* ramips: remove model name from LED labelsAdrian Schmutzler2020-10-021-7/+7
| | | | | | | | | | | | | | | | | Like in the previous patch for ath79 target, this will remove the "devicename" from LED labels in ramips as well. The devicename is removed in DTS files and 01_leds, consolidation of definitions into DTSI files is done where (easily) possible, and migration scripts are updated. For the latter, all existing definitions were actually just devicename migrations anyway. Therefore, those are removed and a common migration file is created in target base-files. This is actually another example of how the devicename removal makes things easier. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: move dts-v1 statement to top-level DTSI filesAdrian Schmutzler2020-09-251-1/+0
| | | | | | | | | | | | | | | | | 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 ramips, 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 mtxxxx/rtxxxx DTSI files 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 top-level SoC-based DTSI files, and removes all other occurences. Since the dts-v1 statement needs to be before any other definitions, this also moves the includes accordingly where necessary. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: use hex notation for *-mtd-eeprom propertySungbo Eo2020-05-081-1/+1
| | | | | | | Change "0" to "0x0" for consistency. This is an extension of commit 34abfb6e91d1 ("ramips: convert mediatek,mtd-eeprom from decimal to hex notation"). Signed-off-by: Sungbo Eo <mans0n@gorani.run>
* ramips: replace pinctrl property namesChuanhong Guo2020-04-121-2/+2
| | | | | | | | | | | | | | Upstream pinctrl driver in drivers/staging uses groups/function/ralink,num-gpios instead of ralink,group/ralink,function/ralink,nr-gpio Replace these properties in dts as well as the pinctrl driver in patches-4.14. This commit is created using: sed -i 's/ralink,group/groups/g' sed -i 's/ralink,function/function/g' sed -i 's/ralink,nr-gpio/ralink,num-gpios/g' Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
* ramips: simplify state_default/pinctrl0 in device DTS filesAdrian Schmutzler2019-12-231-6/+4
| | | | | | | | | The node pinctrl0 is already set up in the SOC DTSI files, but defined again as member of pinctrl in most of the device DTS(I) files. This patch removes this redundancy for the entire ramips target. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* ramips: add support for ALFA Network R36M-E4GPiotr Dymacz2019-11-131-0/+218
ALFA Network R36M-E4G is a dual-SIM, N300 Wi-Fi, compact size platform based on MediaTek MT7620A WiSoC. This product is designed for operation with 4G modem (can be bought in bundle with Quectel EC25, EG25 or EP06) but supports also Wi-Fi modules (miniPCIe slot has USB and PCIe buses). Specification: - MT7620A (580 MHz) - 64/128/256 MB of RAM (DDR2) - 16/32+ MB of FLASH (SPI NOR) - 2x 10/100 Mbps Ethernet, with passive PoE support (24 V) - 2T2R 2.4 GHz (MT7620A), with ext. LNA (RFFM4227) - 1x miniPCIe slot (with PCIe and USB 2.0 buses and optional 5 V) - 2x SIM slot (mini, micro) with detect and switch driven by GPIO - 2x u.fl antenna connectors (for Wi-Fi) - 8x LED (7 driven by GPIO) - 2x button (reset, wifi) - 2x UART (4-pin/2.54 mm pitch, 10-pin/1.27 mm pitch) headers on PCB - 1x I2C (4-pin, 1.27 mm pitch) header on PCB - 1x LED (8-pin, 1.27 mm pitch) header on PCB - 1x DC jack with lock (12 V) Other: - there is a dedicated, 4-pin connector for optional RTC module (Holtek HT138x) with 'enable' input, not available at the time of preparing support for this board - miniPCIe slot supports additional 5 V supply on pins 47 and 49 but a jumper resistor (R174) is not installed by default - U-Boot selects default SIM slot, based on value of 'default_sim' env variable: '1' or unset -> SIM1 (mini), '2' -> SIM2 (micro). This will work only if both slots are occupied, otherwise U-Boot will always select slot with SIM card inside (user can override it later, in user-space) - U-Boot resets the modem, using PERSTn signal, before starting kernel - this board supports 'dual image' feature (controlled by 'dual_image' U-Boot environment variable) Flash instruction: You can use the 'sysupgrade' image directly in vendor firmware which is based on OpenWrt (make sure to not preserve settings - use 'sysupgrade -n -F ...' command). Alternatively, use web recovery mode in U-Boot: 1. Power the device with reset button pressed, the modem LED will start blinking slowly and after ~3 seconds, when it starts blinking faster, you can release the button. 2. Setup static IP 192.168.1.2/24 on your PC. 3. Go to 192.168.1.1 in browser and upload 'sysupgrade' image. Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
