This is missing information on dependant series. Using the u-boot-rockchip
repository which is at
782088de7be7 ("rockchip: imply ADC and SARADC_ROCKCHIP on supported SoCs")

patches 1-3 apply, but patch 4 fails to apply as I seem to be missing some
dependencies.

And the u-boot mailinglist seems to be configured very strangely, as it
seems to rip apart patch-series only sending me some parts.

So far I can at least say, that the u-boot-rockchip repo at the above
commit still boots. Could you please point me to mbox versions
of needed base patches?


Thanks
