Hi Valentin,

Mark applied the DA9062 regulator patch into linux-next yesterday, but looking at my
e-mail history the MFD components are still waiting to be applied I think. The MFD
component has been reviewed in earlier threads ... 

[PATCH V1 1/6] mfd: da9062: DA9062 MFD core driver -- https://lkml.org/lkml/2015/4/17/519
[PATCH V2 1/4] mfd: da9062: DA9062 MFD core driver -- https://lkml.org/lkml/2015/5/14/531 
[PATCH V3 1/4] mfd: da9062: DA9062 MFD core driver -- https://lkml.org/lkml/2015/5/19/523

And the last patch V3 for the MFD seems to have been a little quiet.
But, also there were three other patches with this set,

mfd: da9062: DA9062 MFD core driver 
watchdog: da9062: DA9062 watchdog driver 
devicetree: da9062: Add bindings for DA9062 driver

Hi Lee/Mark,

I'm not sure if the MFD part was missed or if I have not followed the rules properly
on my submissions for DA9062 MFD & regulators. Could I ask if you would take a
quick look please?

Regards,
Steve
