This series implements support for the camera subsystem found in the SDM845 SOCs and the Titan 170 ISP. The support is partial in that it implements CSIPHY, CSID, and partial VFE support. The Titan generation of the ISP diverges a fair amount from the design of the previous architecture generation, CAMSS. As a result some pretty invasive refactoring is done in this series. It also means that at this time we're unable to implement support for all of the IP blocks contained. This is due to a combination of legal considerations with respect to the IP and its owner Qualcomm and time & man hour constrains on the Linaro side. The CSIPHY (CSI Physical Layer) & CSID (CSI Decoder) support is complete, but the VFE (Video Front End, which is referred to as IFE (Image Front End) in the Titan generation of ISPs) only has support for the RDI (Raw Dump Interface) which allows the raw output of the CSID to be written to memory. The 2nd interface implemented in the VFE silicon is the PIX interface, and camss does not support it for this generation of ISPs. The reason for this is that the PIX interface is used for sending image data to the BPS (Bayer Processing Section) & IPE (Image Processing Engine), but both of these units are beyond the scope of enabling basic ISP functionality for the SDM845. Since the Titan architecture generation diverges quite a bit from the CAMSS generation, a lot of pretty major refactoring is carried out in this series. Both the CSID & VFE core paths are made more general and hardware version specific parts are broken out. The CSIPHY didn't require quite as radical changes and therefore keeps its current form.
