[...] What about "power_mpcieX" (or something similar), where X is 1 or 2, depending on what is printed on the PCB (I wasn't able to find hi-res photo)? Take a look at other examples: grep -rn "gpio-export.*power" target/linux/ramips/dts/ target/linux/ramips/dts/HC5861.dts:43: gpio-export,name = "usbpower"; target/linux/ramips/dts/HC5861.dts:49: gpio-export,name = "sdpower"; target/linux/ramips/dts/PBR-M1.dts:78: gpio-export,name = "power_usb2"; target/linux/ramips/dts/PBR-M1.dts:84: gpio-export,name = "power_usb3"; target/linux/ramips/dts/PBR-M1.dts:90: gpio-export,name = "power_sata"; target/linux/ramips/dts/WNDR3700V5.dts:63: gpio-export,name = "usbpower"; target/linux/ramips/dts/TINY-AC.dts:49: gpio-export,name = "usbpower"; target/linux/ramips/dts/ArcherMR200.dts:92: gpio-export,name = "power_usb1"; target/linux/ramips/dts/HC5XXX.dtsi:28: gpio-export,name = "usbpower"; target/linux/ramips/dts/Newifi-D1.dts:56: gpio-export,name = "usb2power"; target/linux/ramips/dts/Newifi-D1.dts:62: gpio-export,name = "usb3power"; --- Cheers, Piotr

Good idea and thanks for the pointer. There does not seem to be any easy-to-find value or id printed on the PCB. However, in some material I was sent from Sanlinking then the slot that can be power-cycled is referred to as mini PCIe 2, so I will rename the slot to power_mpcie_2 and send a v2. -Kristian

OK, I think you can also drop the comment with new gpio name. --- Cheers, Piotr

* The left most mini-PCIe (USB) slot (the one attached to SIM2) can be power-cycled by setting GPIO 0 to high/low. I have no strong opinion on the name, but since the slot can be used for other things than modems I went for usb2. * The D240 only needs the MT76x2 module, so update makefile to reflect this. Note that until the default mt7620 target is updated, then kmod-mt76 (and thus kmod-mt7603) will be selected by default.
