Qualcomm Atheros QCA9533 - RAM: 64 MB - Storage: 16 MB NOR - Wireless: Atheros AR9531 (SoC) 802.11b/g/n 2x2:2, 18 dBi antenna - Ethernet: Atheros AR8229 (SoC), 1x 10/100 port, 12-28 Vdc PoE in - 8 user-controllable LEDs: · 1x power (blue) · 1x user (green) · 1x lan (green) · 1x wlan (green) · 4x rssi (green) Note: The rssihigh LED is disabled, as it shares GPIO 16 with the reset button. Flashing: TFTP boot initramfs image and then perform sysupgrade. Follow common MikroTik procedure as in https://openwrt.org/toh/mikrotik/common.
