Hi Martin and James,

Please advise how to proceed with this patch series. This patch series
includes an important fix for runtime power management. Unfortunately
the only way to fix runtime powermanagement is by reworking SPI DV and
I don't have access to a setup on which I can test the SPI DV changes.

Thanks,

Bart.
