From a175bc8f36a43a562e1d1c38f5ff02f4f338dd4d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Antti=20Sepp=C3=A4l=C3=A4?= Date: Thu, 2 Jul 2020 10:53:02 +0300 Subject: [PATCH] ath79: add support for GL.iNet GL-MiFi MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support for the ar71xx supported GL.iNet GL-MiFi to ath79. Specifications: - Atheros AR9331 - 64 MB of RAM - 16 MB of FLASH (SPI NOR) - 2x 10/100/1000 Mbps Ethernet - 2.4GHz (AR9330), 802.11b/g/n - 1x USB 2.0 (vbus driven by GPIO) - 4x LED, driven by GPIO - 1x button (reset) - 1x mini pci-e slot (vcc driven by GPIO) Flash instructions: Vendor software is based on openwrt so you can flash the sysupgrade image via the vendor GUI or using command line sysupgrade utility. Make sure to not save configuration over reflash as uci settings differ between versions. Note on MAC addresses: Even though the platform is capable to providing separate MAC addresses to the interfaces vendor firmware does not seem to take advantage of that. It appears that there is only single unique pre-programmed address in the art partition and vendor firmware uses that for every interface (eth0/eth1/wlan0). Similar behaviour has also been implemented in this patch. Note on GPIOs: In vendor firmware the gpio controlling mini pci-e slot is named 3gcontrol while it actually controls power supply to the entire mini pci-e slot. Therefore a more descriptive name (minipcie) was chosen. Also during development of this patch it became apparent that the polarity of the signal is actually active low rather than active high that can be found in vendor firmware. Acknowledgements: This patch is based on earlier work[1] done by Kyson Lok. Since the initial mailing-list submission the patch has been modified to comply with current openwrt naming schemes and dts conventions.
