* ramips: mt7628: move mtd-eeprom out of root DTSIAdrian Schmutzler2021-08-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | The mt76x8 subtarget is the only one in ramips that stores the mediatek,mtd-eeprom property directly in the "root" mt7628an.dtsi. This is not optimal for a few different reasons: * If you don't really know it or are used to other (sub)targets, the property will be set somewhat magically. * The property is set based on &factory partition before (if at all) this partition is defined. * There are several devices that have different offset or even different partitions to read from, which will then be overwritten in the DTS files. Thus, definitions are scattered between root DTSI and individual files. Based on these circumstances, the "root" definition is removed and the property is added to the device-based DTS(I) files where needed and applicable. This should be easier to grasp for unexperienced developers and will move the property closer to the partition definitions. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* ramips: remove model name from LED labelsAdrian Schmutzler2020-10-021-3/+3
| | | | | | | | | | | | | | | | | 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 Schmutzler2020-09-251-2/+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: 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.

* ramips: remove bogus ralink,mtd-eeprom with offset 0x4Adrian Schmutzler2019-12-271-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices in mt76x8 subtarget use the following line to set up wmac in their DTS(I) files: ralink,mtd-eeprom = <&factory 0x4> This is strange for several reasons: - They should use mediatek,mtd-eeprom on this SOC - The caldata is supposed to start at 0x0 - The parent DTSI mt7628an.dtsi specifies mediatek,mtd-eeprom anyway, starting from 0x0 - The offset coincides with the default location of the MAC address in caldata Based on the comment in b28e94d4bfa1 ("ramips: MiWiFi Nano fixes"), it looks like the author for this device wanted to actually use mtd-mac-address instead of ralink,mtd-eeprom. A check on the same device revealed that actually the MAC address start at offset 4 there, so the correct caldata offset is 0x0. Based on these findings, and the fact that the expected location on this SOC is 0x0, we remove the "ralink,mtd-eeprom = <&factory 0x4>" statement from all devices in ramips (being only mt7628an anyway). Thanks to Sungbo Eo for finding and researching this.
