Please remove "regulator-suspend-microvolt = <1800000>;" which doesn't
make sense once you have "regulator-off-in-suspend".

Please remove "regulator-suspend-microvolt = <1000000>;" which doesn't
make sense once you have "regulator-off-in-suspend".

Please remove "regulator-suspend-microvolt = <3300000>;" which doesn't
make sense once you have "regulator-off-in-suspend".


Other than those things, this patch looks good to me and feel free to
add my Reviewed-by.  NOTE: when I tried applying this to my tree git
complained and I had to apply manually.  Could you try sending this
patch atop Heiko's for-next tree?  The yell I got:

error: sha1 information is lacking or useless
(arch/arm/boot/dts/rk3288-veyron-fievel.dts).
error: could not build fake ancestor
