Hi All, Our current Crystal Cove OpRegion driver is only valid for the Crystal Cove PMIC variant found on Bay Trail (BYT) boards, Cherry Trail (CHT) based boards use another variant. At least the regulator registers are different on CHT and these registers are one of the things controlled by the custom PMIC OpRegion. This series renames the existing Crystal Cove driver to make clear that it is for the BYT variant only and then adds a new (very minimal) Cherry Trail Crystal Cove driver. Lee, the changes to the mfd code here are very minimal / trivial, I believe that it is best if this series is merged in its entirety through Rafael's tree, can we have your Acked-by for this? Regards, Hans
