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
trace_printk() should not be used in production code,
since extra memory is used for special buffers whenever
trace_puts() is used.
Replace it with dev_dbg() which provides all of the desired
debugging functionality.

The problem is that for SDM845 the topology printed by media-ctl
still has the PIX devices. That is even though the PIX interface is not
supported for SDM845 in this driver, the msm_vfeN_pix subdevices
and the corresponding msm_vfeN_video3 devices are still created.
Your patchset is currently missing changes to the hardcoded:
#define MSM_VFE_LINE_NUM 4
struct vfe_device {
...
struct vfe_line line[MSM_VFE_LINE_NUM];
...
};
in drivers/media/platform/qcom/camss/camss-vfe.h.
Thanks,
Andrey
