Adding WDT would lengthen even further the review process. That ignoring I am doing this as a hobby on my spare time and I'd rather spend my scarce free time implementing the power off driver than the WDT (something I'd do out of completion, I have absolutely no use for a WDT in this machine). The reason I am using an MFD is that I was asked to back in v2 (https://lore.kernel.org/all/aHElavFTptu0q4Kj@smile.fi.intel.com/). I'll be CC'ing him. I was told to create a southbridge driver that would match on PCI and registered other devices exposed by it as platform drivers. GPIO was the only functionality implemented at the time, and is the only functionality implemented right now. So I simply delivered was I was asked for.
