Sebastian,

As my Device Tree changes depend on this modification, we can
synchronize in tree ways:

1/ you provide me a stable branch so that I can pull it before applying
my changes that can go through arm-soc.

2/ you let me take the driver's modifications with me and the two
patches of the series would go through arm-soc.

3/ you take the second patch of my series with my Acked-by tag and carr=
y
both of them up to Linus' tree.

Please tell me your preference.

Thanks, bye,
