Thanks for your and Dan's quick reviews! Dan, I have tried your script, it makes the process much simpler, thanks. > It might be worth your while setting up a MIPS cross-compiler so you can > build test yourself.

A sample .config would be very nice and is it correct, that the target tuple is "mipsel-linux" ? > I think the modern approach is to leave the flags as zero, and set flags > via devicetree. > sdhci has > interrupt-parent = <&gic>; > interrupts = <GIC_SHARED 20 IRQ_TYPE_LEVEL_HIGH>; > in device tree, so maybe the 7621 is inverted with respect to other mt > chips? Yes, I have looked into the device tree of mt8173 and there it is IRQ_TYPE_LEVEL_LOW. So the remaining flag is oneshot, currently I'm not completely sure weather it is necessary, maybe the mt7621 has the oneshot save property set. That will need some further investigation! Once I have a cross-compiler ready and compile tested my patches, I will send a version 2.
