SA8775P is a Qualcomm SoC. This series adds bindings and devicetree to bring
up CSIPHY, TPG, CSID, VFE/RDI interfaces in SA8775P.
SA8775P provides
- 2 x VFE, 3 RDI per VFE
- 5 x VFE Lite, 6 RDI per VFE
- 2 x CSID
- 5 x CSID Lite
- 3 x TPG
- 4 x CSIPHY
Changes compared to v2:
- Renaming camss-vfe-780.c to camss-vfe-gen3.c and camss-csid-780 to
camss-csid-gen3 to avoid code duplication for SA8775P.SA877P have csid
690 and vfe 690 which is almost same as csid/vfe 780 with very minor
change in register bitfield.
- Restructure vfe and csid addition to reuse existing files.
- Updated commit text for Bindings patch.
- renamed cpas_ife_lite clock to cpas_vfe_lite.
- added voltage rails for csiphy in documentation.
- removed sf and icp clocks.
- removed sf_0 interconnect.
- Link to v2:

Changes compared to v1:
- Renaming camss-vfe-780.c to camss-vfe-gen2.c and camss-csid-780 to
camss-csid-gen3 to avoid code duplication for SA8775P.SA877P have csid
690 and vfe 690 which is almost same as csid/vfe 780 with very minor
change in register bitfield.
- Restructure vfe and csid addition to reuse existing files.
- Updated cisd-lite and vfe-lite interuppt names.
- add enumeration changes as seprate patch.
- Update required fileds in bindings.

We have tested this on qcs9100-ride board with 'Test Pattern Generator'
TPG driver support will be posted in a follow up series.

Rename the file camss-csid-780.c to camss-csid-gen3.c to enable
reuse of CSID logic across multiple SoCs.
The SA8775P SoC includes CSID 690, which is functionally very
similar to CSID 780, with only minor differences in register
bitfields. This rename prepares the codebase for supporting
additional SoCs without duplicating CSID logic.

Add the compatible string "qcom,sa8775p-camss" to support the
Camera Subsystem (CAMSS) on the Qualcomm SA8775P platform.
The SA8775P platform provides:
- 2 x VFE (version 690), each with 3 RDI
- 5 x VFE Lite (version 690), each with 6 RDI
- 2 x CSID (version 690)
- 5 x CSID Lite (version 690)
- 4 x CSIPHY (version 690)
- 3 x TPG
SA8775P is the first Qualcomm SoC to introduce a CSIPHY-based
Test Pattern Generator (TPG).

Add CAMSS_8775P enum, SA8775P compatible and sa8775p camss driver
private data, the private data just include some basic information
now, later changes will enumerate with csiphy, tpg, csid and vfe
resources.

Add support for VFE found on SA8775P (Titan 690). This VFE is
different from vfe 780 w.r.t few register offsets.
It supports two full and five lite VFE.

You don't need to make this into a bool.
version == CAMSS_8775P will do exactly the same logical thing.

I remeber that the > 3 has a purpose but, I don't remember of off the
top of my head what that is.
Please add a comment to state why "> 3" matters.
BTW should this be "> 3" or ">= 3" please double check.

Redefining the same string in separate structures over and over again
seems wasteful.
Please take the opporunity of this new addition to rationalise down the
string declarations and .. if possible the number of struct
resources_wrappers we are doing here.

No need to define the bits here 0xFFFFFFFF is obvious.

This is causing a regression on other platforms because they define
camnnoc_axi but not @ the rate of the pixel clock.
In fact its not very obvious why the CAMNOC AXI would want to have a
pixel clock applied to the interconnect fabric.
The following resolves the regression for me. I can either merge with
this change or I'll have to drop the VFE690 changes until you come back
with something else.

Hi Bryan,
updating camnoc axi to 400Mhz was required for TPG test case.
As of now you can Merge VFE patch with below change.
Meanwhile I will work on an alternative approach to set camnoc_axi and
submit as a separate patch.
