Here is a v3 of the next generation (previous one is [1]) of the long standing power issue fix regarding to LPSS on Intel Baytrail and Braswell SoCs, in particularly ASuS T100TA. There are few bugs already opened on kernel.org's and RedHat's bugzilla sites. The series depends on the patch submitted earlier [2]. The patch 1 brings a new notification to handle the case when ->probe() of the driver fails. It allows to avoid a potential problems. I've noticed couple of drivers that are using that in assumption that ->probe() never fails. The patches 2 & 4 are needed to fix an I2C issue which Jarkko is currently investigating. It seems the best way to push it through linux-pm tree. Thus, it would be good to get ACKs from the rest of maintainers. Rafael, it would be nice to have an immutable branch or tag for this sice I have more patches coming for dw_dmac driver which are based on top of this series. The patches have been tested on ASuS T100TA, Intel Cherrytrail, and Intel Braswell SoCs.
