These patches from Mahesh address places where our SKL-style watermark programming does not match the current bspec rules, either because the bspec was updated after the original code was written, or because new display features (e.g., plane scaling) were added without corresponding updates to the watermark code. Mahesh wrote these patches a long time ago, but due to other churn in the driver they never made it in. The work here is all orthogonal to the atomic watermark stuff I've been doing lately, but landing atomic watermarks did require major changes to the flow of the code in this series, so these patches have been nearly completely rewritten at this point. You can thank Mahesh for any bugs these fix, but blame me for any new bugs they contain. At the moment I've dropped the final patches here for the arbitrated display bandwidth workaround that was previously part of this series; I'm working on a new method of obtaining the data we need for that workaround that's less fragile than the DMI method previously attempted and will post that workaround separately after this series lands.
