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.
Tested on:
- Qcom RB3 / db845c + camera mezzanine, which is SDM845 based
- db410c + D3 Camera mezzanine, which is APQ8016 based

2.27.0
The CSI-2 spec defines format identifier for Data Type (DT),
and how the Decode Format (DF) & Encode Format (EF) are implemented.
The spec does however not define the DF, EF or Plain Format (PF)
identifiers, as those are vendor specific.
Plain formats describe the size of the pixels written by the RDI
units to memory. PLAIN8 for example has the size 8 bits, and
PLAIN32 32 bits. The appropriate Plain Format is determined by
the Decode Format used. The smallest Plain Format that is able
to contain a pixel of the used Decode Format is the appropriate
one to use.
As the vendor specific identifiers differ between hardware
generations, split them out into separate headers.

2.27.0
Add register definitions for version 170 of the Titan architecture
and implement support for the RDI output mode.
The RDI mode as opposed to the PIX output mode for the VFE unit does
not support any ISP functionality. This means essentially only
supporting dumping the output of the whatever the CSI decoder receives
from the sensor.
For example will a sensor outputting YUV pixel format frames, only
allow the VFE to dump those frames as they are received by the ISP
to memory through the RDI interface.
